Abstract

The invention provides a 3D printing process method and printing equipment of a polycaprolactone low-temperature material. The printing processing method of the polycaprolactone low-temperature material comprises the steps that a scanning instrument or design software is firstly used for obtaining a 3D printing model; then corresponding model processing software is used for processing the model and setting parameters, and a printing file of a corresponding format is guided out; before a model product is printed, whether printing equipment can work normally or not needs to be checked, and it is guaranteed that the equipment is all normal; after the model product starts to be printed, the printing process parameters need to be secondarily set; after printing is completed, the printed product is taken down and subjected to postprocessing; and finally through quality and appearance checking, the qualified printed product is finally obtained.

Description

technical field [0001] The invention belongs to the technical field of polymer material processing and application, and in particular relates to a 3D printing process of polycaprolactone low-temperature material. Background technique [0002] 3D printing technology is a rapid prototyping manufacturing technology that is gradually developing, and it is an environmentally friendly and personalized manufacturing technology. At present, the most widely used printing equipment is FDM printing equipment. Its basic principle is mainly based on polymer materials, using fused deposition modeling technology, and completing the structure and formation of objects by layer-by-layer printing and accumulation. The polymer materials used for 3D printing in the market today are mainly high-temperature materials, and there are relatively few researches and developments on low-temperature composite materials, and even less research on the printing and manufacturing process of low-temperature m...
