| Abstract Scope |
This presentation will focus on additive manufacturing enabling the fabrication of complex geometries with multi-functional properties for biomaterial and medical applications. Depending upon the desired manufacture-to-build requirements, process parameter predictions using dimensional analyses will be demonstrated. A range of process parameters permits tailoring of microstructures, defects, properties, and surface roughness. Interestingly, the actual design properties will significantly differ from reference values, so knowledge of the properties are important before fabrication begins. In addition, laser powder bed fusion permits dimensional accuracies as low as 20 microns, and depending upon orientations, approximately 200 microns of the finest dimensional control for geometric features such as corners and dimensional thicknesses. With the design requirements and processing conditions defined, fabrication of medical devices, lattice structures for cellular scaffold structures, and biomimetic structures for enhanced toughness and specific strength will be illustrated to explore the breadth and potential impact of AM on future biomaterials. |
