Part Design and Topology Optimization for Rapid Sand and Investment Casting available in PDF, EPUB and Kindle. The integration of additive manufacturing into traditional metal casting provides a wide range of rapid casting solutions. One important motive for rapid casting is additive manufacturings ability to create highly complex objects without any fixture or tooling requirements. Such advantages provide great design freedom for the geometry of cast metal parts. The objective in this thesis is to explore the part design opportunistic and restrictions of two rapid casting processes: (1) sand casting with 3D Sand Printing-fabricated molds and (2) investment casting using material extrusionfabricated wax-like patterns. Knowledge-based design guidelines are developed for both of these rapid casting processes through novel integration of topology optimization with design for casting and design for AM principles. For each process, a case study is conducted in which a mechanical metal benchmark is topologically optimized and redesigned following the proposed design rules. The redesigned parts are successfully cast and demonstrate improvements in mechanical performance and weight reduction.
