A multi-laser automatic rehydration sla3d printer

Abstract

The invention discloses a multi-laser automatic rehydration sla3D printer, which comprises a casing, the inner side of the casing is fixedly connected with a bearing plate, the bottom surface of the bearing plate is movably connected with a laser head, and the top surface of the bearing plate is fixedly connected There are guide rails, and the front side of the guide rails is movably connected with a sliding connection and a lifting plate. The invention relates to the field of 3D printing equipment. The multi-laser automatic rehydration sla3D printer can judge the photosensitive resin reserve inside the rehydration tank through the support plate and straight tube and other devices, and through the scale at the bottom of the straight tube, which ensures the quality of the photosensitive resin and delays its deterioration. The pressure plate realizes the smooth supply of photosensitive resin in the process of liquid replenishment, which improves the product quality. The scraping of the scraper and scraper avoids the condensation and blockage of the photosensitive resin on the surface of the rubber pressure plate, reducing equipment failure. This solves the problem that the storage of photosensitive resin in the printer is unclear, ripples are easily generated during liquid replenishment, which affects product quality, and the liquid replenishment port is easily blocked.

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...
