3D bioprinting has been developed as a promising technology in a wide variety of biomedical applications.However,the successful implementation of bioprinting is still heavily restricted by the relatively narrow range of printable and biocompatible materials.Recently,many comprehensive reviews of the main bioprinting methods,commonly used bioprinting materials and the trending bioprinting applications have been carried out.In this review,we focused on the trends in the development of materials for 3D bioprinting.The significance and recent advances of ECM-based materials,multi-material and stimuli-responsive materials for bioprinting were sum-marized successively.Moreover,the challenges in current studies and future perspectives of materials for 3D bioprinting were discussed.
