There are currently numerous diseases such as cancer that require the removal of body structures such as the affected bone and cannot be restored back to the patient. In particular, in traumatology, there is a need for bone restitutions that were damaged or contaminated by cancer or an infection by new synthetic bones similar to those resected with the ability to integrate, bear load, and what is more important to give a quality of life to the patient by reducing health spending at the same time. For this reason, the GENCOR project aims to develop innovative production techniques, materials and design solutions aimed at generating restorations of body structures such as, for example, a section of the sacrum, but will also study the possibility of working in substitutes of other organs or structures of the body and in guidance systems for their implantation in subsectors with the greatest potential impact.
