A2 and D2 Tool Steel

Cold work tool steels optimized for a wide variety of manufacturing applications

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.


  • Forming Tools, Stamping Dies, Punch Dies

Precise PLA

A cost-effective thermoplastic for design validation

Precise PLA is our easy-to-print plastic for precision concept modeling and validation. Based on the most common 3D printing prototyping material, Precise PLA 3D prints without warping and comes in a variety of colors. Best of all, it’s affordable. So you can use as much as you need to fine-tune your designs before implementation.



  • Part prototypes, Fit check, Color coded indicators

Smooth engineering thermoplastic that can be easily painted or dyed

Nylon is an unfilled thermoplastic. It’s a non-abrasive material that is great for ergonomic surfaces and workholding for pieces that are easily marred. It can be painted or dyed.

Continuous Fiber- WATCH VIDEO

Carbon Fiber

The backbone of aluminum-strength composite parts

Carbon Fiber is Markforged’s 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.
