Additive Manufacturing of Ti6Al4V with Wire Laser Metal Deposition Process

Additive manufacturing (AM) using wire as an input material is currently in full swing, with very strong growth prospects thanks to the possibility of creating large parts, high deposition rates, but also a low investment cost compared powder bed fusion machines. A versatile 3D printing device Direct Energy Deposition Wire-Laser (DED-W Laser) Precitec Coaxprinter station melt metallic filler developed build titanium parts by optimizing process parameters. The geometrical and metallurgical produced are analyzed. In literature, several authors agree define feed speed, travel laser beam power first-order parameters governing laser-wire deposition. This study shows relative importance these taking separately well their sequencing at start process. Titanium deposit obtained powers never explored bibliography (up 5 kW), speed up m.min -1 complete repeatability.
