Markforged 3D Printing Materials

Industrial-grade materials for all of your prototype, functional and end-use parts. Print with plastics, continuous fiber & metal materials.

Composite Base filaments are engineering-grade materials that print using a conventional FFF (FDM-style) process. Print with them alone or with Continuous Fibers to yield strong parts. Currently there are 6 composite base plastics to choose from.

Continuous Fibers enable Markforged composite printers to print metal-strength parts. They cannot be used alone, but when printed with a Composite Base, they form the backbone of a strong printed part. Currently there are 5 continuous fibers to choose from.

Our Markforged metal filaments combine the simplicity and safety of FFF printing with the superior properties of advanced metals, bringing metal 3D printing to your benchtop using a 3-step process: wash, sinter, print. Currently there are 6 metal materials to choose from.

Markforged Nylon Material Part

Nylon

Nylon is an unfilled, smooth engineering thermoplastic that can be easily painted or dyed, and parts can be reinforced with any continuous fiber. With an elongation at break of 150%, it’s a non-abrasive material that is great for ergonomic surfaces, assembly trays, cosmetic parts, and workholding for pieces that are easily marred. 

Compatible With:

X7
Markforged Smooth TPU 95A

Smooth TPU 95A

Smooth TPU 95A is a rubber-like material that when used with Markforged composite printers offers product developers and manufacturers the ability to create flexible, impact-absorbent parts on demand.

Compatible With:

Continuous Fibers

Markforged Carbon Fiber Part

Carbon Fiber

Carbon Fiber is a unique, ultra-high-strength Continuous Fiber — when laid into a Composite Base material like Onyx, it can yield parts as strong as 6061-T6 Aluminum. It’s extremely stiff and strong, and can be automatically laid down in a wide variety of geometries by Markforged 3D printers. A special Carbon Fiber variant is compatible with ULTEM™ 9085 Filament.

Compatible With:

X7
Markforged Carbon Fiber Brake Lever

Carbon Fiber FR

Carbon Fiber FR is a flame-retardant variant of Markforged’s unique, ultra-high-strength Continuous Carbon Fiber — when used to reinforce a Composite Base material like Onyx FR, it can yield parts as strong as 6061-T6 Aluminum. Programmatically trace curved features, reinforce holes, and mimic unidirectional fiber layups — all within a few clicks.

Compatible With:

X7
Markforged Kevlar Part

Aramid Fiber (Kevlar®)

Aramid Fiber is a Kevlar® based, specialized Continuous Fiber known for its energy absorption and extreme toughness. When laid into Onyx or another Composite Base material, it yields impact-resistant parts that are nearly immune to catastrophic failure (fracture). It’s perfect for use in parts that are in demanding environments or are subject to repetitive loading.

Compatible With:

X7
Markforged HSHT Fiber Part

HSHT Fiberglass

HSHT Fiberglass is defined by two characteristics: high strength (nearly equal to 6061-T6 Aluminum) and high temperatures. Though not as stiff as Continuous Carbon Fiber, Onyx parts reinforced with HSHT are strong at both low and high temperatures. As a result, HSHT reinforcement is best for parts in high-temperature environments like molds and autoclaves.

Compatible With:

X7
Markforged Fiberglass Part

Fiberglass

Fiberglass is Markforged’s entry-level Continuous Fiber —a material capable of yielding parts 10x stronger than ABS when laid into a Composite Base material like Onyx. Fiberglass is the flagship material of the Onyx Pro and X5 and printable on the Mark Two and X7, providing a more affordable alternative to Carbon Fiber.

Compatible With:

X7
X5

Metals

Markforged 17-4 PH Stainless Steel metal part

17-4 PH Stainless Steel

17-4 PH Stainless Steel is a multipurpose steel used for industrial applications. Heat-treatable to 36 HRC and possessing 95% wrought strength, Markforged 17-4 PH enables you to print high-strength, robust metal parts for a wide variety of applications such as custom tooling and functional prototyping.

Compatible With:

Markforged copper metal part

Copper

Pure copper conducts heat and electricity far better than traditional metals. Markforged Copper possesses better conductivity characteristics than alloyed copper that can be printed on DMLS machines. Unlike conventional fabrication processes which are extremely labor intensive and expensive, Markforged Copper is extremely simple to 3D print.

Compatible With:

Markforged Inconel 725 metal part

Markforged A2 tool steel metal part

A2 & D2 Tool Steel

A2 and D2 are cold work tool steels defined by their extremely high hardness after heat treatment. A2 tool steel is often regarded as a “universal” cold work steel, offering a combination of good wear resistance and high toughness. D2 tool steel is harder and more wear-resistant, but less tough. Both can be used for cutting and forming tools, or other applications where high hardness are valued.
