The invention relates to photopolymerisable composite biomaterials for 3D printing of implants, formed by biocompatible mixtures of polymers derived from urethane dimethacrylate (UDMA), tetrahydrofurfuryl methacrylate (THFMA), methyl methacrylate (MMA), methyl polymethylmethacrylate (PMMA), 2-hydroxyethyl methacrylate (HEMA), neopentylglycol diacrylate propoxylate(NPGDP), vinyl acetate (VAc) and polyvinyl acetate (PVAc) combined with photoinitiators and mixtures of nano and microparticles of inorganic composites of hydroxycarbonate phosphates of calcium and titanium oxide. The mixtures are used as a printing material in the 3D printers which are operated by means of photopolymerisation using ultraviolet-visible light (stereolithography) and allow the exact reproduction or printing of virtual solid images of parts of tissues and organs made by means of computer-assisted design (CAD) or generated or reproduced from medical images such as CAT, NMR and others. The products obtained when polymerised with ultraviolet-visible radiation have suitable mechanical and biocompatibility properties for producing implantable medical devices by means of stereolithography 3D printing.
