The synthesis method of amorphous hydrated calcium phosphates using ion exchange was developed. Stable and homogeneous suspensions based on coloured CPP powders and light-curing monomer suitable for stereolithographic printing were obtained. Macroporous ceramic materials with a predetermined architecture were created by means of stereolithographic printing from suspensions based on coloured CPP powders and light-curing monomer. The properties of the suspensions (viscosity, photosensitivity, critical energy of polymerization) were explored. It was showed that the variation of the photosensitivity of suspensions by changing of the colour of the CPP powder sufficiently improves the resolution of stereolithographic printing. Ceramic materials with high osteoconductive properties were obtained using of the stereolithographic printing as a method of moulding of prefabricated ceramic units. Created porous ceramics based on calcium pyrophosphate have good resorbability and osteoconductivity and are suitable for using in medicine.
