| Abstract Scope |
There are two major limitations of current bone replacement techniques: inability to specify the shape of the graft and low mechanical properties. This often leads to a rejection of the implant, reoperation or removal. Current tissue engineering advances combined with recent advances in three–dimensional (3D) printing technologies have the potential to generate cell loaded bone grafts with specific architecture to increase implant success.
In this study, a custom-built binder jetting printer was used to produce complex shape ceramic scaffolds strong enough to mimic bone. With this printer and the subsequent sintering, a cubic sample with a density of 70% and strength of 113 MPa was produced. Additionally, a complex scaffold shape with final porosity of 50% and strength of 30 MPa was also achieved. The results of this study show the potential of ceramic materials, processed via 3D printing and sintering, as a more effective bone substitute. |
