Titanium alloys are of increasing importance in aerospace, automotive, marine and biomedical applications due to the combination of high specific strength, superior corrosion behavior, and outstanding bio-affinity. LPBF is a leading-edge rapid prototyping technology through layer-by-layer manufacturing and converting a CAD model into physical parts with powders. LPBF employs a high-energy laser to melt metal powder in a selected area quickly, and contains a quick cooling and solidification process, so as to obtain supersaturated solid solution in a non-equilibrium state as well as uniform and fine metallographic structures.
