Ti-6Al-4V (wire-DED, Meltio Titanium 64)

Meltio Titanium 64 is a Ti-6Al-4V wire feedstock printed by wire-feed laser directed energy deposition, where a laser melts the wire into tracks built up layer by layer under inert gas shielding. Repeated melting and reheating give coarse columnar prior-beta grains elongated along the build direction with a fine lamellar alpha-beta structure inside, so properties differ between build directions. Deposits are near-net shapes with a wavy, rough surface and residual stress, and are normally stress relieved and machined to final dimensions. Typical uses are near-net preforms for machined aerospace and industrial parts, repair of titanium components, and adding features to existing parts. Every value on this page is read from Meltio's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
