Ti-6Al-4V ELI (Grade 23) (L-PBF, 3D Systems LaserForm Ti Gr23 (A))

3D Systems LaserForm Ti Gr23 (A) is a grade of Ti-6Al-4V ELI (Grade 23) powder made for laser powder bed fusion, in which a laser melts the titanium alloy powder layer by layer under inert gas. Rapid solidification gives a fine martensitic microstructure in columnar prior-beta grains along the build direction, so as-built parts are strong but less ductile and somewhat anisotropic. Parts need supports and carry high residual stress, so they are stress relieved before removal from the plate and are often hot isostatically pressed and machined to close porosity, improve fatigue life and remove the rough surface. Uses include aerospace brackets and lattice-structured orthopedic parts.
