Abstract

The invention relates to the technical field of 3D printing, in particular to a 3D printing charging tray and an exposure stripping technology of the 3D printing charging tray. The 3D printing charging tray comprises a base, a releasing film, light-transmitting glass and a clamping plate. The base is provided with a first groove and a second groove, the first groove and the second groove penetratethrough the top end face of the base, the light-transmitting glass is arranged in the first groove, the upper surface of the light-transmitting glass is higher than the bottom wall face of the secondgroove, the release film is arranged on the top end face of the base and is pressed between the base and the clamping plate, a first cavity is defined by the release film, the inner wall of the firstgroove and the light-transmitting glass, a second cavity is defined by the release film and the inner wall of the second groove, and the two cavities communicate. During exposure, the cavities are pumped to from negative pressure, the release film can be tightly attached to the glass, bubbles do not exist between the release film and the glass, tensioning of the release film is achieved, the printing precision is improved, when the release film is released, air is inflated to the cavities, the cavities form positive pressure, the release film and the light-transmitting glass are stripped, andthe aim is easily achieved.

Description

technical field [0001] The present application relates to the technical field of 3D printing, in particular to a 3D printing tray and an exposure stripping process for the 3D printing tray. Background technique [0002] At present, with the advancement of light-curing 3D printing technology, light-curing 3D printers are also developing towards industrial machines. As a tray carrying photosensitive materials, the professional requirements are getting higher and higher. The more common ones are the film-coated trays made of silica gel and the stretch film trays that use the structure to tension the release film. [0003] Common film-coated trays are composed of structural parts, light-transmitting glass, silica gel, and release film. Use glue to fix the light-transmitting glass on the structural parts and achieve a sealing effect. Pour the adjusted liquid silica gel onto the light-transmitting glass and scrape it flat and wait for it to solidify naturally. Finally, stick t...
