A newly developed 3D printing process has made it possible to print with alloy containing 99% copper or even 100% pure unalloyed copper. Copper has always been a popular material for its great thermal and electrical conductivity. The pure copper alloy has even a better thermal and electrical conductivity. It consists of 100% IACS with a density of 8.9 g/cm³. Attaining a quality and efficiency higher than achieved by conventional alloys processed in 3D printing since reduced copper content also means lower conductivity.
Common applications for pure copper parts are heat exchangers, Inductors and Cryogenic applications.
✦ High thermal and conductivity properties
✦ 100% IACS
✦ High freedom of design
✦ High resolution
✧ Fast oxidation which means greenish on the part
✧ Fast corrosion
– Inductors
– Heat exchangers
-Cryogenic
Direct Metal Laser Sintering produces high-end metal parts free of residual stress and internal defects.
Selective laser melting utilizes high power-density laser to fully melt and fuse metallic powders to produce near net-shape parts with near full density
