Description

technical field [0001] The present invention relates to a 3D printing device and method, more specifically a rapid multi-material photocuring 3D printing device and method based on dual light sources. Background technique [0002] The light-curing 3D printing technology is limited by the performance of a single printing material, and it is difficult to give full play to its advantages such as high precision, high efficiency, and rapid prototyping of complex three-dimensional structures in practical applications. Therefore, in-depth research on multi-material photo-curing 3D printing technology is needed to expand its application range. At present, multi-material light-curing 3D printing technology includes multi-material multi-station printing and multi-material single-station printing, among which multi-material multi-station printing is in the absolute mainstream position, including multi-material pool station rotation switching and translation switching to realize Multip...
