Embodiment Construction

[0051] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0052] The inventor found in the research that when each layer is printed, there is adhesion between the cured resin and the upper layer of printing body and resin pool film. In order to maintain the continuation of printing, that is, there is a need for Replenish the liquid resin, and the cured resin should be separated from the resin pool membrane as well as possible. If the separation force is too large, it may cause the current layer of prints to peel off from the previous layer of prints, resulting in printing failure or defects on the surface of the printed model. ; If the separation force is too small, the printing process can be carried out sequential...

Abstract

The invention relates to a photocuring 3D printer and a printing method. The photocuring 3D printer comprises a resin pool assembly, a component for accommodating a resin pool film and fixedly arranged relative to a resin pool, and a transparent adhesive layer; the resin pool assembly comprises the resin pool film and the resin pool for accommodating the resin; and the two sides of the adhesive layer are bonded to the resin pool film and the component. The photocuring 3D printer effectively solves the problem about the long printing cycle time, shortens the printing time and improves the printing efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of 3D printing, in particular, to a photocuring 3D printer and a printing method. Background technique [0002] In light-curing 3D printers, light in a special wavelength band excites the photosensitive resin from liquid to solid to form a cured print. [0003] When printing, the forming platform is lowered to the initial position, and the bottom surface of the forming platform is close to the resin pool film, and then a part of the light is controlled by the display screen, and this part of light is irradiated to the resin between the forming platform and the resin pool film. After the resin is cured There is adhesion to the bottom surface of the forming platform and the resin pool film. If the adhesion to the forming platform is greater than the adhesion to the resin pool film, the cured resin will bond with the resin when the forming platform is lifted upwards. The pool film is separated to form...
