Below Are 7 Manufacturing Aids Every Machine Shop Should 3D Print
Every machine shop faces the same challenge: increasing production capacity while controlling costs and meeting tighter delivery schedules. Yet many shops continue using valuable CNC equipment to manufacture jigs, fixtures, gauges, and other production aids—taking machines away from revenue-generating customer work.
Industrial 3D printing provides a faster, more flexible alternative for many manufacturing aids. By producing lightweight, application-specific tooling in hours or days instead of weeks, manufacturers can reduce setup time, improve workflow efficiency, and keep critical machining resources focused on production.
From CNC workholding fixtures to inspection gauges and robotic tooling, additive manufacturing is helping machine shops improve productivity, respond faster to engineering changes, and reduce the cost of custom tooling.
Here are seven manufacturing aids that deliver some of the greatest productivity and cost-saving benefits from additive manufacturing.
1. Jigs
Reduce Setup Time While Improving Machining Consistency
3D printed jigs guide tools or workpieces to ensure consistent positioning during machining operations. Whether used for drilling, tapping, routing, part alignment or prototype manufacturing, they help improve repeatability while reducing operator error. Traditional jigs are often time-consuming to machine, especially when they require custom geometry. With industrial 3D printing, shops can quickly produce lightweight, application-specific jigs and easily revise designs as production requirements change.
Benefits
- Produce custom jigs in days instead of weeks
- Reduce tooling costs for low-volume applications
- Create lightweight tools that improve operator ergonomics
- Quickly modify designs for engineering changes
2. Fixtures & Workholding Tools
Increase Machining Accuracy & Throughput by Reducing Setup Time & Ensuring Repeatable Part Positioning
Reliable workholding tools are essential for maintaining accuracy throughout machining, assembly, and inspection processes. Custom fixtures help secure parts consistently while reducing setup variability. Because many fixtures are unique to a specific component or production run, they are ideal candidates for industrial 3D printing. Instead of machining dedicated fixtures from aluminum or steel, manufacturers can produce durable polymer fixtures much faster and at a lower cost for many applications. These custom fixtures are commonly used for CNC machining, inspection, assembly operations, and prototype or low-volume production, where fast turnaround, repeatability, and flexibility are critical.
Benefits
- Reduce setup time between jobs
- Improve repeatability and part consistency
- Produce custom fixtures for complex geometries
- Quickly replace worn or damaged tooling
3. Gauges & Inspection Fixtures
Improve Quality Control While Reducing Inspection Time & the Cost of Custom Inspection Tooling
Quality depends on consistent inspection. Custom gauges and inspection fixtures help verify dimensions, improve repeatability, and simplify quality control. Because inspection tooling often changes as products evolve, industrial 3D printing enables manufacturers to rapidly produce custom go/no-go gauges, inspection nests, CMM fixtures, and measurement fixtures without the cost or lead time of traditional machining. These tools are commonly used at quality assurance stations to support faster, more consistent inspections, helping manufacturers maintain product quality while minimizing production delays.
Benefits
- Faster access to inspection tooling
- Lower cost for custom gauges
- Improve inspection consistency
- Quickly update tools as designs change
4. Templates
Standardize Repetitive Operations to Improve Consistency, Reduce Errors, & Shorten Production Time
Templates provide repeatable positioning, marking, trimming, or cutting guidance across manufacturing operations, helping standardize repetitive tasks while improving consistency. ecause many templates prioritize customization, speed, and repeatability over extreme strength, they are excellent candidates for additive manufacturing. They can be designed around complex part geometries and easily modified as production requirements evolve. Commonly used for welding, fabrication, layout and marking, and secondary machining operations, 3D printed templates help manufacturers improve accuracy, reduce setup time, and maintain consistent results across repetitive processes.
Benefits
- Rapid production for new jobs
- Easy customization for unique parts
- Lightweight and ergonomic designs
- Lower cost than machined alternatives
5. End-Of-Arm Tooling (Eoat)
Increase Robotic Efficiency With Lightweight, Custom Tooling That Improves Cycle Times & Production Flexibility
End-of-arm tooling enables robotic systems to grip, position, and manipulate components throughout automated production. Because weight matters in robotics, replacing heavier machined components with lightweight 3D printed tooling can reduce robot payload, improve cycle times, and enable application-specific grippers without the cost or lead time of traditional manufacturing. Common applications include pick-and-place systems, vacuum grippers, custom robotic fingers, and material handling solutions, where lightweight, customized tooling helps improve robotic performance, increase production flexibility, and accelerate automation initiatives.
Benefits
- Reduce overall robot payload
- Improve robotic efficiency
- Produce custom grippers quickly
- Simplify design iteration
6. Assembly Aids
Improve Assembly Efficiency by Reducing Operator Errors, Increasing Productivity, & Supporting Standardized Work
Assembly aids help operators consistently position and assemble components while reducing fatigue and minimizing errors. Common applications include assembly nests, alignment guides, tool holders, and operator support fixtures that improve repeatability and workflow efficiency. Because assembly processes frequently evolve, manufacturers benefit from tooling that can evolve with them. 3D printing makes it easy to optimize designs, improve ergonomics, and produce replacement tools on demand. These tools are especially valuable in high-mix manufacturing environments where operators frequently assemble different products or configurations.
Benefits
- Reduce assembly errors
- Improve operator productivity
- Enhance ergonomics
- Support continuous process improvement
7. Forming Tools & Soft Tooling
Shorten Tooling Lead Times & Free CNC Capacity by Replacing Traditionally Machined Tooling With Production-Ready 3D Printed Alternatives
Forming tools support bending, shaping, and secondary manufacturing operations such as sheet metal forming, composite layup, and other production processes. Common applications include sheet metal forming tools, composite layup tooling, prototype tooling, low-volume production tooling, and soft tooling for secondary operations. While high-volume production often requires hardened metal tooling, many prototype and low-volume applications can benefit from production-grade 3D printed tooling. Custom forming tools can take weeks to manufacture using traditional methods. Industrial 3D printing dramatically shortens tooling lead times, allowing manufacturers to validate designs, begin production sooner, and preserve valuable machining capacity. A great example is Saratech's work with Stretch Forming Corporation (SFC), where additive manufacturing dramatically shortens tooling lead times from months to days while freeing CNC equipment for customer production work.
Benefits
- Reduce tooling lead times
- Lower prototype tooling costs
- Validate designs before investing in production tooling
- Free CNC machines for revenue-generating work

Real-World Success: How SFC Accelerated Tooling Production with 3D Printing
One of the biggest questions manufacturers have when evaluating additive manufacturing is whether 3D printed tooling can withstand real production environments. Stretch Forming Corporation (SFC), an aerospace manufacturer that produces forming tools for the aerospace, defense, space, and industrial sectors, faced a common challenge. Producing aluminum and Medium-Density Fiberboard (MDF) tooling using traditional CNC machining was both time-consuming and expensive. Every tooling project tied up valuable machining capacity that could otherwise be used to manufacture customer parts.
Saratech partnered with SFC to transform legacy drawings into 3D CAD models and produce custom forming tools using industrial 3D printing. The printed tooling was designed for use in SFC's forming machines, enabling the company to produce first-time quality parts for inspection and customer delivery.
The results demonstrated the impact additive manufacturing can have on tooling production:
- The first production-ready forming tool was delivered in just three business days.
- Saratech produced 22 custom forming tools in approximately two months—a project SFC estimated would have required at least six months using its traditional manufacturing process.
- The printed tools delivered the strength and dimensional accuracy required to form metal parts while significantly reducing tooling lead times.
Beyond the initial project, the partnership helped SFC reduce tooling cycle times, shorten production lead times from weeks to days, and free valuable CNC capacity for higher-value production work. The success also led to an ongoing collaboration focused on additive manufacturing, build-to-print services, and part automation.
