Zusammenfassung:	The invention discloses a degradable 3D printing wire material based on modified black talc as well as a preparation method and application of the degradable 3D printing wire material. The printing wire material is prepared from the following components in parts by weight: 100 parts of polylactic resin, 0.1 to 12 parts of terminal group ethylene glycol modified polylactic acid, 1 to 35 parts of modified black talc and 0.1 to 2 parts of coupling agent. According to the invention, the black talc containing natural organic matters on the surface is modified and is used as a filler, so that the material cost is reduced, the compatibility with PLA can be increased based on the natural organic matters contained on the surface, and meanwhile, the system compatibility is further improved by adding the terminal group ethylene glycol modified polylactic acid. 本发明公开一种基于改性黑滑石的可降解3D打印丝材及其制备方法与应用。所述打印丝材按重量份数计，包括以下组分：聚乳酸树脂100份、端基乙二醇修饰聚乳酸0.1-12份、改性黑滑石1-35份，偶联剂0.1-2份。本发明通过对表面含天然有机物的黑滑石进行改性，并以其作为填充剂，既降低材料成本，也可以基于其表面含有的天然有机物增加其
