Titanium alloys—especially Ti6Al4V—are among the most widely used materials in metal 3D printing via LPBF (laser powder bed fusion). The main reason is an outstanding strength-to-density ratio: parts stay light yet withstand high mechanical loads and corrosive environments.
In medicine, biocompatibility matters too. Titanium forms a stable passive oxide layer that the human body generally tolerates well, which is why it is chosen for long-term implants (orthopedics, maxillofacial surgery, dental restorations). Additive manufacturing also enables porous or lattice structures designed to support bone ingrowth and tissue integration.
In aerospace and industry, titanium is used where weight must be reduced without sacrificing strength—for brackets, manifolds, ducts, or load-testing prototypes. 3D printing can combine several functions in one part (topology optimization, internal channels for cooling or fluids) and shorten development compared with machining from bulk stock.
Design work must account for build orientation, support strategy, and post-processing such as stress-relief or heat treatment, because they strongly influence final properties. Certified applications require validated processes and documentation, just like conventional manufacturing.
