Abstract

The invention relates to the field of 3D printing, and discloses a 3D printing method. The 3D printing method includes the following steps: configuring a curing system and a mixing system, wherein the mixing system includes a photoinitiator and light conversion particles, and the curing The system includes a ceramic curing system or a resin curing system, or, the mixed system includes light conversion particles, and the curing system includes any one of a ceramic curing system and a resin curing system and a photoinitiator; the curing system is placed on the printing platform, and put the mixed system into the barrel of the printing device; lay the mixed system in the curing system through the nozzle of the printing device, and use high-energy ray equipment to emit high-energy rays to irradiate the curing system According to get the target model. In the invention, the mixed system is laid in a specific area and irradiated with high-energy rays to solidify the part where the mixed system is laid, thereby improving the printing accuracy.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing method. Background technique [0002] 3D printing can realize rapid prototyping of complex structural parts without the need for molds, which overcomes the shortcomings of traditional processes that are time-consuming and difficult to manufacture complex structural parts. Poor performance, anisotropy, large shrinkage, low forming efficiency and the need to set up support and other deficiencies. In recent years, photocuring integrated molding utilizes the penetration of light to transparent photosensitive resins to generate chemical reactions from the inside, overcoming the shortcomings of layered formation methods, but it is difficult to achieve deep molding of opaque materials such as ceramics. The related technology arranges a single or several ray emission arrays around the forming container and makes regular movements, dynamically adjusts according to the shape of th...
