| Abstract Scope |
Casting was a traditional manufacturing method for Co-Cr biomaterials to produce implants and partial dentures and the fabrication of complex geometry with overhang structure and internal microchannels is challenging when using traditional manufacturing methods. Binder jetting is a process of joining powdered materials using a polymeric binder followed by post-processing including curing and densification steps. Here, Co-Cr biomaterial is used to 3D-print parts with various print process parameters such as binder saturation and layer thickness followed by sintering process. Sintering temperature and holding time affect linear shrinkage, densification and pore evolution. A database of microstructure evolution such as grain and pore intercept length, pore separation, surface area per unit volume and number of pore sections per unit area will be developed to better understand sintering kinetics, microstructural evolution and, finally, sintering mechanisms of binder jetted Co-Cr biomaterials. |
