BOSTON, November 23 –– Desktop Metal today announced that it has qualified the use of D2 tool steel for the production system platform, which leverages patent-pending Single Pass Jetting (SPJ) technology designed to achieve speeds of fastest manufacturing in the metal additive manufacturing industry.
Companies can now take advantage of SPJ technology for the production of parts in high strength, high temperature applications such as cold work metal forming tools, dies and punches as well as injection molds with compliant cooling channels.
D2 tool steel is a versatile high carbon and high chromium tool steel characterized by its high hardness and compressive strength after heat treatment. This tool steel also offers extremely high wear resistance properties, dimensional stability and corrosion resistance in the hardened state, a key advantage 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 punching and sizing tool elements, cutting and forming dies, shear cutting tools, gauges, burnishing tools and other wearing parts.
“Our materials science team is constantly working on the development of new materials and processes to make 3D printing accessible to all industries and applications,†said Jonah Myerberg, co-founder and CTO of Desktop Metal. “We are responding to the demand from our manufacturing and industrial customers for materials such as D2 tool steel which enable the production of critical forming and cutting tools, and in various other applications where high hardness is appreciated. . ”
Desktop Metal’s material science team qualified and fully characterized the D2 tool steel printed on the production system technology in accordance with ASTM testing requirements.
- Rotating cam
Cams used in oil and gas or chemical processing applications convert rotary motion to reciprocating linear motion in a machine. Typically, these parts require multiple manufacturing steps, starting with CNC machining and followed by broaching the spline on a separate machine. The binder jet allows the production of cams in a single printing step, reducing both the cost and the delivery time of the part, while supporting the production of many sizes of cams in a single construction for s Adapt to different machines, all without any fixings or tools required. D2 tool steel is essential for this application due to its hardness and corrosion resistance, which ensures longer life as the cam mechanically interacts with a sliding pin. Additionally, since these components are often incorporated into machines operating in harsh environments, the corrosion resistance provided by D2 ensures that parts will perform as intended and will not deteriorate.
