Rapid Laminated Manufacturing for Metallic Parts Based on Resistance Welding Double-Station LOM

Abstract

The adhesive strength between the metallic sheets and the way to remove the waste are the key problems of the laminated object manufacturing (LOM) for metallic functional parts. To solve these problems, a novel resistance welding double-station LOM was presented in this paper with its basic principles and implementation approach introduced. With 302 stainless steel sheets of 0.1mm in thickness as the model material, the rapid laminated manufacturing for metallic parts was conducted. As a result the plastic rapid injection mold shows its diffusion welding effect between sheets up to complete combination and its strength is more than 600MPa. The surface of plastic product injected according to the mold reaches the standard in dimensional accuracy and surface finish. The experiment has proved that the resistance welding double-station LOM is an effective method of the direct rapid manufacturing for metal parts of high strength.
