Abstract
The results of the formation of composite bone implants filled with magnetoelectric elements (MEs) magnetostrictor/piezoelectric by stereolithographic 3D printing are presented. Such implants are capable of generating local electric fields under the action of an external magnetic field, creating an additional electrical stimulus for bone tissue regeneration. CoFe2O4 was used as a magnetostrictive material, and BaNiO3, Na0.5K0.5NBO3, and BiFeO3 were used as piezoelectric materials. Magnetoelectric elements filled hydrogel matrix based on a photopolymerized polyethylene glycol diacrylate (PEGDA) monomer. The main problems of stereolithographic formation of macroporous composites are associated with very strong absorption of UV radiation (405 nm) by monomer suspensions, containing CoFe2O4 and BiFeO3 particles.
