| Summary: | Calcium phosphate cements (CPCs) could be employed as synthetic bone graft substitutes or scaffolds for tissue engineering allowing the fabrication of more complex geometries and the customization of the implants mainly due to the possibility to be molded.1 Moreover, the use of additive manufacturing technologies at low temperatures such as 3D printing allows the fabrication of pieces with enhanced performance over traditional techniques.2,3 Usually, the obtained pieces have low mechanical strength; however, the use of polymeric additives such as acrylamide (AA) and ammonium polyacrylate (PA), could reinforce the system through in situ polymerization and increase the mechanical properties of the final piece.4
