Multi-laser automatic liquid supplementing sla3D printer

Abstract

The invention discloses a multi-laser automatic liquid supplementing sla3D printer. The multi-laser automatic liquid supplementing sla3D printer comprises a machine shell, wherein a bearing plate is fixedly connected to the inner side of the machine shell, a laser head is movably connected to the bottom surface of the bearing plate, a guide rail is fixedly connected to the top surface of the bearing plate, and a lifting plate is movably and slidably connected to the front surface of the guide rail. The invention relates to the field of 3D printing equipment. According to the multi-laser automatic liquid supplementing sla3D printer, through devices such as the bearing plate and a straight pipe, the storage amount of photosensitive resin inside a liquid supplementing box can be judged through scales at the bottom end of the straight pipe, the quality of the photosensitive resin is guaranteed, and the deterioration of the photosensitive resin is delayed; the smooth supply of the photosensitive resin in the liquid supplementing process is achieved through a sleeve and a rubber pressing plate, and the production quality is improved; the condensation and the blockage of the photosensitive resin on the surface of the rubber pressing plate are avoided through scraping and sweeping of scraper blades and a scraper, and equipment failures are reduced; and the problem that the storage amount of the photosensitive resin of the printer is not clear, and ripples are prone to generate during liquid supplementing, so that the product quality is influenced, and a liquid supplementing openingis prone to block is solved.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a multi-laser automatic rehydration sla3D printer. Background technique [0002] SLA (Stereo Lithography Apparatus) technology is laser three-dimensional engraving technology, which is the crystallization of machinery, laser, photochemistry, software and control technology. Based on the principle that the photosensitive resin is solidified by ultraviolet light, the computer controls the laser to scan and solidify the liquid photosensitive resin layer by layer. The cured cross section of each layer is obtained by layering the 3D CAD model software of the part, until finally the physical prototype of the photosensitive resin is obtained. Light-curing rapid prototyping should have the highest precision and smoothest surface in 3D printing technology. [0003] In the actual printing process, as the position of the lifting plate carrying the product gradually increases, the inter...
