摘      要：Since projection-based 3D bioprinting(PBP)could provide high resolution,it is well suited for printing delicate structures for tissue ***,the low crosslinking density and low photo-crosslinking rate of photocurable bioink make it difficult to print fine ***,an in-depth understanding of the is ***,a research framework is established for the analysis of printability during *** gelatin methacryloyl(GelMA)-based bioink is used as an example,and the printability is systematically *** analyze the photo-crosslinking reactions during the PBP process and summarize the specific requirements of bioinks for *** standard quantized models are established to evaluate 2D and 3D printing ***,the better strategies for bioprinting five typical structures,including solid organs,vascular structures,nerve conduits,thin-wall scaffolds,and micro needles,are presented.
