Abstract:

The focus of this work is to process new biocompatible Ti alloys solely constituted of non-toxic elements by laser-powder bed fusion (L-PBF), a metal additive manufacturing (AM) technology. The main L-PBF processing parameters such as laser power and scanning speed were defined to obtain highly dense samples. The effects of the addition of ceramic particles and the influence of the scanning strategy on the microstructure of the Ti-based alloys were investigated, showing the possibility for in-situ tailoring the material properties in the L-PBF process. Finally, some prototypes were manufactured proving the feasibility of manufacturing parts of Ti-based biocompatible alloys with complex geometry by L-PBF.
