All the details about Markforged printing materials are here



Nylon with high chemical and heat resistance, reinforced with chopped carbon fiber strands.

Onyx FR

Flame retardant, light weight, and strong chopped carbon reinforced nylon.

Onyx ESD Spool

Onyx ESD

An ESD-safe micro carbon fiber filled nylon composite base material with similar mechanical properties and surface finish to Markforged Onyx.

Nylon White

Non-abrasive, easily painted nylon for repeatedly handled and cosmetic pieces.

Reinforcement Materials

Markforged technology offers the optional addition of continuous fiber reinforcement layers to 3D composite prints.

Onyx FR – A

A flame-retardant short carbon fiber filled nylon that qualifies under 14 CFR 25.853 for most 3D-printable parts. Available on the Industrial Series Printers.

Carbon Fiber FR-A

A flame-retardant variant of the Continuous Carbon Fiber, aerospace-ready “-A” material that qualifies under 14 CFR 25.853 for most 3D-printable parts. Available for Onyx FR-A and the X7 printer

Other materials coming soon, stay tuned!


17-4 PH Stainless Steel

Durable, rigid, and corrosion resistant stainless steel that excels in manufacturing environments and as low volume parts.

H13 Tool Steel

H13 works excellently in high temperature and can withstand drastic cooling. This, coupled with abrasion resistance and machinability makes it ideal for molds and wear resistant pieces.

A2 Tool Steel

A2 tool steel is a highly versatile air-hardening tool steel often regarded as a “universal” cold work steel. It offers a combination of good wear resistance (between O1 and D2) and toughness.


A superalloy that maintains its mechanical properties in highly corrosive and high temperature environments.

D2 Tool Steel

D2 Tool Steel offers excellent wear resistance and is widely used in cold-work applications that require high compressive strength, sharp edges, and abrasion resistance.



Copper is a soft, ductile metal used primarily for its electrical and thermal conductivity.

Coming soon

Stay tuned for the release of new metal materials including 316 and titanium.
