New laser 3D-printing technique to make metal components

Direct laser melting also called Selective laser melting is a rapid prototyping, additive manufacturing, 3D printing technique. It is intended to utilize a high-powered density laser to melt and fuse metallic powders. However, the technique is likely to experience weld-cracking. Experts at the Laboratory of Thermomechanical Metallurgy of EPFL have created a new laser 3D…
