Photocuring 3D printer and working method thereof

Abstract

A photocuring 3D printer is technically characterized by comprising a printer body; a printing material tank and a printing platform are arranged in the printer body; a control screen used for conducting digital control on a digital path of ultraviolet by means of controlling a digital program is further arranged in the printer body; a control panel is arranged under the printing material tank; a light source plate is arranged under the control panel; ultraviolet light sources are arranged on the light source plate in an arrayed mode; an oxygen permeation membrane is arranged at the bottom of the inner surface of the printing material tank. A working method of the photocuring 3D printer comprises the steps that when the ultraviolet light sources illuminate, digital control over the digital path of the ultraviolet is achieved through the digital program in the control screen, so that a required image is controlled to be projected according to the digital program; and the encoded image is projected to the bottom of the printing material tank, so that photosensitive resin in the printing material tank is cured, and finally the photosensitive resin is cured onto the printing platform. By the adoption of the technical scheme, the size of the photocuring 3D printer is small, the printing speed and the printing area are increased, the manufacturing cost is low, and large-scale popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of 3D printing devices, in particular to a light-curing 3D printer and its working method. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of additive manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic and other bondable materials. Three-dimensional objects are created by printing layers of adhesive materials. [0003] At present, the light-curing 3D printers in the prior art are mainly based on laser galvanometer and DLP digital light processing technology. The equipment manufactured by the two technologies is large in size and high in manufacturing cost, which is not conducive to large-scale promotion. Contents of the invention [0004] In order to solve the above problems, the present invention provides a photocuring 3D printer and its working metho...
