Problems solved by technology

[0002] Polylactic acid has the advantages of high strength, good biocompatibility, and biodegradability, but its brittleness and poor toughness limit its application. The traditional method of toughening polylactic acid is to combine polylactic acid with oligomers or The direct blending of elastomers to prepare polylactic acid composites can improve the toughness of polylactic acid composites to a certain extent, but sacrifices biodegradability and antibacterial properties

Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to an antibacterial 3D printing material for medical products. Background technique [0002] Polylactic acid has the advantages of high strength, good biocompatibility, and biodegradability, but its brittleness and poor toughness limit its application. The traditional method of toughening polylactic acid is to combine polylactic acid with oligomers or The direct blending of elastomers to prepare polylactic acid composites can improve the toughness of polylactic acid composites to a certain extent, but sacrifices biodegradability and antibacterial properties. Most medical supplies have high requirements on their degradable performance and antibacterial performance, so it is urgent to design an antibacterial 3D printing material for medical products to solve the problems in the prior art. Contents of the invention [0003] In order to solve the technical problems in t...
