Abstract

The invention discloses a resin tank for a DLP photocuring 3D printer capable of achieving quick film replacement and an assembling method thereof. The resin tank mainly comprises four parts including an upper end cover, an upper clamping plate, a lower clamping plate and a base; a polyperfluorinated ethylene propylene film is clamped between the upper clamping plate and the lower clamping plate and ejected into square through holes formed in the upper clamping plate and the lower clamping plate through a pressing frame of the upper end cover to be tensioned, the tensioned film can be well released from cured resin through the elasticity of the film in the printing process, and different printing precision requirements can be met by adjusting the tensioning degree of the film. According to the resin tank, a threaded fastener is not used in design, the polyperfluorinated ethylene propylene film can be quickly replaced and adjusted to the film tensioning degree, operation is more convenient, and the efficiency is improved.

Description

technical field [0001] The invention relates to components for a DLP light-curing 3D printer, in particular to a resin tank for a DLP light-curing 3D printer capable of quickly changing the film and an assembly method thereof. Background technique [0002] The working principle of the DLP light-curing 3D printer: For some liquid resins with photosensitive properties, the digital light processing (DLP) technology is used to realize the layer-by-layer curing of the resin, and finally form a 3D model. This method is surface exposure molding, which can print a whole layer of patterns at a time, with fast speed and high molding quality. [0003] The DLP light-curing 3D printer is mainly divided into two parts. The software part is used to process the model, slice the model, convert it into a plane picture and input it into the DLP imaging system. The hardware part receives the model data, prints layer by layer and finally manufactures the required model. The hardware part is ma...
