The industrial SLA laser 3D printer comprises a rack and a workbench arranged in the rack, a hopper is embedded in the workbench, a Z-axis mechanism is arranged on the workbench, a net plate traylifting mechanism located above the hopper is arranged on the front surface of the Z-axis mechanism, a shuttle scraper mechanism is arranged between the two ends of the hopper, a laser assembly is arranged at the upper end of the rack, the laser of the laser assembly faces the hopper, and a cantilever operation box is further arranged on the rack. The industrial SLA laser 3D printer can be applied to the technical field of 3D printers.

Description

Technical field [0001] The invention relates to a 3D printer, in particular to an industrial sla laser 3D printer. Background technique [0002] SLA is "three-dimensional light curing molding". The industrial sla laser 3D printer uses a laser beam to outline the shape of the first layer of the object on the surface of the liquid photosensitive resin, then the production platform drops a certain distance, and then the cured layer is immersed in the liquid resin. Repeat until the printing takes shape. Finally, after the prototype is taken out of the resin, it is finally cured, and then polished, electroplated, painted or colored to obtain the required product. [0003] The key to 3D printing is to ensure the consistency between the printed parts and the modeling prototype, and the positioning accuracy is very high. SLA3D printing is the current advanced laser light curing technology, but it is difficult to ensure the positioning accuracy when installing and positioning the existing ...

Problems solved by technology

[0003] The key to 3D printing is to ensure the consistency of the printed parts and the modeling prototype, and the positioning accuracy is very high. SLA3D printing is currently the most advanced laser curing technology, but it is difficult to ensure the positioning accuracy when installing and positioning the existing equipment during printing, and the mechanism is complicated. , Debugging requires experienced professional operators; after each layer is printed, the base moves down and the resin needs to be replenished, it is difficult to ensure the flatness of the resin liquid level, the existing technology is to use a scraper to level the liquid level, but to process products of different sizes , the displacement distance of the scraper is constant, but when processing small-sized products, it is necessary to wait for the entire moving process of the scraper to complete the next layer of processing each time, which greatly affects the processing efficiency; in addition, the existing laser The beam passes through the vibrating mirror to outline the object on the surface of the liquid photosensitive resin, but the existing laser beam aperture is not adjustable and cannot be adjusted according to the accuracy requirements of the product
