The industrial code – GW laser in metal 3D printing

Additive manufacturing (3D printing) of metal materials is in great demand in aviation, aerospace, navigation, vehicles, mold manufacturing, medical equipment and other fields. At present, the heat source used in the metal additive manufacturing process includes three high-energy beams of laser beam, electron beam, micro beam plasma and sintering heat input, etc., of which the laser beam is the most widely used high-energy beam heat source in the field of metal additive manufacturing. Compared with the electron beam and microbeam plasma heat source, the laser beam has the advantages of fine spot, low cost, and directional action to the specified material position, which can realize the instantaneous melting of metal materials and meet the requirements of fusion channel lapping and part forming.
