Problems solved by technology

Furthermore, in 3D printing work, for example, in order to increase the print size, the projected images of more than two projectors need to be stitched together. However, the influence of optical lens aberration and system assembly tolerance easily makes image stitching difficult
The conventional stitching method is to first overlap the images and correct the distortion of the images, and then mix the overlapped images to make the brightness uniform, but this method is not only time-consuming and difficult to improve the adjustment accuracy, but also uses image blending to stitch , the overlapping images tend to become blurred, so it is difficult to meet the quality and speed requirements of 3D printing

Abstract

The system includes a first projector, a second projector and a molding zone; the molding zone can accommodate a photocurable material and includes a first area and a second area; the first projectorcan project a first image to the first area; the second projector can project a second image to the second area; the area where the first image and the second image are overlapped with each other is only a splicing line; and the width of the splicing line is less than the horizontal distances of continuous 5 picture elements which are in cross arrangement with the splicing line.

Description

technical field [0001] The invention relates to a three-dimensional printing system and a manufacturing method of the three-dimensional printing system. Background technique [0002] The projected image is easily distorted due to the aberration of the optical lens itself and the assembly tolerance of the system, so adjustment or correction is necessary to accurately control the projection size, so that when the projected image is used in 3D printing work, the accuracy of 3D printing can be achieved degree requirements. Furthermore, in 3D printing work, for example, in order to increase the print size, the projected images of more than two projectors need to be stitched together. However, the influence of optical lens aberration and system assembly tolerance easily makes image stitching difficult . The conventional stitching method is to first overlap the images and correct the distortion of the images, and then mix the overlapped images to make the brightness uniform, but ...
