Course Description
This course follows on a series of Additive Manufacturing (AM) classes beginning with DMT D053. The objective of this course is to present a comprehensive overview of industrial AM or 3D Printing DfAM principles. The course will cover implementation and operation options in industry production and rapid prototyping. Students will understand and be able to take full advantage of unique capabilities from AM competencies, DfAM methods, tools, and available processes. Typical DfAM methods or tools include topology optimization, design for multiscale structures (lattice or cellular structures), multi-material design, mass customization, part consolidation, and other design methods which can make use of AM-enabled features.
