Abstract Scope Additive manufacturing of titanium parts is a market that has been growing significantly for the past decade. The intricate geometry that the technique offers pushes the growth of the process. However, reclaiming the unused powders from the powder bed is limited because offcuts are generated by the laser that sinters and agglomerates powders near the printed parts. Another source of offcut powders is atomization where the bigger powders are discarded. Recycling these powders and agglomerates has always been an industry challenge, but a recently published work has proven that titanium direct powder forging (DPF) could be used to produce high-quality biomedical grade blanks from these offcuts. The current study looked at the DPF process to produce near net shape parts by including a close die forging step. Results show that high-quality parts can be produced and that the microstructure and the mechanical properties satisfy the biomedical standards.
