Popis: Artificial bone implants are in relatively simple shapes for use mainly by cutting or manually. To produce a desired bone shape, we used tribasic calcium phosphate bone ash powder as the material and aqueous sodium chondroitin sulfate solution as the binder in inkjet powder-layered manufacturing. In experiments, we reproduced a rabbit femur with a precision of 0.6 mm and a minimum longitudinal hollow shaft 2 mm in diameter based on computed tomography data. We gave the brittle artificial bone a compressive strength of 3 MPa by dipping it in water and binder through its hydrate reaction.
