Abstract
Development of additive manufacturing (AM) from three dimensional printers with ability of producing parts having no need for
tooling continue to wax stronger in the manufacturing field. Laser metal deposition, a technique in AM is usually employed to
create solid components from model of computer aided design (CAD). Feeding powder supported by shielding gas employed by
this technique, is injected into a melt pool produced by accurately focused laser beam on a substrate. This paper discusses some
of the AM technologies available, review on laser metal deposition of titanium aluminide on other metals and alloys, relationship
between the processing parameters and structural and mechanical properties
