PURPOSE The purpose of this study was to compare the linear sintering behavior of presintered zirconia blocks of various densities. The mechanical properties of the resulting sintered zirconia blocks were then analyzed. MATERIALS AND METHODS Three experimental groups of dental zirconia blocks, with a different presintering density each, were designed in the present study. Kavo Everest® ZS bla...
Additive manufacturing of metals by 3D printing polymeric filaments containing high loading metal powder, subsequent debinding, and sintering offers a potent alternative to the widespread beam-based processes. The binder is decisive component for successful fabrication process. This study presents development multi-component system filament-based 316 L stainless steel in various optimization st...
In this study, the effect of two types of SiC powders consist of SiC-1 (β-SiC) and SiC-2 (β-SiC+α-SiC) and also different values of CaO additive consist of 0, 0.4 and 0.8 weight percent on sintering behavior of sintered SiC with pressureless technique in Al2O3-Y2O3-CaO additive system was investigated. In all specimens, Al2O3:Y2O3 molar ratio was equal to 3:2 and all amounts of additive were e...
