The invention discloses an elastomer PLA/TPU 3D printing wire and a preparation method thereof, and relates to a printing material. The purpose of the present invention is to provide a 3D printing polymer material with good toughness. The technical scheme of the present invention is as follows: 1. The formula according to the weight percentage is: PLA 84-98%, TPU 1-10%, compatibilizer 1-5%, (fluoro)polymer processing aid PPA 0.01-1%, anti- Oxygen agent 0.1 to 0.5%. The invention improves the interfacial adhesion between PLA and TPU by using an elastomer compatibilizer, and adds a (fluoro)polymer processing aid PPA to improve or even eliminate the wire drawing phenomenon caused by the accumulation of PLA/TPU 3D wire in the nozzle of the 3D printer. A flexible and easy-to-print 3D printing filament. |
