Filling system for photosensitive material and 3D printer adopting filling system

Abstract

The invention discloses a filling system for a photosensitive material and a 3D printer adopting the filling system. The filling system comprises a platform component and a packing box, wherein the platform component comprises a first platform, a raw material tank and a second platform; the first platform is horizontally arranged; the second platform is capable of moving up and down in the raw material tank; an opening at the upper end of the raw material tank is aligned with the upper surface of the first platform; an edge of the second platform is in sealing contact with an inner side wall of the raw material tank; the packing box is arranged above the first platform; an opening end of the packing box is in sealing contact with the upper surface of the first platform; the packing box andthe first platform can move relatively along the horizontal direction; when the first platform and the packing box are relatively moved to a first position, the photosensitive material flows out fromthe packing box to the second platform and is free from splashing phenomenon; when the first platform and the packing box are relatively moved to a second position, the photosensitive material is sealed in the packing box. Thus, the packing speed of the photosensitive material can be increased by increasing the relative moving speed of the first platform and the packing box, and the system running is stable.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a photosensitive material filling system and a 3D printer using the system. Background technique [0002] A conventional photosensitive 3D printer is composed of a projector or a laser vibrating mirror structure, a raw material tank for placing liquid photosensitive resin, and a vertically moving component table and other transmission mechanisms; its working principle is to project ultraviolet light to the photosensitive resin through a projector or laser vibrating mirror structure. The image makes the liquid photosensitive resin solidify due to the polymerization reaction of ultraviolet light, and the motor drives the screw to rotate to make the component table move up or down continuously to form an object. Currently commonly used photosensitive 3D printers have a printing platform ascending type and a printing platform descending type. Among them: in the ri...

Problems solved by technology

Among them: in the rising printing platform, the filling of photosensitive resin material is mainly driven by the surface tension of the photosensitive material itself, and the filling speed is slow, which seriously affects the printing efficiency

In the descending type of printing platform, the liquid photosensitive resin is made even and uniform through the movement of the scraper system on the surface of the liquid. If the scraper system moves too fast, it will easily cause the liquid to splash and sway, which will seriously affect the printing efficiency.

[0003] Therefore, how to solve the problem of low printing efficiency of existing photosensitive 3D printers due to the slow filling speed of raw materials has become an important technical problem to be solved by those skilled in the art
