Digital Metal, a Markforged company, has announced the availability of H13 metal powder for all Digital Metal Binder Jetting (BJT) Additive Manufacturing machines. The powder will go under the name DM H13 and is a hot-work tool steel that can maintain its strength and hardness when exposed to high temperatures. It also exhibits good resistance to thermal fatigue and abrasion.
H13 is commonly utilised in tools such as extrusion dies and injection moulds. Adding this metal to the company’s portfolio is intended to expand the number of mission-critical applications that can be solved on location and on demand. Highly complex H13 parts can be additively manufactured with properties tailored to application-specific requirements through post-sintering heat treatments.
While final properties vary depending on heat treatment conditions, the ultimate tensile strength of the as-sintered metal is 1350 MPa with a yield strength of 800 MPa. The as-sintered material achieves a 97% relative density at 40 HRC.
Those interested in learning more can see examples of the powder at Digital Metal’s Formnext booth, Hall 12.0, C127.
