3D Printing News Unpeeled: New Metal 3D Printing Technology

Korean researchers have created a new Metal 3D Printing technology. It uses arc plasma as a heat source and continuously deposits molten droplets of metal. They say that the process has been optimized to be practically layer less and that parts have better properties than WAAM.

University of Michigan researchers Mania Aghaei Meibodi, Alireza Bayramvand and Yuxin Lin have developed a shell wall concrete 3D printing technique that variably deposits concrete while using nonplanar tool paths. This lets them use up to 73% less concrete through printing topology optimized structures. 

Beryllium copper for 3D printing is made by Materion. Using this material for molds for medical devices seems like an exciting application.
