Materials for 3D printing

Digital Metal offers a range of different materials for printing. New materials are constantly under development and will be readily available after rigorous testing.

Latest material release

The latest addition to our portfolio is DM Cu, pure copper (99.9%). The excellent thermal and electrical conductivity properties of pure copper make it ideal for a wide range of applications, such as 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.

A key benefit of printing with 99.9% pure copper is that it brings out the very best of the material. See the material data sheet for more details.
