摘要：

In order to solve the problem that the forming area of digital light processing (DLP) type 3D printer with surface exposure mode is limited and small, a technical scheme combining mobile splicing and dislocation equalization to eliminate seam marks is proposed. Firstly, the three-dimensional model is sliced evenly to form N-layer slices, then the slices are divided by a staggered method, which makes the splicing positions of adjacent layers staggered. Each slice is divided into M sliced bitmaps, which constitute the data source of 3D printing. Secondly, according to the parameters, the projector is moved along the X-axis to reach the corresponding exposure position. Each layer solidifies M bitmaps and splices them together to form a layer of slices. The splicing positions of slices are staggered layer by layer, and three-dimensional model entities are generated by superposition. The actual printing results show that the scheme can enlarge the forming size and improve the quality of the model with a small additional cost. © 2022 Science Press. All rights reserved.
