Abstract

The higher life expectancy and increased sedentary lifestyle increased the incidence of bone diseases and the number of patients requiring biomedical implants. In this context, calcium phosphates (CaP) play an important role since they are biocompatible, resorbable and bioactive. These materials have been used as dense blocks, granules and scaffolds. The last one had porous structures that allow cells to develop throughout the pores. 3D printing, a technique that permits the production of customized pieces with controlled porosity, could process these materials. The aim of this proposal is to fabricate Si,Sr co-doped calcium phosphate scaffolds using the BCN3D+ Reprapbcn, a machine that prints 3D parts by injecting pastes ("inks"). (AU)
