Investigation of elimination of powder spreading in manufacture of thin and wide preheating beads from Co–Cr alloy powders using a P-ebeam
A preheating step consisting of the heating of substrates and powder particles is necessary to prevent spreading phenomenon of powders in an electron beam melting (EBM) process. The preheating step, however, increases the overall manufacturing time as well as the energy consumption of the EBM proces...
