In 2019, Markforged introduced four new metals for their Metal X 3D printer, including Inconel 625 and D2 Tool Steel. Read about all previously released Metal X materials in our related blog post.
Now, Markforged is opening its Metal X platform to even more applications by introducing the ability to 3D print pure, non-alloy Copper.

Overcoming Challenges
In the world of manufacturing, the low hardness values of Copper can make it difficult to machine. Copper also has high reflectivity, which is problematic for many Direct Metal Laser Sintering (DMLS) 3D printers that use lasers to fuse metal powder.
By using the same 3D printing process as all other Markforged metals, Copper can be printed without needing to take precautions against airborne metal powder. In turn, this lets users create parts and geometries that could be difficult to machine. It also reduces lead times that can be associated with outsourcing.

Applications
Copper is widely utilized in areas that require high thermal and electrical conductivity. Because the Markforged Metal X is able to print pure Copper, almost any traditional application is able to be printed and used in either a prototype or end-use fashion. This includes applications such as heat sinks or spot welding.

By taking advantage of the strengths offered by 3D printing, complex geometries such as internal cooling channels can be considered.
Lastly, the Metal X can print solid parts that are 98 percent dense. This leads to consistent performance that is comparable to machined Copper parts. If weight is a concern, the Metal X can still produce Copper parts with an infill. This would would be impossible via traditional machining.
