MULTI-SCALE TOPOLOGICALLY OPTIMIZED COMPONENTS MADE BY CASTING AND ADDITIVE MANUFACTURING

摘要

Three distinctive styles of component manufacturing were studied in this work. The following conclusions can be made from the findings 1. The use of wax patterns in a conventional investment casting process is a viable way to produce topologically optimized complex components, as the process uses lost patterns 2. Sand mould printing is one conceivable way to achieve complex geometries in much larger scales 3. Mixing of different production methods such as casting, machining, welding and additive manufacturing of metal parts is possible using suitable materials
