Pure Copper Printing Material

Digital Metal now adds pure copper to its extensive material offering for metal binder jetting. Freedom of design coupled with the thermal and conductive properties of pure copper open new possibilities within many industries.
Digital Meta, a leader in high-precision metal binder jetting systems for industrial use now adds pure copper, DM Cu, to their material offering. The excellent thermal and electrical conductivity properties of pure copper make it ideal for a wide range of applications. Good conductivity, or heat transfer, is for example a requirement in electronics, heat exchangers, heat sinks and engine parts. 3D printing of components in copper also offers unprecedented freedom, enabling design for optimal functionality with very few restrictions. In addition, copper is known for its antibacterial properties. For further information see the IDTechEx report on 3D Printed Materials Market 2020-2030: COVID Edition.
A key benefit for Digital Metal's customers is that printing with 99.9% pure copper brings out the best of the material compared to copper alloys commonly used in laser-based systems.
"Printing with pure copper using Digital Metal's binder jetting technology is one of the most anticipated material launches ever, and totally new within binder jetting. Copper has been high up on our customers' wish list and timing is perfect with the demand for copper applications soaring in fast growth areas such as e-mobility and heat conductivity. We have been developing the process for some time internally, but I would really like to emphasize the value of the excellent cooperation with key customers in our fast-growing Digital Metal User Group. It has been a great help and we are now very pleased to deliver a high-quality copper process for Digital Metal binder jetting," said Christian Lönne, CEO at Digital Metal.
Pure Copper, DM Cu, is the latest addition to Digital Metal's binder jetting system. Other materials in the range are stainless steel 316L and 17-4PH, tool steel DM D2, super alloys DM 625 (equivalent to Inconel 625) and DM 247 (equivalent to MAR M247) and Titanium Ti6Al4V. Digital Metal is constantly working on expanding the material offers in close cooperation with its parent company Höganäs AB, the world's largest metal powder manufacturer.
