Abstract

The invention relates to the technical field of 3D printing forming and provides a 3D printing method of a metal ceramic composite material. The 3D printing method of the metal ceramic composite material aims to solve the problem that printing of a metal material and a ceramic material is very difficult to complete through the same 3D printing process due to the characteristics of the material. The 3D printing method of the metal ceramic composite material comprises the following steps of S1, respectively performing ball milling on metal powder and ceramic powder, and screening and collecting to obtain metal micro-powder a with the particle size of less than 60 microns and ceramic micro-powder b with the particle size of less than 45 microns; S2, mixing the metal micro-powder a and the ceramic micro-powder b to obtain powder A, adding photosensitive resin to the powder A according to a ratio of 1: 1.6, and uniformly mixing the photosensitive resin and the powder A to form printing slurry B; and S3, feeding the printing slurry B into a raw material bin of photocuring 3D printing equipment, inputting a set printed piece model, enabling the photocuring 3D printing equipment to start printing, and firstly forming a green body C of a printed piece. The 3D printing method of the metal ceramic composite material is particularly suitable for 3D printing of the metal ceramic composite material, and possesses higher social use value and application prospect.

Description

technical field [0001] The invention relates to the technical field of 3D printing and molding, in particular to a 3D printing method of metal-ceramic composite materials. Background technique [0002] 3D printing is a new type of workpiece processing and manufacturing technology, which is characterized by sequential additive manufacturing from scratch in the manufacturing process. Compared with traditional manufacturing methods, the 3D printing technology of additive manufacturing can be used without traditional molds and fixtures. In the case of arbitrarily complex and functional three-dimensional entities, it has higher flexibility and usability. [0003] 3D printing technology to form and prepare workpieces has the advantages of fast forming speed, good performance, high precision, and the ability to form complex structural products, which is accepted by people and applied in various fields. In the existing 3D printing technology, ceramic printing generally prepares slu...
