Abstract

Powder bed fusion (PBF) processes are laser-based additive manufacturing in which the laser beam scans the selected locations of powder bed at a controlled speed and then it fuses the powder to the solid material by either partial melting in selective laser sintering (SLS) or full melting in selective laser melting (SLM). The aim of this paper is to present a review about PBF showing its way of working, parameters and open issues. In addition, the paper shows the current smart manufacturing that optimize the processes.
