Problems solved by technology
Since the imaging component is fixed and projected from bottom to top, the imaging component is generally a light source plus DLP or liquid crystal. The quality of the light source determines the accuracy of the formed model. Generally, the brightness and resolution of the image formed by the imaging component are limited, and for most models, there is no Will reach the maximum size of the device, so for machines with fixed imaging components, most pixel utilization is low

Disclosed in the present invention is a stereoscopic photo-curing three-dimensional forming machine, comprising a rack provided with a movable platform assembly thereon. The end surface of the platform assembly is provided with an imaging assembly, and a forming container for containing liquid photosensitive resin is arranged above the imaging assembly. A bearing table is arranged in the forming container and is driven by a driving mechanism to vertically move in the forming container. The image rays emitted from the imaging assembly are irradiated to the bearing table through the bottom of the forming container, and the liquid photosensitive resin positioned between the bottom of the forming container and the bearing table is subjected to curing molding by image ray irradiation. According the present invention, the contradiction between the forming precision and the forming size of the traditional photo-curing molding machine can be solved, the imaging assembly can locally move by the movable platform assembly. In the same time, the complete section image on the same level is divided into multiple parts, the pixel of the imaging assembly is effectively utilized and the resolution ratio is improved by the sensitization curing of multiple parts, so as to improve the molding precision.
Description
technical field [0001] The invention relates to a stereolithography three-dimensional molding machine. Background technique [0002] Existing SLA (stereolithography) three-dimensional molding machines generally include an imaging assembly for generating cross-sectional images, a molding container filled with photosensitive resin, and a loading platform that can move up and down is provided in the molding container, and the imaging assembly is fixed. , the imaging component emits the light of the entire layer cross-sectional image through the bottom of the molding container, and projects it onto the carrier table in the molding container, one layer of solid is irradiated and solidified, and the entire solid shape is formed by layer-by-layer sequential superimposition. Since the imaging component is fixed and projected from bottom to top, the imaging component is generally a light source plus DLP or liquid crystal. The quality of the light source determines the accuracy of the...
