Title:
3D FORMING DEVICE AND METHOD EMPLOYING DMD SCAN IMAGING
Document Type and Number:
WIPO Patent Application WO/2019/148998
Kind Code:
A1
Abstract:
A 3D forming device and a method employing DMD scan imaging. The 3D forming device comprises an optical engine system (1), a displacement platform (2), and a synchronization control system (3). The optical engine system (1) is fixed on the displacement platform (2) to achieve displacement in an XY plane, and comprises a light source (11), a reflector (12), a DMD array (13), and a scanning lens (14). The displacement platform (2) and the optical engine system (1) are controlled by the synchronization control system (3) in a linked manner. The method comprises: the displacement platform (2) controlling the optical engine system (1) to move along X, Y and Z axes, the Z axis being a print height direction; performing graph slice layering processing in a graph height direction; performing, in the X direction according to an effective width d of the DMD, graph segmentation on a layered image, so as to obtain graph strips of a width d; scanning the segmented graph strip by strip in a DMD height direction. The method eliminates the defect that existing 3D printing technology based on DMD projection technology cannot perform both large-size printing and high-precision printing at the same time. The invention is advanced and practical and is suitable for widespread promotion and use.
