Ceramics particles are used to investigate the effect of the part size on the shrinkage percentage, the apparent, and the relative density of the printed part in the Binder Jetting 3D printing process. Four different shapes including cylinders, rectangular blocks, cones, and spheres of different sizes are printed at 100 %, 75%, and 50 % core saturation limits at 0 and 10 second delay using a binder jetting 3D printer. After the fabrication process, the parts are de-powdered and dried, the binder is cured at 35°C for 6- 8 hours then the parts are sintered. The shrinkage percentage, the apparent, and the relative density of the printed parts are calculated after the sintering process for each geometry at two different sizes. We use ceramics powder of 50% crystalline silica (quartz), 25% kaolinite, and 25% of potassium feldspar. The binder consists of 8% Diethylene glycol, 2% Surfactant, and 90 % water.
