Hardening composite materials based on calcium phosphates (hydroxyapatite, monocalcium phosphate monohydrate) and polymer binders (polyvinyl alcohol, polyvinylpyrrolidone) were obtained. It was found that the amount of brushite and tricalcium phosphate grows with increasing calcium acid phosphate content in the composition. The introduction of polymeric binders into the composition of hardening composite materials promotes growth of their mechanical strength and inhibition of structural-phase transformations of calcium phosphates at 800°C. Compositions based on 5% solutions of polymers and powders of hydroxyapatite or its mixtures with weight content 10 – 40% monocalcium phosphate monohydrate can be used as a consumable for 3D printing of calcium phosphate biomaterials and ceramic.
