Evidence Basis
Based on EOS Ti-6Al-4V Material Data Sheet (machine manufacturer). Laser parameters are manufacturer-recommended process windows; mechanical properties are as-built typical values from that manufacturer’s data sheet and may vary with heat treatment and build orientation.
Engineering Interpretation (titanium.blog)
(titanium.blog) DMLS parts are anisotropic: XY strength exceeds Z because layer bonding governs Z properties. As-built tensile (1080-1150 MPa) meets wrought Grade 5 minima but elongation (10-12%) is lower than wrought; specify stress relief/annealing and build-orientation reviews for load-bearing applications. Manufacturer data, not an absolute guarantee across all machines.
