Desktop Metal has qualified commercially pure copper for use in its 3D printers.

The 99.95% pure metal powder can now be used with single pass jetting (SPJ) technology to make parts for applications requiring heat or electricity transfer, such as cold plates, pucks and manifolds, heat sinks, heat exchangers, and bus bars used in power-intensive electrical applications.

“Copper has been a highly requested material from many of our customers and prospects, and has applications spanning a broad variety of industries, from thermal hardware found in air and liquid cooling systems to conformally cooled coils for transmission of high frequency currents,” said Jonah Myerberg, co-founder and CTO of Desktop Metal.

Desktop’s Production System additive manufacturing (AM) platform now covers D2 tool steel, 420 stainless steel, nickel alloy IN625, 4140 low-alloy steel, 316L stainless steel, and 17-4PH stainless steel. It can also print customer-qualified materials such as silver and gold. Desktop Metal plans to add additional metals to its portfolio, including tool steels, stainless steels and superalloys.
