Additive manufacturing in medicine, particularly for the replacement of bone tissue, continues to be an exciting topic. Previous manufacturing processes such as sintering ceramics have produced mechanically stable constructions but these have so far deviated greatly from the modulus of elasticity of the bone. Deformation in particular posed a major problem (0.5% for ceramics). By additive manufacturing with calcium phosphate cement (CPC), bone-like values in the range of 10-20% displacement and a similar compressive strength to compact bone could be achieved. We are pursuing different approaches in additive manufacturing; a few examples are shown to the right.
