BigRep Large Format 3D Printing Virtual Demo Transcript
0:04
All right, great. Well thank you guys all for joining. I'm really sorry that we can't actually be together in person live. But this is kinda the next best option is Zoom, which I'm sure you guys are all super familiar with by this point during this crazy time. I'm Abby Delaney and I am the marketing manager at BigRep. And to welcome you all, whoever she'll demo. Next housekeeping. We will do Q&A throughout the demo, So Chris will go printer by printer, and after each printer, we will pause for Q and A The goal of this is to really be interactive, and like I said, since we can't actually be together, we want to try to make as much interactivity between you guys as we can. So we'll have a few pause. Chris is live. The whole thing is live So we will apologize now if something happens But we're really live And that's kind of really important to us so that you can see see everything from this field And So I think that is all from my side. So I'm gonna go ahead and turn things over to Frank.
1:00
Thanks Avi and again, welcome everybody. My name is Frank, Mary Gel on the US. President for Big Rep America and happy to have you here. As I mentioned, we would have loved to have you at a trade show, unfortunately. The current environment is not allowing us to do that, So thank you for joining our virtual demo. We're not gonna waste too much time here today. I wanted to just take one minute out, just to introduce you to big graph. I have no slides, Just, a little bit of a description bigger was founded in 20 14. I don't know if if you know that it's a Berlin based company from the beginning started on large format plastic extrusion systems. That's all we do from 20 14. We have more than 500 installed systems. Globally are 500th customer happened to be a customer that has four systems making end use, part covers for water ....
2:00
So we're pretty excited about that customer and our 500 customers. But our customers are doing a variety of things.
2:07
We have a lot of Fortune 100 companies that really are pushing the limit of extrusion technology large format comes in a lot of benefits. And Chris is going to explain some of those today when he, when he gives a demo. So I'm not going to talk about that. We started in the beginning, as a global company, so from the start the company opened an office in the US, and in Asia, our US office is where Chris Lee, and I'm not here today, which is just north of Boston, Massachusetts. Wilmington, Mass, or Asia office is in Singapore, and our Europe is in Berlin with our headquarters. And last thing for me to make a successful subsidiary, which I've been willing for a long time, you need to have all of the structure and support locally. So, human, we are a berlin based, German engineered company, we're proud of that, but to make it successful, we need to have the logistics here. So, if you need a spare part, you know, Sarah Tech can get it from our, so, our storage location.
3:12
We have a storage just and there are off office in PV, Massachusetts, when you buy a system.
3:19
You buy it from our Massachusetts warehouse, a spare parts are Filament. Our with our shop is a US shop. And the stock comes from our US. Warehouse, sales service. Customer support and logistics all need to be local for this relationship to be successful, and that's what big rep has done from the beginning.
3:41
So, from that, I'm going to end here, turn it over to you, Andy, tell us a little bit about Sara ....
3:49
Yeah, Sure. Thanks, Frank. Thanks, Abby, and the big rep team for working with us on this live demo. I'm really excited. You know, like like Frank said, this is the best thing that we can put together without being able to, to do this live in person. But my name is Andy Deal. I'm the VP of Marketing at Sarah Tech, and we are an engineering company based out of Southern California Mission Viejo. But we do have sales and technical people all across the country.
4:24
And we work with top tier OEM, like Big ****, like Siemens, to provide companies that are in design, or manufacturing, with the tools that are needed for product development.
4:39
And once the key thing that I want you to know, is that serotype, we don't just sell the product. We are an engineering company. So, we have our own development in-house, and we actually use the tools, the software, the 3-d printers, you know, in house, in our own product development. So we understand those challenges from a customer standpoint, and we work with a lot of customers across the country, from small sized organization to multinational companies, and helping them with optimizing PLM optimizing product development and 3-d printing. So, I'm glad you are able to join us today, and looking forward to eventually, Hopefully, at some point, need all of you.
5:28
All right, great. Well, Chris, this is your I kinda two minute warning here, so before we go live over to Boston, we're just gonna launch a quick poll here. Just looking, are you currently 3-d printing within your organization? Yes, no, or unsure? This just kind of helps Chris and Andy and Frank with their discussion as we kind of continue along here. So results are coming in, it's pretty split. Half and half yes, no's. Right now the yeses are taking the lead.
5:56
I'll give it a few more seconds, get your votes in.
6:01
one more anybody else?
6:04
All right, let's end. This four here and I will share the results. So, about 60% said, Yes, you're currently printing. 40% said, no, and I'm really glad to see that nobody's not sure, but, so that no category, that layer will see if we can sway your mind there in terms of that. So, thank you for answering that, and with that, we're gonna go live over to Chris. Are you there, Chris Mary? Alright, there's Chris value.
6:31
All right, Good to go. Thank you, Frank. Thank you, Andy for the introductions. My name is Kristie. I may application and technician for bigger, unaccompanied by Amnon Emami. Our Operations and Service Manager will take about five minutes to go through each printer with Q and A in between each one in there by the end of it. Hopefully, as I said, we'll get everyone has a big, big yes for 3-d printing. So, the first machine we have here is our big rep one. As Frank mentioned earlier, they grew up has been around for six years. This was our flagship machine. This current model, is the third generation of the, they grew up one.
7:14
We call it the bigger up one, due to its large volume of one cubic meter, and the one.
7:21
As you can see, it offers a view extrusion capability.
7:26
So if you wanted different colored parts, material parts, maybe didn't processes all within a single job because of the dual extrusion in our license software which we'll get into later. We have a lot of versatility and flexibility on how our customers can print what they need.
7:43
So terms of quality and resolution, we offer various sizes on our do extrusion, anywhere from zero point six mm all the way up to two.
7:55
So depending on how fast you want the print to go and how good looking for it to go, you have the options to go to really, fast, May not look as good, but if you then go to eight zero point six, it may take longer, But it will work a lot better.
8:13
The Gayatri itself, you can see, is well engineered. By German engineering, That's what we expect by. That's what we trust.
8:22
I think we have.
8:23
Since we are alive, I think we've just made Franke. Are you still there?
8:27
Yes. That's OK.
8:29
First time. That's happened the first time. That's happened. Alright, I'm gonna figure out what's going on. Frank. And Andy, why don't you guys maybe address a couple of questions here.
8:37
We've got, what does large format mean, and why? Why is it important in today's 3-d printing industry?
8:46
Yeah, Andy, let me take that first. I'd like to comment on that. I love answering the question, because people look at the big one that Chris was just looking at, and saying all one meter cube. I don't have parts anywhere near that size, but we find that the benefit of using a large format printer to have mostly flexibility.
9:07
So large format really is those parts printed that are bigger than basically the alternative. So the desktop printers are 200 or 300 mm square and cubed and the anything that needs to be bigger can easily be printed on a large format. But sometimes you have one dimension that is bigger. So that having the flexibility to have to lay it down in a certain way and be able to print that one dimension, or sometimes you have one dimension that you need to run in the X direction.
9:47
So the last thing before, it sounds like you're ready to go back to Chris. The last thing is, like when we were printing the shield's during the PPE and the beginning of this pandemic, you could print one off on a desktop printer but we could print 50 of them at one time.
10:07
So, you could push print at the end of the night, go home, and then come back and, you know, you were to have industrial level production and Any addition to that before we go back to Chris: Yeah. I mean, we, we talked to a lot of customers and really, you know, the size, the print envelope, is sometimes the limits are, right? So, what would enlarge format? system like I like what bigger app has? It kind of removes that that thought restriction that people have when when when you're looking at design part. When you look at how you approach something. So, it really gives you a lot of freedom when it comes to creating or designing parts for, for what you need to do.
10:55
All right. Great. It looks like Chris, back now, he is back, but now he's saying, Yes. We also sideways. Like I said, we said, This is live, and you also have a tropical storm coming in. So, I'm sure that's not helping our connection rather good answer. Good answer.
11:12
Yep.
11:14
Yep, you're better now, look better and you're in the Tariff Act.
11:17
So where do you do, or do you guys lose me?
11:21
We heard about the nozzle size. I would say that was maybe the last thing, OK, we lost you awhile ago. Well, that's OK, I'm sorry every time I say it. So OK. So the nozzles, anywhere from zero point six to two mm diameter, so what that allows for is a variety of resolutions and speeds.
11:42
So, based on how good you want to look, versus how fast you want to get it, we have those options, too, really, allow the customer to make it an idea that they like, whether their priority is the speed, or the quality.
12:01
Like I said, it's loud. So you do have a phone call coming in, sensitive.
12:05
So the Gayatri itself is controlled by the nanotech step motors in the X Y as well as the Z with the large plane that we're dealing with. It does take a lot of engineering, a lot of German engineering to be able to get the quality, the throughput of Layer one versus Layer 5000. Then, as Frank mentioned earlier, that German engineering is really what we strive towards and what we use to succeed with our models that you'll you'll be seeing.
12:40
The positioning tolerance of the motors is 100 microns in the X Y and then 20 microns in the Z. So even over entire build points, you're gonna get very accurate, very repeatable parts on ML. Want to take us to the backside of machine. We'll talk a little bit about materials and material handling.
13:01
So they grew up, offers a wide variety of big or certified materials anywhere from TPUs to PLA, to even some carbon fiber materials outside of that grant has a open material platform.
13:21
So other materials, it's the 2.853 mm diameter filaments in these large tools here.
13:29
Grip so schools anywhere from two ... all the way up to eight kilograms. And then depending on the type of material. So this guy here is your standard PLA immaterial and the box is our bigger TPU, called .... The reason why we have it in the box is to make sure moisture and humidity stays out of the material.
13:51
And just, you know, the environment.
13:53
That way, we're not getting any quality issues or missing, you know, parts during the during the French first to ensure that everything will print well, and you're not going to be getting any bugs or root issues along the way.
14:11
So, some safety features and other quality of life features at the bigger one has obviously the outer filaments sensor is required as you're running to day to rebuild long builds.
14:24
Once the machine recognizes that there's no more filaments, it will give a sequence to the machine allowing the user to feed on more material and then, continue the grinch, like nothing.
14:38
The user panel is linux based, pretty straightforward.
14:43
When it comes to your, your friends getting them set up, You can either do USB upload or if you had the printer on Ethernet, you can upload the jobs on a separate computer. You cannot start them from that separate computer just because of the safety requirements.
15:01
You want to ensure that someone's always on in front of the printer before you go.
15:08
one thing I forgot to mention was the bed itself. The bed is quarter inch aluminum and then the orange sheet that you see on top is a polyamide that we call kept on them. So, that kept them from does is two things. It protects the integrity of the bed.
15:26
And then, it also helps with materials, Asian, or certain materials. So, heart removal.
15:34
the bed gets upwards of 60 to 80 C when that schools, once a part is done, it releases apart from the bed. Sometimes, we also use a 3-d printing adhesive called Magic.
15:49
So, that magic ..., it is water based.
15:51
So, between the thermal process, that cooling as well as using a bit of water to release magical, it really doesn't take much to get the big parts off the bed and making sure that they're still level and and flat.
16:09
That's a good intro so far. Abby, any questions from the audience? We do have a few questions. You did talk a little bit about materials. Can you just talk a little bit more about what materials are available on the one?
16:21
Yeah so the one very clearly is open to the environment. So materials like ABS, nylon, ASA. Because when you print them at a large scale they do release toxic fumes on this machine, civically. They will not work but we do have a couple other machines that will allow that.
16:39
So on the one, it's all your more standard materials, so I can grab a couple pieces.
16:48
The black material that is on there now, Yes, that is our OpEx or TPU.
16:54
Then we have an ABS like material called Pro Each team. Approach T's are most versatile are mostly used material, because it has very similar thermal and mechanical properties to ABS but it doesn't have the toxicity. We definitely sell that and use that The most on are, not see it, Prince very well.
17:16
We can do this. Single extrusion would support support moves very easily afterwards, and then is also compatible with a couple of different materials produced.
17:26
So we've done a few parts where it was like, a live hinge, or card, or something. We would have the TPU material function as the hinge, And then the ... be the load bearing part.
17:40
You know, have that print in I infill percentage, and we would do that all in one go because of the dual extrusion. And that was a project on the one.
17:51
Great, this is an application question but I'm gonna let Christiana Frank maybe jump in with a little bit more detail. It says, Structurally, how durable are the parts? If you're a furniture manufacturer, can you sit on apart? And it not crush it? Yep. I think one example was.
18:08
So yeah, there we go.
18:12
So this guy here, what's printed in our big rep POA.
18:16
Again, PLAs your most standard polymer, for FDM printing this does that 8% info. We tested this awhile back.
18:25
It's about just under one thousand pounds of vertical force before it actually buckles. So I think ... go sit on that together before, before this thing, breaks down and all that.
18:38
So we have other customers do larger pieces of furniture outside of the small studio here.
18:46
We're going anything from 1 to 1 couches, bath fixtures.
18:52
Really anything you can imagine, I mean, I am moving into a new apartment about a month, so I have been thinking about the same stuff. So the machines down and they do a steward to my place. Nice. OK, next question, Can you explain the semi automatic leveling?
19:11
Yep.
19:12
So another requirement of a bed size is to ensure that each point, from one corner to the other, is all on the same zy plane.
19:22
So in order to get that tolerance, we have a inductive sensor next to the extruders, pretty much like, a fancy proximity sensor to where it reads various points around the bed.
19:37
And then, underneath the bed, we have a couple legs that we used for adjusting, It'll go around the bed a few times. We make those adjustments to plus or zero mm. So, to put that into perspective, it's about half the thickness of a human hair, so, very tight tolerances and after we do this a couple of times during installation, there really is no need to do it again, unless you're moving it from one location to another.
20:05
Great. You mentioned two nozzles.
20:07
Is one nozzle for support and one for the part, or is it possible to print two materials and make a hybrid part?
20:14
Yep, it is possible.
20:15
So as I mentioned, with that Live Hinge model, you can have, for each T on one nozzle, TPU, the other nozzle, print them in the same part. Or maybe you wanted to do one model in ..., and then an entirely different model in TPU. You can do that as well. So instead of having that loss of time, or changeover, like, if you wanted to start a print at 6 0 PM, and it's only six hours, well, you're not going to come in at midnight.
20:44
So you can just add on the second build, the second part, and the same build, and then have to do both of them single extrusion, and then you want to have that loss of time that you would, right?
20:58
Great. What's the max weight that you've printed?
21:02
Maximum wage, Newsmax volume.
21:05
And then I've done a couple where they pretty much Maxo for X, Y, and Z, if I had to guess how heavy it was, probably 2 or three spools materials.
21:17
So anywhere from 20 to 24 kilograms heavy. So it took Amnon and I together to get that thing off.
21:29
We can get some some large parts, definitely.
21:32
All right, great, I think that's all the questions we've got for the why. And let's turn the camera there.
21:37
And walk over to the proud, perfect.
21:42
Machine, sorry, wait one more. Just kinda more. Yeah, sorry, one of my second. Can you enclose the one?
21:47
You can.
21:48
Yes, because the one's been around for about six years, we have a couple of different options or enclosing it one that we so and then have some customers want to do their own little custom enclosure based on their warehouse safety requirements. We've done a couple side projects with them to make sure that it's well sealed and it'll still print well, or whatever to you they want. So, like I said earlier, we are open source with our materials. And then, through us through their attack will have the support to get those materials running as well as possible, whether they need an enclosure, dry boxes, whatever it may be.
22:34
Alright. Sorry. There's another one. Just came into the bigger up one, run over the weekend and finish a job without somebody being there to monitor it the entire time, Of course. Yep.
22:45
We've had these guys run seven days, 14 days, you know.
22:50
Our schools are upwards of eight kilograms iPads and customers use 25 kilogram schools so you could have that thing run for three weeks straight, not care, and have a giant part done when you get back.
23:04
And is there a way to monitor it remotely?
23:07
Yes.
23:07
So, you can get the printer on Ethernet or Wi-Fi connection. So, in addition to the remote job upload, we do have a ... webpage where you can monitor the job via a webcam. It says it comes as an accessory.
23:25
And you can also see the the G code in a way. The figure out how much has been printed, the ..., and then how much is actually gage roughly how much is left, and then also tell you, in hours, minutes, seconds.
23:39
How long, OK, now it's safe to go.
23:44
I'll go slowly in case anyone has a question, because I love time at the end. For a few more questions. Coming up on time. Yeah. All right. So, this guy here is the big red row. The biggest pro is, I think, a huge step from the bigger one in terms of throughput material and then the amount of data that we're able to process with these nodes.
24:07
So the two main reasons for that, one, is a new type of extrusion technology called M X T and then pairing that with high-end CNC control systems from Bosch extra. That allows us to do some pretty cool things.
24:24
So first off, the X T with the bigger one and with most industrial 3-d printers, the limiting factor on how fast you can go is the thermal process. So you're always having to wait for your material to feed and eat up and then Extrude out. With the M X T we now have a small pool of pre mounted filament.
24:49
so that you're no longer waiting on that melting process.
24:52
Now, the limiting factor is actually how fast you can move the extruders and the gantry back and forth to still maintain quality.
25:01
And the next thing was the CNC control systems, so with foster extra, were able to just gather so much data, anywhere from XYZ location to temperatures to extrusion rates to fan the fan rates, low rates, everything.
25:18
So with that in mind, once you have all that data and ran to understand that data, a project you come in, you need 100 units. We need to understand what's a good unit, what is a bad unit?
25:31
And with the data that we have at the machine well known, the machine will tell us, you know, is this in spec, is out of spec. What is our spec, what does that mean. You can dictate what your spec is, whether it's XY location. Maybe you don't want it to go too far away.
25:48
Things like that.
25:51
Just a little bit under the hood.
25:55
So if you don't want to use the ..., the reason why customers don't is that at this time, E M X T is just a few materials right now. Because of the new technology does take a little bit longer for R&D to fully certified materials.
26:09
you want the range of materials like the bigger one, plus a few more, we have a H X shooter, same nozzle sizes as the one, series 62 point O.
26:22
In addition to the materials that I mentioned on the one because the print chamber is enclosed because of the ambient heat coming in the bed, we can print things like ASA, EBS, nylon. Yeah. So your carbon fiber.
26:40
And then based on the material combinations you want to do, you can do, to EDX teams, to aces. takes maybe 5, 10 minutes to get them changed out.
26:52
And then, again, you have that flexibility and versatility of all the options we have.
26:57
And then there's always a, a perfect solution to whatever application, to whatever job you want to get printed.
27:05
And then another couple of features. You have the webcam, which comes standard with the big red row.
27:13
You can see the higher in control systems, the motors in the back. So right now, we do have to use Extruders on the printer right now.
27:26
This model here was printed in for each T, that was a non toxic EBS SQL extrusion. And the reason why we did a single extrusions that with the Brooch TV supports for them are quite easily.
27:41
Because we're using engineering grade materials, we need to have a more concerned effort on pre processing those materials.
27:52
We have a heated chamber on the left here and then a not needed chamber on the right. You can switch them out depending either chamber over here, as I mentioned this before, you TPUs. Your water soluble supports, anything like that. And then on the other side, even have your approach to use your PLAs.
28:14
Things like that.
28:15
Just to make sure the quality of the prints are, are as good as they can be.
28:21
So, just a little sneak peek under the hood, just to show you the complexity of the machine, and really the backbone of what we're working with.
28:32
So we've had the pro there, maybe a year, a year and a half now, And I think even, at this point, we're just getting our feet wet with the throughput and the amount of data that we're grabbing from, from these controllers.
28:46
So, comparing the one to your standard industrial printer, probably 1.1, zero point two times as fast, If you compare the one to the pro, the pro is already 2 to 3 times as fast as the one. And I thank you very soon will be upwards of 3 to 5 times as fast at least.
29:18
Awesome.
29:21
Cool.
29:24
So the pro does have the magnetic interlock doors just for your extra safety so no one can gain access while it's sprinting.
29:39
And then the Pro HDMI, HMIS the Human Machine Interface. This is run off of Windows. The bit more user friendly for our software guys.
29:49
It makes it a lot easier for software upgrades, you know, as soon as they get rolled out, will be able to remote into your machine and do those updates, no cenp-a..
30:04
And like the one, you can get it on Ethernet or WI Fi connection and be able to remold the upload jobs and then monitor the jumps progress would be on board camera.
30:20
Because of the wider range of materials, the bed can get upwards of 80 to 90 C.
30:28
The one is about ADC at max, maybe 75.
30:32
And then the nozzles are upwards of 250, 300 C.
30:41
Any questions? We have few questions. What is the power requirement for the Pro? And I guess while we're at it, maybe, what does it for the one as well?
30:49
Yep, so both the one and the pro are 2 8 2, 240 volt. The one is a 20th bug, whereas the pro is a 30.
31:03
Great.
31:05
What's the approximate footprint of a pro footprint. So about six feet tall. So it's six feet ish.
31:15
Maybe seven feet wide, and then about 8 to 10 feet back.
31:22
So, it's a big machine, You know, with the large load volume, and then the larger eligible cabinet in the back it needs a space.
31:31
Do you have a part there that you could do a comparison of time print on of what it would be on that pro ana for the one?
31:39
Yep, So, mentioned there was 200 times best on the pro compared to the one.
31:48
So, for example, you're still here takes about 24 hours in our approach C using a one mil nozzle on the one.
32:00
If we use a OneNote nozzle on the pro, it will take about 12 hours.
32:08
All right. Great.
32:09
I'm not sure that you have this data handy, but how does the accuracy of of print on a pro compared to that of an SLS printer on an SLS, so it is different technologies.
32:23
So, like I said, with the one, it's 100 microns X Y and then 20 microns and the Z with the Bosh, it's maybe 15, 20% better and we're already at really tight tolerances and we're at ortho on. The ones are probably read, though.
32:40
On the pro.
32:42
For Yeah, yeah.
32:43
I don't have the direct comparison with the SLS at this time, but we can get that for you if you really need the answer.
32:50
Great. OK, next question, if I have a production injection molding material such as ABS, is it possible to formulate it to run a pro?
32:58
And, if so, how hard is it?
33:01
Yeah, so when you transfer over an injection molded part to FDM, one of the biggest differences we see is the wall thickness.
33:13
So with injection molding, you're able to get enter parts, and you're able to get the mechanical strength with an X, Y, and Z about the same width, FDM. We unfortunately don't have that luxury. We can get it pretty comparable based on the material. But it's not perfect, but what we have with our slicing and then with our machines, we can either increase the thickness or even working with the resellers, and they grew up, we can transition that part from injection molding to designed for FDM prints very well, and still get the same output.
33:55
OK, I'll just follow up on that one more to the material properties, or maybe and Frank, and talk to it to customers that are printing injection molding instead of traditional manufacturing.
34:08
Mean, if it's the same strand of ABS and it comes in a Filament form, we're more than happy to brinton. It should function in the same way.
34:19
Like I said, the mechanical strength, whether you print it in the, X, Y, or Z axis, one side will be stronger than the other configuration vendor swapping.
34:32
Andy, we can follow up with you after. If you've got a part you want to send, christened team. We'd be happy to take a look at it for you. I'll give you them, they can help you. Any more questions on the pro? I think we've got most of them answered.
34:46
Just for time. I want to make sure we get to the G two, so let's keep walking.
34:57
So, the last machine that I'll be showing you today, is the little baby of the, the bunch, The big studio G two, the G two is the second generation. Obviously, a step up from the G one.
35:12
The G two is fully enclosed, similar to the big rip bro.
35:18
It has the same control systems as the one, so you're not going to have the same speed as the probe, but you're happy. You'll have the same material output as the pro.
35:31
So, the build size on the studio is one meter long by a half meter wide and a half meter tall, similar to the pro. It has heated filament chambers.
35:43
So you have your controls here, or it's easier to 1 or 2 nozzles, as well as the Chamber itself.
35:51
We do have active cooling on the upper end of the printer.
35:58
If it does get too hot based on material, for example, PLA doesn't like a whole lot of heat, so we would set our print chamber low.
36:07
But if we're doing carbon fiber or an ABS, we would set our film and chambers here to like 35, 40 C, ad that dry out. And then we would set our print chamber to a higher temperature itself. So all that E is contained.
36:23
And they'll get a nice, smooth print for that high grade material.
36:30
See?
36:36
The bed is the same configuration as the one in the pro quarter inch and luminal, with that kept on film on top.
36:44
So the Kapton film is actually a consumable item, and that, over time, depending on the customer and the parts and how they get removed, that does get damaged based on how they remove parts.
36:59
The good side, or the good thing is that it takes about hundred bucks worth of material and then half an hour to replace it. And then you can use it for six months a year. Again, depending on outpatient you are to remove the large parts.
37:18
And although we don't have it on board right now, there is a camera similar to the Pro that comes standard.
37:27
So you can get it on Ethernet and monitor everything. Make sure it's printing well.
37:33
So what we have going now is actually just large volume of print samples that will be sending out to all of our resellers. Just making sure that all of our new materials are well-known and resellers and customers can have them readily available to field them, go through Ben Tests, and just make sure they know what they're getting before they get admission.
37:57
And then lastly, with the word ..., it has the same.
38:04
PC panel, like the bigger ones. So you can go through all of your print menus. You temperature controls. So with any installation, will be there anywhere from a day to three days, depending on the customer's preference, and ability, and we'll go through anywhere from lights and training, to calibration to maintenance, whatever's needed on there. And so on the topic of maintenance, on the day-to-day, there really isn't a whole lot.
38:36
Once the bed is, level, it pretty much stays for a very long time unless you move it.
38:43
The biggest concern for maintenance is maintaining grease on the spin those and then making sure there's no dust or leftover debris on the build. When you start a new job, just to make sure you're not gonna get any collision score, it's useless.
39:01
Right. We got a few questions. What is the print speed in mm per second on all the machines?
39:09
So, that does vary based on the knowledge of size, as well as the resolution. In general, it'd be more material that you're feeding out at one time. The harder it is to control. So, in general, the slower we would go.
39:25
If we were doing a 0 six nozzle, which is standard on the G two and we can get anywhere from micron layers, we could push that 2340. I've used before Millimeters a second, but then on the tumor nozzles, we can do 1.11 point 2.
39:50
Well you're heights, and that we can push that maybe 40, 50 mm a second.
39:55
But, because we're doing 10 times as many layers compared to 0 one to the 1.2, overall, the throughput would be better on the two my nozzle because we're having to do as many loops.
40:13
What about build failures with power outages? What, what happens?
40:18
So, during installation, what the technician's do is calibrate the Z axis.
40:25
It will count the amount of steps, going up and back down, and that is then stored in the printer.
40:33
And so in the case of a power outage, when you turn the printer back on, you will be prompted with a notice. Do you want to continue the job where you left off?
40:43
As long as you don't move the extruders in V X, Y, what the printer will do is go all the way up in the Z, count those steps, go all the way back down.
40:55
Remember where they left off in the G Code, and then Continue.
41:02
And, what's, What is the temperature range for the base, and the Chamber?
41:07
So, the print bed on the G two, upwards of 80 to 90 C, the chamber itself is not actively heated, but because of the ambient heat from the bed, because it's so large compared to the extra chamber, the print chamber can get upwards about 40 to 45 C.
41:29
And then, if it does get a little bit too hot for looking for, we have, the queueing system depends up on top, that will feed it out. And then in the back, we also have Ventilation, if you need to get out the thoughts opinions. If you print the ABS or.
41:47
All right. Great. And I see you've got one good parts in there for this question. Says, What about surface finish surface finish, and any post-processing steps?
41:57
See.
41:58
So this guy here.
42:03
two more steps.
42:03
So this guy here, if you can get a Basically, this is It's yeah, I believe a 0 or 2 or 0 3 glare height. Something like this is about the same. Maybe a year or two. So this is no post-processing.
42:22
Almost all of our materials are it's pretty easy to send them, prime them, and then paint them.
42:31
For example, we have a part on here.
42:38
So, this is one example of a post-process part. So, you can see, actually, on, the back end, is the end that the user does not care about.
42:48
So, just to show you the, the FDM an inside, and then on the exterior yeah, this paired with the nice question. You can get some really good looking pirates, and we can show you a couple more that we have about this.
43:07<
Hmm, I think one of my favorite builds is the one car here printed in three pieces left right Center.
43:20
A little bit of sanding, priming painting, you can get it really cool, 1 to 1 scale model, like this.
43:27
If you're looking for more heavy duty, kinda gorgeous parts, we do offer.
43:36
Metal plating like we have in this manifold here.
43:41
So, if you're pushing maybe a viscous fluid through here and you don't want to know this out.
43:50
Me, obviously 3-d printed it and then nickel plated. This is pretty lightweight compared to a CNC part.
43:58
And because you are concerned about the chemical resistance, this does exactly looking for in or the time of the gods.
44:08
OK, great, one more question and this may I'm giving you the one minute warning here to go. To get ready. last question, is, how often do you have to replace the nozzles?
44:19
Depends on the material ..., we've had machines run on the same zone for about a year.
44:26
If you're doing tours like pets, yeah, aye.
44:31
It does take a little bit more of a toll on the HUD. And so our ... are hardened steel, so they're meant to withstand.
44:39
All right for materials like that.
44:41
So then we usually have customers that every six months, more just preventative maintenance, they're meant to withstand for awhile and they didn't.
44:53
All right, great. Well, if we have any time at the end of this, we'll take a few more questions, but I'm going to launch one more quick poll here while Maggie gets her computer setup to do blade. So next poll question here. Let's talk about some challenges.
45:09
So what is your biggest challenge? Those of you that are printing with additive materials, speed, size, budget, you're just not sure.
45:21
People are voting, they're coming in, lots of challenges.
45:24
So far, our budget is leading the way here, we'll give a couple more seconds here.
45:32
Get your votes in Maggie's Reddy 3. 2 1.
45:38
Alright, let's see the results here. So budget is the biggest challenge with additive, followed by materials speed and size and then kind of unsure there.
45:49
So thank you for that.
45:50
Right, Maggie's coming to you live from New York somewhere there, I think. You're young here in Brooklyn, New York.
46:01
I'm just going to talk to you very briefly, about, bled our in house slicing software. So blade has been developed for the last couple of years, in Berlin with our R&D team, or engineer's team, and our materials team.
46:15
So essentially, we wanted to come up with an option for an easy to use slicer. That was made specifically for large format printout.
46:23
and then even more specifically for big rep machines, it allows great control for your printing. We provide you with all of the presets a few things, you'll probably notice, it has a bit of a similar layout to Kara. So if you're familiar with cure, this will probably be an easy program for you to adapt to.
46:45
The biggest part of blade, and the biggest step that we wanted to make from using a third party software was to really get accurate print time and material usage, so optimizing your prints to the maximum capacity.
46:58
So, as you can see here, I'm looking at the Studio G two.
47:02
We do have on the left here all of our machines, so once you download blade, which is free on our website, you're able to load up all of the machines that big Red Produces. But for now, I'm just going to work for the G two, since that's the machine that Chris ended with. And we're actually gonna look at that Manifold part that he showed you.
47:22
So, right now, I'm in the Prepare View. You can have a look up here, also. I'll quickly, very quickly, go through, sort of, the layout here. This is your dual extruders.
47:33
So, essentially, this is where you would select your Material, and tell it which extruders you're using.
47:41
So with the studio G two is zero point six nozzle only. So that's why that's our only option here. But you do have all of these materials.
47:49
and it will let you know, with an error, if a material is not compatible with that specific machine or nozzle size, then you can also set material for your second extrovert. Or if you decided to do a dual extrusion imprint. Otherwise, you just have your basic tools over here in terms of scaling movement, rotation. The other thing that's really special about blade as its batch printout So it is able to do batch printing. If you load up one STL you can fill the whole build, play automatically with that part and it'll fill it in a way where nothing is going to crash and nothing is going to happen.
48:25
You can fill it up for printing all parts at one time, or for printing parts, one at a time, depending on what you want to achieve.
48:34
Then, the other thing that's really special that was an added feature in blade is also the orientation, the automatic orientation of your part, so if you're not sure, the best way to print your part in terms of saving on material costs or saving on print time, this program will actually do it for you.
48:54
So I'm going to just switch over. I've already slice the part, I'm gonna switch over to preview mode. So now you can sort of see what it's gonna look like on the bed once it's printing, or rather when it's finished printing. Over here, you have I won't go through all these, but essentially these are where you would also select your layer height. As I said, everything is preset for you and done by our team. So selecting your material, nozzle, size, and layer height is essentially all you have to do. If you have more experience with 3-d printing, you have a really specific part and you can go in here and you can start to play around with things.
49:28
There are very interesting options that are available to you.
49:32
Then the last thing, so as you'll see here, I have it actually in the color scheme line mode and the View type of layer view, so you can actually watch and see how your apprenticed kind of build-up.
49:43
So, if I just zoom around here, everything is color coded and you can click on this and it'll tell you what those colors actually mean. There is an explanation for everything.
49:54
Then, yeah, you can slice down here on the right hand side and just watch how your part builds up. So it's a really great preview as well, to see how your part actually is going to look like. It gives you an extremely accurate time estimate.
50:07
And it also gives you the amount of material you're going to use. And it breaks it down even further than that. So if you hover over the info button and it tells you what each aspect of your part and how long it takes, as well as if you do a dual extrusion print, it'll break down the two materials usages for you.
50:24
The last thing is, Yes. Just saving to file, as Chris mentioned, mentioned earlier, if you're connected directly to your machine with Ethernet and with your laptop, you're able to actually just load through that Wi-Fi connection, or a network connection, rather, I should say, your G code onto your machine. Otherwise, you would save file to USB, and then you would bring it over to your machine and upload it.
50:50
So that's about it, I think, for me, unless anyone on my team has anything to add, or if there are questions. We just had, a couple of questions. one came in, do have to use blade.
51:01
You only have to use it for the pro machine due to the ... technology which is unique to the Grep. Otherwise you can use other third party softwares and we do still have files for Simplify 3-d if you decide to go that route. But the latest free It's it's what we work with so we do highly suggest Working with this program.
51:23
I only had one more question. What would a typical upload time be for this manifold example?
51:30
I'm gonna assume you mean upload onto the machine in terms of G code to actually slice the file, it takes about NaN, and it's the same for uploading onto the machine.
51:39
It's going to be a really quick upload, I think, the longest upload, I've had a part That maybe is maximum Bill volume, on the one, and was an extremely complicated mention that maybe took a minute.
51:51
All right, great. All right, so I have saved one question for Andy and Frank, and I launched our last poll here as we kind of go into our closing session, here, is in terms of applications, but what application? Are you currently 3-d printing prototypes tooling, patterns, and mold and use part something else, or not printing yet. Let's see what everybody's doing out there.
52:14
Last poll question, I promise. I'll make sure you're all still awake.
52:20
I'll give a few more seconds here.
52:24
Right.
52:26
I'll just one more covenant. Alright, and then this year, we'll share the results. So, prototypes is the number one. And the second one is tooling for jigs and Fixtures. So thank you all for answering that.
52:40
And that ties very well into our last question that came in a while ago from Michael and I told them we'd get to it, but he says, What have you found to be the highest and best uses for each printer?
52:52
Send that to us. I'm saying, guys, yeah. Fantastic. So, the higher end printers have more flexibility. They do cost a little bit more, a little bit more detailed and precise, but they're able to run more accurate and higher end materials, so it's really what you want to do with it. Are you looking for volume, high-end functional prototypes that you need a particular mechanical property? Then, that's the pro and the G to the pro can do it in a bigger footprint. It can do it faster. It has a better system controls with the .... So, if the systems run perfectly, and you have the nozzles and using the materials and everything is running.
53:40
As it's supposed to, know that G two in the pro have similar results at similar nozzle and and layer height outside of speed, but the product, so many other features on top of it, the one and the we're enhancing the one all the time.
54:00
Soon, we will have a hard and nozzle for the one, also, with the ability to run more engineering materials also, but having the open frame machine does have its limitation, has great access, but some limitations as well. So, that's my answer. If you're just looking for a simple peel, a friend, or you're looking for a bio ABS and and the environment is clean, so, the open machine, the big rip one fits the pro and the G two too much more engineering solutions and higher end materials and geometric accuracy and higher spec.
54:47
Andy?
54:48
Yeah, also, um, the thing that I want to point out is a lot of time, people just think about end use part, right.
54:58
But there, there are a lot more applications for 3-d printing that just you and use parts, right? There's Jason fixture, tooling, no work holdings and things like that. So it really depends, like Frank said earlier, what your needs are and working with a lot of customers throughout the years, I guarantee you if you are doing production And if you have a sharp running, we can walk through with you. And find application for 3-d printing within your shop floor. A lot of time.
55:34
Because companies, and, and, you know, people are thinking about thing, a certain way You don't see the application. Or how you can approach using 3-d printing in different ways to kind of maximize its benefit. And we work with a lot of companies that are walking through and see what they do, and there's, There's always 1 or 2 recommendations that we can make for 3-d Printing that is applicable to what they're doing today.
56:06
Andy, I just want to say that is a perfect reason that big rap and Sarah attack our partners, because you're an engineering company, and you're not trying to sell a box. You're not trying to sell a printer. You're trying to sell a solution. And for the past year and a half or so, bigger app is evolving from a system provider to a solution provider. We have an engineering solution team. So, along with Sarah Tech and big graph, we want to solve problems and we don't just want to sell machine. So, please, if you have a problem with CNC programming with some kind of fixture with some kind of prototypes, that that's not going to want to do, it's wasting too much time or it's not functionally, what you are looking for. You know, give Sarah Tech a call, and we're here to support them with all kinds of solutions. Last thing, Abby.
56:55
I know, we just hit the limit, but when we talk about the custom things, I just want to mention, we have some automation in the scan to part, or the STL. Apart from adjacent fixture standpoint. And also one of our most exciting new products is custom, was started from Airbus. So we call it now the air box where you can make custom shipping, creates automatically from either a scan park or or from an STL and it will withstand the right, G forces and totally eclipse. And protect that part that you're trying to shipping and Airbus needed it because they were getting damaged parts and they were spending thousands and thousands of dollars and I'm gonna throw it to you for the last word.
57:54
Great. thank you, Frank. And once again, I'd like to thank the big rep team for, for being here. And I'd like to thank everybody for joining us today. Hopefully we showed you some, some useful thing, and, you know, what we challenge you to do is to go back to your work, and, and, you know, see, what, what can you do with this technology?
58:15
And if you need help, let us know. Um, you know, like like Frank said, we're engineering company big rep as an engineering company, over half of our employees are Degreed Engineer. So I know, big rep as well. A lot of technical and smart people onboard, So we're here to help, and thanks for joining us today and looking forward to see you in the near future. We can all be in person.
58:40
Right. All right, with that? Yes, great point there, Andy. So, thanks, Andy, and Sarah Tech and Frank, thanks. Chris, and I live in Boston, and maybe they're in New York, and I really hope it felt like we were together, I really did. I felt like I was kinda part of the hurricane there. That was happening with, Chris, there, but, as I did mention on the call, you know, our team, A volunteer then, if you had a part, like, the one person that was asking about the injection. Well, you've got apart or our team is great at giving a part analysis. They can kind of guide you through that process, and, you know, let you know their recommendation. Same thing with Andy's team as well. So with that, thank you guys all for being with us here today for this hour. With that Stay safe, stay, healthy and Go big Rep.
