High-precision continuous 3D printer and printing method thereof

Abstract

The invention discloses a high-precision continuous 3D printer, and relates to the technical field of 3D printing. The high-precision continuous 3D printer comprises a machine body, a vertical rod anda transverse rod fixedly connected between the two sides of the inner wall of the machine body. A sliding block is slidably connected to the surface of the transverse rod; a multi-color printing assembly is arranged on the top of the machine body, and the multi-color printing assembly comprises a material box; a vertical plate is fixedly connected between the top and the bottom of the inner wallof the material box; a fixed groove is formed in the vertical plate; a curved bar is rotatably connected between the two sides of the inner wall of the material box through a bearing; and a worm sleeve is fixedly connected to the position, located in the fixed groove, of the surface of the curved bar. According to the high-precision continuous 3D printer and the printing method thereof, multi-color or mixed-color printing of products can be achieved, meanwhile, the problem that colored photosensitive resin liquid is prone to solidification and impurity precipitation in the storage process canbe solved, a foundation is laid for irradiation curing work of a UV lamp, and meanwhile the quality of the printed products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a high-precision continuous 3D printer and a printing method thereof. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files and uses bondable materials such as powdered metal or plastic to construct by layer-by-layer printing. Object technology, 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacturing of some products. There have been printings using this technology. components, the technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineeri...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-precision continuous 3D printer and its printing method, which solves the problem that most of the materials printed by the existing 3D printer are of a single color, and then dyed later, which is time-consuming and labor-intensive and prone to dyeing failure. At the same time, the dyeing liquid is prone to solidification before coloring, which is likely to affect the quality of subsequent printing products
