Outline of Final Research Achievements

Additive manufacturing technology is a processing method that enables complex three-dimensional structures to be formed, and processing of resins, metals and ceramics is commercially feasible. However, the processing of composite structures of resin and metal has not yet been realised. This study aimed to establish multi-material AM (MMAM) by combining laser sintering, which is also popular as an additional manufacturing technology for plastic end parts, with LDS, which is a manufacturing technology for plastic moulded parts with metal interconnections on the surface and MIDs. By mixing a copper compound with common laser sintering powders, a technique was established to produce components made of polyamide, and MMAM of polyetheretherketone with a high melting point and high strength was also made possible.
