| Abstract Scope |
Additive manufacturing (AM) allows the quick fabrication of advanced, near net shape ceramic parts. However, ceramics produced by AM typically require post processing sintering to densify the part to the desired microstructure. As the ceramic part densifies, its volume will shrink to minimize the overall surface energy. An understanding of this shrinkage is needed to predict the final part dimensions after the sintering process. In this work, we manufactured various geometries of open cell structured alumina parts using a UV resin based process and measured the change in dimensions pre and post sintering at multiple points over the surface of the part. The shrinkage vectors at each point were used to determine how the local geometry affects the sintering shrinkage. The application of these shrinkage measurements based on printed geometry will be discussed. |
