Photosensitive material curing layer forming structure in 3D printing

Abstract

The invention discloses a photosensitive material curing layer forming structure in 3D printing. The photosensitive material curing layer forming structure is characterized by comprising a fixed seat,a lifting unit, a reaction unit and a container, wherein T-shaped clamping grooves are formed in the left side and the right side of the top end of the fixed seat; T-shaped clamping blocks are arranged at the left end and the right end of the rear side surface of the container; the T-shaped clamping blocks are clamped with the T-shaped clamping grooves in the top end of the fixed seat; a stirringunit is arranged on the rear side surface inside the container; an adding unit is arranged on the left side surface of the container; a protective unit is arranged at the top end of the front side surface of the container; fixed units are arranged on the two sides of the top end of the fixed seat; the lifting unit comprises a main motor, a connecting block, a lead screw, a movable block, a connecting rod, a mounting seat, a fixed block and a lifting plate; the connecting block is arranged in the middle of the top end of the fixed seat; and the lead screw is rotationally connected in a groovein the front side surface of the connecting block. The photosensitive material curing layer forming structure in 3D printing is simple to use, convenient to adjust, high in practicability and good informing effect.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a forming structure of a solidified layer of a photosensitive material in 3D printing.

[0002] The current basic structure of SLA and DLP3D printing is computer 3D modeling software, control panel, light source, photosensitive material (liquid state), square liquid container, printing object attached to the lifting plate; the basic principle is to solidify photosensitive material layer by layer to form an object ;Operation mode: computer 3D modeling slice, directly connected with light source equipment through control panel or computer, photosensitive material is placed in a square liquid container, the bottom of the liquid container is transparent, a small gap is left between the lifting plate and the square liquid container, and the gap is Liquid photosensitive material, when a sliced ​​image is projected through the light source and passes through the bottom of the square liquid container, the photosensitive material between the lifting plate and the square liquid container is excited, undergoes a polymerization reaction, solidifies and adheres to the lifting plate, when a After the layer is cured, the lifting plate is lifted, and a small gap will be formed between the cured layer and the bottom of the trough, and the next layer will continue to be cured, and the next layer will be attached to the previous layer. Layers are solidified and stacked to form the object to be printed. During the use of the current solidified layer forming device, the photosensitive material in the container lacks stirring measures, so as to prevent the photosensitive material from being too thick and impurities from adhering to the surrounding solidified layer, while moving up and down on the lifting plate It may lead to unstable situations, and in the process of using the photosensitive material, the addition of materials needs to be done manually, so when the material is too small, there will be a problem that it cannot be added in time, which will affect the working efficiency of the device
