German company FKM has expanded its capabilities in 3D printing of components made from copper materials. According to the company, FKM currently manufactures prototypes and small batches of copper alloys and pure copper for customers in the electromobility and energy technology sectors.
Using the laser sintering process, FKM produces complex components from CuNi2SiCr and CuCP materials. According to chief engineer Luis Catarino, this was made possible by powerful lasers that can compensate for the high electrical and thermal conductivity of copper.
Pure copper is therefore suitable for components that require good electrical and thermal properties. The copper-nickel alloy CuNi2SiCr retains its strength at higher temperatures and is used for parts subject to mechanical stress.
FKM sees great potential in additive manufacturing of copper. The technology makes it possible to produce small series of electrical and thermal conductors, heat sinks or motor parts cost-effectively. Thanks to the high degree of design freedom, complex structures could also be realized.
The 3D printing process could therefore represent an economical alternative to conventional copper processing. FKM has already built up expertise in this area and intends to further expand its competencies.
