Composite and Metal 3D Printing Materials

The strongest 3D printing materials for any industrial applications.


New – Onyx ESD

Onyx ESD is a high-performance and static-dissipative version of Onyx that is stronger, stiffer, and meets stringent ESD-safe requirements. 

Onyx ESD is ideal for tooling and fixtures in static-sensitive or ESD-protected areas, and its sleek surface finish makes it perfect for end-use parts that come into contact with electronic components.

This material is exclusive to Markforged Industrial series printers.

Application Spotlight: Columbia Elektronik AB

Columbia Elektronik AB is a Swedish manufacturer of complete test fixturing solutions for the Nordic electronics industry. The company has seen a steady increase in demand for ESD-safe materials due to the changing manufacturing landscape and rise in the need for more complex electronics

Onyx is a beautiful black filmaent that combines nylon with micro-carbon fibers. A filament that’s not only tougher than other 3D printing plastics— it’s also stiffer, more heat tolerant, and more dimensionally stable.


Fiberglass is the most cost-effective material. It’s as strong as Carbon Fiber, but 40% as stiff, and 2X the weight. Suited to everyday applications where you need strong parts.


Tough Nylon filament is abrasive-resistant, flexible and impact-resistant. Nylon is also easily dyable to achieve any color you might need. It’s a highly versatile 3D printing material both with and without reinforcing fibers.


Kevlar has the best abrasion resistance and is our most flexible material. For when you need parts that are durable and resistant to impact.

Carbon Fiber

Carbon fiber has the highest strength to weight as well as the highest thermal conductivity. Perfect for applications requiring the greatest possible stiffness and strength.

HSHT Fiberglass

High Strength, High Temperature (HSHT) Fiberglass is a material uniquely designed for users who need strong parts in higher temperature environments (over 105°C, with a heat deflection point of 150°C)


17-4 Stainless Steel

17-4 stainless steel combines high strength, corrosion resistance, and hardness, making it widely used in aerospace, medical and petroleum industries. We use it for assembly fixtures and tooling on the Mark X.

316L Stainless Steel (Beta)

Also known as marine grade stainless steel, 316L stainless steel exhibits very good corrosion resistance and excellent weldability.

Titanium Ti-6Al-4V (Beta)

Ti-6Al-4V, also known as Grade 5 titanium, is ideal for lightweight applications requiring high tensile strength and corrosion resistance. It is widely used in aerospace applications such as airframe components and turbine blades.

D2 Tool Steel

An air-hardened tool steel with high carbon and chromium content, D2 trades toughness for great hardness and abrasion resistance. It is often used for cutting tools and dies.

A2 Tool Steel

A2 tool steel is air-hardened with excellent impact resistance. We use it for punches, dies, and form tooling on our industrial series printers.

6061 Aluminum (Beta)

As a general purpose aluminum, 6061 combines good machinability, strength, and weldability. It can additionally be anodized for a good surface finish. We use it for many of the machined components in our industrial series printers.

Inconel 625 

Inconel’s strength combined with its impressive heat resistance makes it ideal for heat and pressure shielding. This superalloy is used in jet engines and medical applications, and is very hard to machine.

H13 Tool Steel (Beta)

H13 is a hot work steel widely used in die casting and tooling applications. Alloyed with chromium, molybdenum, and vanadium, it is known for its strength and resistance to thermal shock.


Known for its high thermal and electrical conductivity, ductility, and machinability, copper is widely used in heat exchangers, as well as electrical and construction applications.

7075  Aluminum (Beta)

7075 aluminum is one of the strongest aluminum alloys available. With  a high strength-to-weight ratio, 7075 is stronger than many common structural steels.
