3D printing method and 3D printing equipment for realizing printing method

Abstract

The invention belongs to the technical field of 3D printing, and particularly relates to a 3D printing method. The 3D printing method is mainly used for 3D printing of medical orthopedic implants. According to the method, hydroxyapatite and adhesive are adopted as a printing material, the printing material is sprayed to obtain a layered printing material, then infrared thermosetting forming is carried out, a model is obtained after layer-by-layer printing, firstly, the adhesive is subjected to high temperature gasification through degrease treatment, a plurality of micropores are left in the model after the adhesive is subjected to high temperature gasification, and finally, a sample with a micropore structure is obtained after carrying out high-temperature sintering for a certain period of time. Personalized design is carried out on the sample according to actual conditions through a 3D printing technology to obtain the required orthopedic implants, the production and manufacturing cost of the orthopedic implants is reduced, the technical bottlenecks that common families cannot afford the orthopedic implants due to high price caused by the fact that when an titanium alloy is adopted to print the orthopedic implants at present are broken through, and the 3D printing method is of extraordinary significance in the medical field. The invention further provides 3D printing equipment for realizing the printing method.

Description

technical field [0001] The invention relates to a 3D printing method and a 3D printing device for realizing the printing method, which are used for 3D printing of medical orthopedic implants and belong to the technical field of 3D printing. Background technique [0002] The working principle of 3D printers is basically the same as that of traditional printers. They are composed of control components, mechanical components, print heads, consumables and media. Modeling with modeling software, and then "partitioning" the built 3D model into layer-by-layer sections, that is, slices, so as to guide the printer to print layer by layer. 3D printers mainly design a complete three-dimensional model on the computer before printing, and then print it out. [0003] At present, 3D printing technology has been widely used, and the commonly used 3D printing technologies are as follows: [0004] 1. FDM (abbreviation of "Fused Deposition Modeling") technology: [0005] FDM technology is t...

Problems solved by technology

However, in practical application, due to the high price of titanium alloy itself and the high manufacturing cost, the price of orthopedic implants made of titanium alloy is also very expensive, which is difficult for ordinary patient families to afford.
