Abstract

The invention discloses a 3D printing method of TPU 9370AU plastic particles. The 3D printing method comprises the steps that a target three-dimensional CAD model is layered through a computer, and the section information is processed; then, the section data are input into a 3D printer with an APF technology; and droplets generated by melting TPU 9370 AU plastic particles are stacked layer by layer through the 3D printer according to the section data, so that a TPU 9370 AU product with the designed structural shape is obtained. According to the 3D printing method, domestication of the TPU 9370AU plastic particles and precision forming of additive manufacturing are achieved, and the closed-loop system construction from product design to manufacturing of the TPU 9370AU plastic particles special for the APF technology to the product printing and forming process is achieved; intermediate links are omitted, and the material cost is saved; and the batch production is achieved, and the research and development speed and the industrialization speed are increased.

Description

technical field [0001] The invention relates to a 3D printing method of TPU9370AU plastic particles, belonging to the field of 3D printing. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, combines computer-aided design, material processing and molding technology, based on digital model files, and uses software and numerical control systems to combine special metal materials, non-metal materials and medical biomaterials. , According to extrusion, sintering, melting, photo-curing, spraying and other ways to accumulate layer by layer, the manufacturing technology of manufacturing physical objects. Compared with the traditional processing mode of raw material removal-cutting and assembly, it is a "bottom-up" manufacturing method through material accumulation, starting from scratch. This makes it possible to manufacture complex structural parts that were restricted by traditional manufacturing methods in the past. [0003] APF (ARBURG P...
