Abstract:
1. An artificial bone forming method by a powder lamination method, comprising the steps of: (a) forming a powder bone material having biocompatibility, and hardening by hydration, into a flat powder layer; (b) jetting an aqueous solution having biocompatibility to a portion of the flat powder layer in order to harden by hydration the portion jetted by the aqueous solution; (c) repeating steps (a) and (b) in order to form, by lamination, a specified artificial bone of a predetermined three-dimensional structure in which the hardened portions are connected to each other; and (d) after step (c), discharging a gas contained in the artificial bone to further reinforce the hardened portions by a reaction using a change in pressure.
