Problems solved by technology

[0002] The existing light-curing 3D molding machines based on DMD (Digital Micromirror Device) are all based on static graphic projection. The basic principle is projector technology, and the molding size is greatly limited in the pursuit of high precision. To achieve large-scale molding, it is necessary to expand the projected spot area, which will seriously affect the molding accuracy

Abstract

The invention provides a 3D (Three Dimensional) molding device and method of DMD (Digital Mirror Device) scanning imaging. The 3D molding device comprises an optical engine system, a displacement platform and a synchronous control system, wherein the optical engine system is fixed on the displacement platform to realize displacement in an XY plane and comprises a light source, a reflection mirror,a DMD array and a scanning lens; the displacement platform and the optical engine system are subjected to linked control by the synchronous control system. The method comprises the following steps: controlling the optical engine system to move along X, Y and Z axes through the displacement platform, wherein the Z axis is a printing height direction; carrying out graph slicing and layered treatment along a height direction of a graph; carrying out graph partitioning on the layered graph in the X direction according to the effective width d of DMD, so as to obtain each graph width d; scanning the partitioned graph in the height direction of the DMA one by one. According to the 3D molding device and method, provided by the invention, the defects that an existing 3D printing technology basedon a DMD projection technology cannot realize large-size and high-precision printing at the same time are overcome; the 3D molding device and method have relatively good technical characters and practicability and is suitable for being popularized and applied.
