Office metal qualified the use of D2 tool steel for its production system platform, which relies on patent-pending Single Pass Jetting (SPJ) technology designed to achieve the fastest build speeds of 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 dies and punches of cold metal forming tools, as well as injection molds with compliant cooling channels.
D2 tool steel is a multi-purpose 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.
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.
Created by the inventors of single-pass binder jet and inkjet technology, the production system is an industrial manufacturing platform powered by Desktop Metal’s SPJ technology. It is designed to achieve speeds up to 100 times faster than traditional powder bed fusion additive manufacturing technologies and enable production quantities of up to millions of parts per year at competitive costs compared to conventional mass production techniques.
The production system platform consists of two printer models: the P-1, a solution for process development and mass production applications, and the P-50, a mass production solution to large form factor for end-use parts. The production system combines Desktop Metal engineered binders with an open materials platform, allowing customers to produce high performance parts using the same low cost metal powders used in the metal injection molding industry. (MIM). An inert processing environment allows compatibility with a variety of materials, including high performance alloys and even reactive metal powders, such as aluminum and titanium.
In addition to D2, the production system platform material library has expanded to include 420 stainless steel, IN625 nickel alloy, 4140 low alloy steel, 316L stainless steel and 17-4PH stainless steel, each qualified by Desktop Metal. The platform also supports several materials qualified by customers, including silver and gold, and Desktop Metal plans to add additional metals to its portfolio, including tool steels, stainless steels, superalloys. , copper, etc.
