Markforged Nylon and Markforged Onyx are two plastics with excellent heat resistance, surface finish, and chemical resistance. Both materials can be stiffened with any of Markforged's continuous fiber options. For printing white colored parts, both Nylon and Onyx are interchangeable; however, Onyx is slightly stronger.
Nylon is an engineering thermoplastic that is a versatile material both with and without reinforcing fibers. Parts produced with Nylon are smooth, non-abrasive, and easily painted. Nylon can be enhanced with any continuous fiber and works best for non-marring work holding, repeated handling, and cosmetic parts.
Markforged Onyx is an ideal material for customers who need parts that require real strength and stiffness. Onyx serves as a thermoplastic matrix for Markforged's composite parts. Use Onyx on its own, or further reinforced with embedded continuous carbon fiber, Kevlar, or fiberglass layers.
Onyx is based on remarkably tough Nylon, but also provides parts with stiffness equal to or greater than any pure thermoplastic material available for professional 3D printers. Use Onyx filament for anything from tooling and fixtures to end-use parts.
