Abstract: The present invention relates to a method for manufacturing a bone graft material using 3D printing of a DLP system. The method includes (1) dispersing a powder material including calcium phosphate-based ceramics in a solvent; (2) recovering the calcium phosphate-based ceramics by removing the solvent from a solution in which the calcium phosphate-based ceramic material is dispersed in Step 1; (3) producing a photocurable resin composition by adding a binder resin including a crosslinking agent and a photoinitiator to the calcium phosphate-based ceramics obtained in Step 2; (4) performing 3D rapid prototyping on a bone graft material molded body from the composition for a bone graft material produced in Step 3 by 3D printing of a DLP system; and (5) debinding and sintering organic materials remaining in the bone graft material molded body subjected to prototyping in Step 4.
