Desktop Metal (NYSE: DM) today announced it has qualified commercially pure copper (> 99.95% purity) for additive manufacturing on the Production System™ platform, which leverages patent pending Single Pass Jetting™ (SPJ) technology designed to achieve the fastest build speeds in the metal additive manufacturing industry. Customers can now leverage SPJ technology for the production of high-performance copper parts at scale across a broad variety of industries, including automotive, aerospace, and electronics.
With its excellent thermal and electrical conductivity, commercially pure copper is an ideal material 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. It is the third-most-consumed industrial metal in the world.
“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. “We are excited to be able to expand our extensive Production System materials portfolio to support customers looking to 3D print electrically and thermally conductive components at scale and at a fraction of the cost of conventional manufacturing methods.”
Desktop Metal’s materials science team has qualified and fully characterized commercially pure copper (C10300) printed on Production System technology with greater than 99.95 percent purity, enabling excellent thermal and electrical conductivity. Manufacturers can now print copper parts on the Production System with significant geometric complexity in a single step instead of brazing multiple conventionally produced copper components together, eliminating a time-intensive and expensive process prone to error and waste. With the geometric freedom enabled by binder jetting, engineers can also explore new, high-performance designs not possible with conventional manufacturing methods, such as the lattice structures and conformal cooling channels to improve heat transfer.
