Abstract

The invention relates to a preparing method of a 3D printing intelligent deforming material. The method aims at printing complex irregular shapes such as a gradient structure, a biology structure, a spiral structure and a microstructure, the method is precise and efficient, simple and easy to implement, and the 3D printing intelligent deforming material of a complex structure and with large deforming is prepared, and the method comprises following steps of firstly, preparing of polymer wires, and secondly, 3D printing of the intelligent deforming material. On the basis of the 3D printing technology, polyether-ether-ketone powder and a carbon fiber serve as the main material, through control design of the printing shape in the 3D printing process, the path can be programmed, the crossed angle between layers can be changed, the pre-deformed structure is more complicated and diverse, deforming is benefited due to being parallel to the printing path, the larger deforming and the deformingrestore rate can be obtained, through the preparing method, the machining step is simplified, production cost is saved, and machining efficiency is improved.

Description

technical field [0001] The invention relates to a preparation method of a deformation material, in particular to a preparation method of a 3D printing intelligent deformation material. Background technique [0002] Compared with the traditional processing mode of raw material removal, cutting and assembly, 3D printing is a "bottom-up" manufacturing method through material superposition. Through 3D printing manufacturing, without machining or any mold, parts of any shape can be directly generated from computer graphics data, without assembly, which can greatly shorten the product development cycle, and 3D printing saves materials, reduces the waste of raw materials and The production cost has been improved, and the productivity has been improved, which has made it possible to manufacture complex and precise structural parts that were previously unattainable under the constraints of traditional manufacturing methods. [0003] With the intensification of international competit...
