Model cleaning device based on photocuring 3D printing

Abstract

The invention discloses a model cleaning device based on photocuring 3D printing. The model cleaning device comprises a shell, a cleaning mechanism and a material storing table, wherein one side of the shell is opened and a door is arranged at the opening; the top end of the inner wall of the shell extends downwards to form a mounting part; a mounting groove is arranged above the mounting part; the cleaning mechanism comprises a water pump, a flow divider, a liquid inlet pipe, a liquid outlet pipe and an impeller; the water pump and the flow divider are both arranged at the bottom end in the shell; a liquid inlet of the water pump is connected with a pipeline and extends to the bottom end in the shell; a liquid outlet of the water pump is connected with the flow divider through the pipeline; the impeller is arranged in the mounting groove and is rotatably connected to the mounting part through a pivot at the bottom; a cover plate is detachably and fixedly connected to the upper openingof the mounting groove; a liquid discharge hole is formed in the center of the impeller; and the liquid discharge hole penetrates through the impeller and extends into the pivot. According to the model cleaning device based on photocuring 3D printing, the traditional manual cleaning is replaced by equipment cleaning, so that the cleaning process is more convenient and fast, the working efficiencyis greatly improved, and the cleaning effect is more perfect.

Description

technical field [0001] The invention relates to the technical field of 3D printing auxiliary equipment, in particular to a model cleaning device based on photocuring 3D printing. Background technique [0002] SLA3D printer, also known as light-curing 3D printer, is a 3D printing device that uses the principle of stereolithography technology. It is a very important process technology in the molding process of 3D printing technology. [0003] Use a laser with a specific wavelength and intensity to focus on the surface of the photocurable material (the material is mainly a liquid photosensitive resin), so that it is solidified sequentially from point to line, from line to surface, and completes a layer of drawing work, and then the lifting platform moves in the vertical direction The height of one layer is then solidified into another layer, so that layers are superimposed to form a three-dimensional entity. [0004] SLA is the earliest practical rapid prototyping technology. ...

AI Technical Summary

Problems solved by technology

[0006] 1. The manual cleaning process is cumbersome and the cleaning efficiency is low;

[0007] 2. Shaking the container manually during the cleaning process makes the alcohol splash, resulting in pollution of the operator and the operating environment and waste of alcohol;

[0009] 4. Cleaning depends on manual adjustment of the cleaning angle. The cleaning is not sufficient. After further curing and molding, the excess resin at the corners will change the shape and structure of the model, and the accuracy of the model will be seriously affected. As a result, the SLA printer cannot take advantage of the high printing accuracy.
