The study of the rheological properties of highly concentrated calcium phosphate suspensions for the creation of bioceramics of complex shape by slip casting and 3D printing has been carried out. Macroporous bioceramics with a gyroid architecture were made by casting water slips into polymer molds with a gyroid geometry, produced by thermal extrusion and stereolithographic 3D printing. The limitations of this technology in the reproduction of fine details are shown in comparison with direct 3D stereolithography of ceramic suspensions.
