Zusammenfassung:	The invention discloses a 3D printing konjac glue gel stent, a preparing method and application. Konjac glue gel is methacrylated konjac glue gel. The preparing method includes the following steps ofmodifying a konjac glue gel raw material through methacrylic anhydride, conducting dialysis and freeze-drying to obtain methacrylated konjac glue gel powder, dissolving the methacrylated konjac glue gel powder in PBS with a photoinitiator to obtain hydrogel, combining the obtained hydrogel with chondrocyte for printing through a 3D-Bioplotter system, and then conducting ultraviolet crosslinking toobtain the konjac glue gel stent product. The stent combined with the chondrocyte has the potential for cartilage repair engineering. The 3D printing konjac glue gel stent has the effects of being good in biocompatibility, controllable in material performance, low in cost, wide in source and simple in operation. 本发明公开了一种3D打印魔芋胶水凝胶支架及制备方法和应用。该本发明为一种3D打印魔芋胶水凝胶支架及制备方法和应用，所述魔芋胶水凝胶为甲基丙烯酸酯化魔芋胶水凝胶。所述制备方法包括以下步骤：甲基丙烯酸酐改性魔芋胶水凝胶原料，透
