Engineering-grade materials enable you to use 3D printing to make parts suitable for every stage in the manufacturing process.

Thermoplastic build materials

Every Markforged printed part starts with a base plastic filament extruded from our first print head. Parts made of plastics alone have excellent engineered properties such as toughness, stiffness, stability and strength over other plastic printers.


Micro-carbon reinforced nylon for strong, stiff and heat tolerant parts.
Compatible with: Desktop series, Industrial series

Onyx FR

Flame retardant, meets UL94 V-0 specification down to 3 mm, shares the chemical and physical attributes of Onyx.
Compatible with: Industrial series

Onyx ESD

Onyx ESD is a static-dissipative version of Onyx and achieves between 105 and 10 ohms of surface resistance.
Compatible with: Industrial series

Nylon White

Tough material with smooth surface texture for repeated skin contact or work holding when handling highly polished surfaces.
Compatible with: Mark Two, X7

Fiber reinforcement materials

Reinforce parts with continuous fiber for amazing properties through our second print head. You have a choice of four fiber materials for tremendous boosts in strength, toughness and other properties for the most advanced uses any 3D printer can provide.


For Stronger, Tougher 3D printed parts.
