Photo-curing 3D printer and resin tank assembly and printing method thereof

Abstract

The present disclosure relates to a photocuring 3D printer, a resin pool assembly thereof, and a printing method thereof. Wherein, the resin pool assembly includes a pool body (1) for containing resin materials and a light-transmitting pool bottom and a mounting seat (4) for detachably installing the pool body (1), in the pool body ( 1) and the mounting seat (4) is provided with an OLED screen (2). Since the self-luminous OLED screen has the advantages of fast response speed, light emission with a simple driving circuit, and simple manufacturing process, and in terms of display, the OLED screen has high brightness, fast response speed, stable image and high resolution. Therefore, , the light-curing 3D printer and its resin pool assembly of the present disclosure use an OLED screen to provide a light source, avoiding complicated optical path settings, and the 3D printing method performed by using the light-curing 3D printer makes the manufacturing cost relatively low, and reduces The delay in printing improves the photocuring efficiency and correspondingly improves the printing efficiency.

Description

technical field [0001] The present disclosure relates to the field of 3D printing, in particular, to a light-curing 3D printer, a resin pool assembly, and a printing method thereof. Background technique [0002] In 3D (three dimensional) printing technology, photocuring rapid prototyping technology is more common, which uses liquid photosensitive resin (UV) to undergo polymerization reaction under light, so that the light source can be cured according to the cross-sectional shape of the 3D printing object to be cured. After irradiation, the liquid photosensitive resin is cured layer by layer and then accumulated and superimposed, finally forming a cured 3D printing object. [0003] Currently, photocuring rapid prototyping devices based on the above principles mainly include a selective laser curing device (SLA, also known as a stereolithography device) and a mask photolithography device (DLP). [0004] Among them, the selective laser curing device uses a laser with a specif...

Problems solved by technology

[0006] In addition, whether it is a selective laser curing device or a mask photocuring device, it has a complex optical path, resulting in a long delay during printing, which reduces the curing efficiency

[0007] In order to increase the speed of light curing, Carbon3D in the United States invented a continuous light curing technology (CLIP) based on DLP. Although this technology can increase the printing speed, the manufacturing cost is high, and the price of this 3D printer reaches tens of thousands of dollars.

[0008] In addition, if the light curing speed is increased by selecting a light source with higher intensity, the heat released by the resin at the bottom of the photosensitive resin pool will increase during curing, thereby reducing the service life of the resin pool
