Desktop Metal makes available Commercially Pure Copper for its Production System series of additive manufacturing devices. Desktop Metal says its new copper achieves < 99.95% purity. 

Copper offers excellent thermal and electrical conductivity, making it ideal for products requiring heat or electricity transfer, such as cold plates, pucks and manifolds, heat sinks, heat exchangers, and bus bars, as used in power-intensive electrical applications. 

The Production System uses Desktop Metal’s Single Pass Jetting technology, which the company says achieves the fastest build speeds in metal additive manufacturing. Copper is the third-most widely used industrial metal, and has been a “highly requested material from our customers,” says Desktop Metal CTO and Co-Founder Jonah Myerberg. The metal 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,” Myerberg adds. 

Desktop Metal says the Production System platform consists of two printer models: the P-1, a solution for process development and serial production applications; and the P-50, a large form factor mass production solution for end-use parts. 

The Production System combines Desktop Metal engineered binders with an open material platform, allowing customers to produce high-performance parts using the same low-cost metal powders used in the Metal Injection Molding (MIM) industry. An inert processing environment enables compatibility with various materials, Desktop Metal says, including high-performance alloys and even reactive metals, such as aluminum and titanium. 

Desktop Metal says the new geometric freedom enabled by binder jetting copper allows engineers to explore new, high-performance designs, such as the lattice structures and conformal cooling channels to improve heat transfer.

Commercially Pure Copper is now available for Production System users directly from Desktop Metal. The company had previously made copper available for its Studio System line of 3D printing devices.
