Problems solved by technology

Therefore, the current LCD-type 3D printer has a cumbersome optical path system. In order to maintain the maximum uniformity and effective illumination area of ​​the light emitted by the light source, the space in the vertical direction of the 3D printer has to be occupied, resulting in an increase in the size of the 3D printer. large, increased manufacturing costs

Abstract

The invention provides a light source used for improving the photocuring contrast ratio. The light source comprises a substrate, a reflection bowl arranged on one side of the substrate and a light-emitting element arranged on the substrate and located at the focal point of the reflection bowl; in addition, the invention provides a resin pool adopting the light source; the resin pool comprises a transparent bottom wall, a peripheral wall arranged on the bottom wall and the light source arranged on the outer portion of the bottom wall; and the invention further provides a photocuring 3D printer adopting the light source or the resin pool. The light source, the resin pool and the photocuring 3D printer are short and concise in optical path, a large amount of internal space of the 3D printer cannot be occupied, and miniaturization and family orientation of the 3D printer are facilitated. In addition, the illumination intensity, light uniformity, the parallelism depth and the photocuring contrast ratio of the light source, the resin pool and the photocuring 3D printer are obviously improved, and energy sources can be more effectively used.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a light source for improving photocuring contrast, a resin pool using the light source, and a 3D printer including the resin pool. Background technique [0002] In 3D printing technology, photocuring rapid prototyping technology is more common, which uses liquid photosensitive resin (UV) to undergo polymerization reaction under light, and irradiates the light source according to the cross-sectional shape of the solid to be cured, so that the liquid photosensitive resin gradually After the layers are cured and formed, they are accumulated and superimposed, and finally a solidified entity is formed. [0003] At present, some light-curing printers use LCD liquid crystal display unit to display the cross-sectional pattern of the object to be printed, and then use light source to irradiate the LCD liquid crystal display unit. After the light passes through the LCD display unit, the liquid p...
