Desktop Metal qualifies 316L stainless steel on Production System 3D printing platforms

Metal desk has qualified the 316L stainless steel material for use on its production system platform.

The company believes the addition of this material will enable users of its metal binder jetting systems to produce end-use components that can withstand the most demanding environments.

Boasting corrosion resistance and mechanical properties that allow it to perform well in extreme temperatures, 316L stainless steel would be suitable for applications in marine, healthcare, food preparation and manufacturing environments. pharmaceutical processing, as well as in the automotive industry. After subjecting the material to extensive testing, Desktop Metal has validated it for use on its production system machinery and to the MPIF 35 standards for powder metallurgy structural parts established by the Powder Metal Industries Federation.

The company has also used its 316L stainless steel material to develop a series of application examples, which include a rocker arm for saltwater marine environments, a fluid connector for chemical processing plants, a custom surgical tool and a car gear shift knob. sector. Thanks to the corrosion resistance capabilities of the material, the rocker arm is said to have an extended life, the fluid connector is protected from harsh chemicals and the shift knob is able to withstand the wear and tear required by the parts. high contact. Desktop Metal says it could produce the fluid connector at a rate of 5,500 per week at a cost of $6.85 per piece; the surgical tool could be printed at scales of 24,000 parts per week at a cost of $2.50 per part; and the shift knob up to 6,700 pieces per week. All parts were produced on the P50 production system.

“Qualifying 316L stainless steel with industry-leading mechanical properties on the production system platform is part of our aggressive roadmap to support a range of binder jetting materials and demonstrates the benefits of SPJ technology, which enables mass production throughput without sacrificing part performance and repeatability,” commented Jonah Myerberg, co-founder and CTO of Desktop Metal. “With the 316L on the P-50 production system, Companies will now be able to take advantage of additive manufacturing to produce complex end-use parts suitable for use in harsh environments at volumes and costs competitive with conventional manufacturing.”
