Desktop Metal is the first company to offer the D2 Tool Steel in a two-step bound metal additive manufacturing process, allowing customers to leverage a simple, nearly hands-free process to produce parts for high-strength D2 applications such as cold work metal forming tools, dies, punches and injection moulds with conformal cooling channels.

D2 is a versatile high-carbon, high-chromium air-hardening tool steel characterised by its high hardness and compressive strength after heat treatment. This tool steel offers high wear resistance properties, dimensional stability, and corrosion resistance in the hardened condition, a key benefit for conformal cooling applications. D2 is used for a wide variety of cold work tools that require a combination of wear resistance and moderate toughness, such as coining and sizing tool members, blanking and forming dies, shear cutting tools, gauges, burnishing tools, and other wear parts.

“D2 tool steel has traditionally been a challenging and expensive material to work with,” said Jonah Myerberg, co-founder and CTO of Desktop Metal. “With this material now available on the Studio System 2, we’ve streamlined production of D2 parts to just two simple steps for improved affordability and accessibility. We are excited to be able to offer our customers this new material with higher hardness after heat treatment than all of the other Studio System materials qualified to-date, unlocking new applications that require tooling material grade strength.”
