Titanium based bone implants production using laser powder bed fusion technology

Additive manufacturing (AM) enables fully dense biomimetic implants in the designed geometries from preferred materials such as titanium and its alloys. Titanium aluminum vanadium (Ti6Al4V) is one of pioneer metal alloys for bone implant applications, however, reasons eliminating toxic effects Ti6Al4V maintaining adequate mechanical strength have increased potential commercially pure (cp-Ti) to be used implants. This literature review aims evaluate production cp-Ti biomedical with laser powder bed fusion (L-PBF) technology, which has a very high level technological matureness industrialization level. The optimization L-PBF parameters post-processing techniques affect obtained microstructure leading various mechanical, corrosion biological behaviors manufactured titanium. All features are considered light specifications needs applications. most critical disadvantages residual stresses deformations introduced solutions discussed. Moreover, manufacturability porous that causes benefit harm applications assessed.
