From: In situ repair of bone and cartilage defects using 3D scanning and 3D printing
Process of 3D bioprinting and photopolymerization on chondral defect. Due to the influence of UV light of camera, the light was turned off when shooting video and photographs in one of the three printing process. Photopolymerization was taken at the end of printing. (A) Repair of chondral defect through in situ 3D bioprinting with m-HA hydrogel. (B) Exposure to UV light. (C–F) The color of m-HA hydrogel that was printed to repair the chondral defect was milky white before and after photopolymerization. The chondral defect was restored perfectly.
