Abstract: The present invention relates to a method for manufacturing a three-dimensional artificial scaffold, capable of providing an artificial scaffold made of only a pure bioceramic material, by forming a three-dimensional artificial scaffold using artificial scaffold slurry containing bioceramic fine particles as a main component and then sintering the artificial scaffold at a high temperature to remove foreign substances. The method of the present invention comprises the steps of: preparing artificial scaffold slurry containing a bioceramic material; heat-treating the prepared artificial scaffold slurry to give flexibility to the artificial scaffold slurry; discharging the heat-treated artificial scaffold slurry using a syringe such that the artificial scaffold slurry is deposited, and hardening the artificial scaffold slurry discharged for each layer using hot air, thereby preparing a three-dimensional artificial scaffold; and sintering the three-dimensional artificial scaffold prepared in the above step, thereby completing a three-dimensional artificial scaffold made of only the pure bioceramic material.
