Desktop Metal Qualifies 420 Stainless Steel for Production System

Metal desk has qualified 420 grade stainless steel (420 SS) for use on its Production System metal 3D printing platform.

This comes just weeks after the company qualified nickel alloy IN625 for the production system and also follows recent launches of Ti64 for its Studio System 2 and 316L stainless steel for its Shop System. By enabling 3D printing of 420 stainless steel on the production system, Desktop Metal believes users will be able to mass-produce high-strength end-use parts in industries such as medical, aerospace and consumer products.

420 SS material is a heat treatable martensitic stainless steel that provides high strength, hardness and corrosion resistance to atmosphere, food, fresh water and mild acids when fully hardened . These include frequently used surgical and dental instruments, ball bearings, pump and valve components, hand tools and premium cutlery. Desktop Metal also tested the material on the additive manufacturing of an aerospace valve nozzle adapter, medical locking knuckle bar, and twin-screw extruder mixing elements.

“Engineers continue to pursue metal additive manufacturing as a leading option to drive innovation in design and manufacturing,” commented Jonah Myerberg, co-founder and CTO of Desktop Metal. “We believe our qualification of 420 SS and other high strength alloys will accelerate the deployment of our AM 2.0 solutions to customers looking to successfully mass-produce large-scale critical parts.”

420 SS material joins 4140 low alloy steel, 17-4PH stainless steel, 316L stainless steel and IN625 nickel alloy in production system material portfolio, while multiple customer qualified materials are also supported by the machine. Desktop Metal also announced plans to launch additional stainless steels, tool steels, superalloys and copper materials in its portfolio.
