Abstract

A method for producing a 3D printed bone graft and a 3D printed bone graft are proposed. The method comprises a) preparing a photocurable composite resin composition by mixing a photocurable biocompatible polymeric resin, comprising one or more monomers/oligomers and a photoinitiator, with a hydrolysable calcium phosphate-based ceramic material; b) manufacturing a 3D printed bone graft using the photocurable resin composition through 3D printing with a light-based 3D printing system; c) cleaning and removing uncured resin or particles from the 3D printed bone graft by ultrasonic rinsing in a solvent; d) providing consolidation to the 3D printed bone graft by: d1) sublimating liquid contained in the resin by freeze-drying the manufactured 3D printed bone graft; and/or d2) hydrolyzing the hydrolysable calcium phosphate-based ceramic material to calcium deficient hydroxyapatite (CDHA).
