Pure Copper

Copper is a soft, ductile metal used primarily for its electrical and thermal conductivity. Copper’s high conductivity makes it an ideal material for many heat sinks and heat exchangers, power distribution components such as bus bars, manufacturing equipment including spot welding shanks, antennae for RF communications, and more. The ability to print pure copper using Metal X enables geometrically optimized parts that were previously expensive, time consuming, or impossible to make.

Pure Copper for Additive Manufacturing

Great Heat & Electricity Conductor

Pure copper conducts heat and electricity far better than traditional metals. Markforged Copper possesses better conductivity characteristics than alloyed copper that can be printed on DMLS machines. Unlike conventional fabrication processes which are extremely labor intensive and expensive, Markforged Copper is extremely simple to 3D print.
