A printing path planning method, system and 3D printer

Abstract

The present invention relates to a printing path planning method, system and 3D printer. Firstly, the shape to be printed is divided into blocks through an optimized improved x-scanning method to obtain a plurality of preset rectangles corresponding to each angle, and then a plurality of preset rectangles corresponding to each angle are obtained. The method of scanning and based on the principle of optimal distance partitions the multiple preset rectangles corresponding to each angle, and finally, optimizes the preset rectangles for traversing each partition of each sub-domain corresponding to each angle according to the preset algorithm The path can not only ensure the printing accuracy, but also greatly reduce the length of the empty path of the shape to be printed in the two-dimensional layered slice image. Among them, the printing path corresponding to the lowest printing time is selected as the optimal printing path to further reduce Printing time, improve printing efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a printing path planning method, system and 3D printer. Background technique [0002] In recent years, rapid prototyping (RP), that is, 3D printing technology, as an additive manufacturing technology, has been widely used in various model production and product testing. Multiple two-dimensional layered slice images are then accumulated and printed layer by layer based on multiple two-dimensional layered slice images to form a solid model. Compared with subtractive manufacturing, it can process products with more complex structures. 3D printing technology has been differentiated after years of development. Many different manufacturing technologies have been developed. Among them, Stereolithography Apparatus (SLA), which uses the principle of photopolymerization of photosensitive resins, was the first to be researched and developed, and has become a relatively mature and widely...

Problems solved by technology

[0013] Although the global grid step-by-step traversal method can completely stitch the entire image, that is, the two-dimensional layered slice image, but because it does not analyze each image, that is, the two-dimensional layered slice image one by one, it is very likely to waste time Phenomena, for example, when the two-dimensional layered slice image is very small, but still need to traverse the entire working area, there is also the problem of empty travel similar to FDM technology, and the time wasted by the empty travel of each two-dimensional layered slice image is accumulated , will greatly increase the printing time of the entire part, and the printing efficiency is low
