| Abstract Scope |
Powder-based 3D printing is popular due to its ease of use and versatility. However, many powder-based methods utilize high power lasers which generate thermal shock conditions in ceramics. In this work, a novel approach of producing high density net-shaped prototypes using Subtractive Sintering (SS) and Solvent Jetting (SJ) is developed. Additive Manufacturing combined with Subtractive Sintering (AM-SS) is a five simple step process that produces reliable results. A zirconia dental crown with a density of 97% was fabricated. Advantages of this method include the ability to efficiently fabricate parts using any powder including nano-sized ceramics, the utilization of conventional furnace only to consolidate, and the elimination of the difficult debinding step. The conducted studies include a predictive finite element model for the evolution of the complex-shape powder assembly during the AM-SS process. The model is based on the continuum theory of sintering embedded in a finite element code. |
