Desktop Metal, Inc., the Boston-based leader in offering a portfolio of 3D printing solutions, announced it has qualified the use of D2 tool steel for additive manufacturing with the Production System platform, which leverages patent pending Single Pass Jetting™ (SPJ) technology. It is designed to achieve the fastest build speeds in the metal additive manufacturing industry.
Businesses can now leverage 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 moulds with conformal cooling channels.
D2 Tool Steel for Additive Manufacturing
D2 tool steel is a versatile high-carbon, high-chromium air-hardening 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 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.
“Our materials science team is constantly working to develop new materials and processes to make 3D printing accessible to all industries and applications. We are responding to the demand from our customers across manufacturing and industrial industries for materials like D2 tool steel that enable the production of critical forming and cutting tools, and in various other applications where high hardness is valued.”– Jonah Myerberg, co-founder and CTO of Desktop Metal
Desktop Metal’s materials science team has qualified and fully characterized D2 tool steel for additive manufacturing on Production System technology in accordance with ASTM testing requirements.
Cams used in oil and gas or chemical processing applications convert rotary motion into reciprocating linear motion in a machine. Typically these parts require multiple manufacturing steps, beginning with CNC machining and followed by broaching of the spline on a separate machine. Binder jetting enables the production of cams in a single printing step, reducing both the cost and lead time of the part, while also supporting the production of numerous cam sizes in a single build to accommodate different machines, all without any fixturing or tooling required. D2 tool steel is critical for this application because of its hardness and corrosion resistance, which ensures a longer lifetime as the cam mechanically interacts with a sliding pin. In addition, because these components are often integrated into machines operating in harsh environments, the corrosion resistance provided by D2 ensures that the parts will perform as intended and not deteriorate.
