An incremental compression storage algorithm for slicing 3D model of DLP Printer

This paper presents a new binary image lossless compression algorithm for Digital Light Processing (DLP) printers. Considering the continuity of 3D model slicing images and the features of the pixels in slicing images, this algorithm is characterized by delta-encoding and two-stage compression to facilitate image compression, which is simple to implement. Compared with other algorithms used for image compression, the proposed one achieves the best performance when the same test cases are treated.
