The rapid development of modern industry requires creating new types of biomaterials with enhanced performance characteris- tics, including structural ones. The main methods for producing biomaterials based on calcium phosphates do not allow obtaining products with a complex architecture, for example, with internal pore channels with different and complex direction with a diam- eter of 100 microns. Modern methods of additive technologies allow creating products with a tailored space inside the structure. Among the wide variety of rapid prototyping methods (3D printing), the most promising approaches are stereolithography of filled photo- sensitive suspensions and robocasting of highly concentrated pastes. The stereolithography method has the best lateral resolu- tion, which allows producing miniature products, and robocasting allows to create products of any size with high-speed. This talk tries to discuss several strategies for the additive fabrication of different types of personalised implants for bone tissue regeneration and the importance of pore architectonics for its osteoconductive properties.
