Farsoon develops advanced pure copper Additive Manufacturing process

Farsoon Technologies, headquartered in Changsha, China, has announced the development of a pure copper Additive Manufacturing process using the company’s metal laser sintering systems. Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity, which is widely used in industries such as aerospace, automotive, shipbuilding, electronics. However, the vast majority of additive copper is currently based on alloys of copper, not a pure metal.
Many applications can only be unlocked with low-oxygen, pure copper. Pure copper has a high laser reflectance rate of over 90% with standard laser based AM systems and it is difficult for the laser to continuously and regularly melt the pure copper powder, which leads to issues such as interface failure and thermal cracking.
