In βTi-alloys, some advances and developments have been reached toward optimizing their mechanical performance and their processability. However, the applications of these alloys via Laser Powder Bed Fusion (LPBF) are still under investigation. In this work, the processing of βTi-alloys via LPBF and their properties is reviewed with a focus on six selected metallurgical systems which are expected to be top-performance materials in applications in the aeronautical and biomedical contexts. These six systems promise a better mechanical and functional performance considering different in-service environments for medical implants and structural applications. After literature analysis, the applicability of βTi-alloys to be processed via LPBF is then discussed considering the relevant fields of applications.
