Investigation of Highly Concentrated Calcium Phosphate Suspensions for Forming Bioceramic with Complex Architecture

Abstract

The rheological properties of highly concentrated calcium phosphate suspensions for producing bioceramic with complex shape by means of slip casting and 3D-printing were investigated. Macroporous bioceramic with gyroid architecture was prepared by casting water slips into polymer molds with gyroid geometry, which were fabricated by thermal-extrusion and stereolithographic 3D-printing. The limitations of this technology in reproducing fine details as compared with direct 3D-stereolithography of ceramic suspensions are indicated.
