German research optimizes the quality of 3D printed 18 karat gold with selective laser melting

Research from the FEM Research Institute for Precious Metals and Metals Chemistry in Germany demonstrates a method of selective laser melting (SLM) in gold. The method could give more design freedom to 3D printed jewelry, watches, and even electronics that use gold as a conductor. A 3D printed gold ring. Photo via Broke and Beautiful. Refined gold Though SLM is a popular method for 3D printing titanium, aluminium or steel alloys, the authors explain that “Gold and silver alloys are very difficult to process by laser melting because of their high reflectivity and thermal conductivity.” In order to refine […]
