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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
