Preparation of Si3N4 micro-granules with biocompatible sintering additives by freeze granulation and freeze drying. The main aim will be the preparation of micro-granules with designed macro and micro-porosity, defined strength after pre-sintering. These properties have to be preserved during the preparation of slurry for 3D printing of porous scaffolds using the direct-ink-writing process. The printed scaffolds will be sintered in nitrogen atmosphere. The final total porosity, pore size distribution and compressive strength of scaffolds will be characterized.
