Embodiment Construction
[0015] The invention provides a new path output method based on five-axis 3D printing software. Like other ordinary 3D printing, the first step to realize five-axis 3D printing is to preprocess the printing model through 3D printing software and output the printing path. When the general five-axis 3D printing software preprocesses the model, the operator is required to do one-time segmentation and continuously generate the printing path, as shown in Figure 1(a). Since it must be divided and generated at one time, there are high requirements for the performance of the computer, and the operation process must be accurate. This deficiency is even more pronounced when dealing with large and complex models. The present invention well makes up for this defect through the function of outputting the model path in segments and the operation of segment cutting. Only split a section of the model at a time, and then print the path of that section. When printing the next segment, you on...

The invention provides a path output method based on five-axis 3D printing software. According to the path output method, the five-axis 3D printing software only newly generates a segmentation plane every time, a model is divided into a printing path part to be output and a segmentation part to be continuously segmented, a printing path is output, and the steps are repeated for the segmentation part to be continuously segmented; the part between a segmentation surface and the next segmentation surface is the printing path part to be output; and the position of the segmentation surface is stored during each segmentation, and the position of the segmentation surface is displayed during the next segmentation. According to the path output method based on the five-axis 3D printing software, the defects of one-time segmentation and generation of existing five-axis 3D printing software are well overcome through the function of segmented output of the model path and the operation of segmented cutting; and the working efficiency is greatly improved, operation is flexible, and the requirement of the 3D printing software for computer performance is lowered in a section-by-section printing mode.
Description
technical field [0001] The invention relates to a path output method based on five-axis 3D printing software, which belongs to the field of application and design of 3D printing software. Background technique [0002] The 3D printing technology based on Fused Deposition Modeling (Fused Deposition Modeling, FDM) is one of the traditional printing technologies in the field of 3D printing. It is widely used by equipment developers because of its simple principle and easy implementation of printing materials in a molten state. And users are welcome, it can be applied to print various complex physical models and handicrafts. However, the FDM printers currently on the market use a 2.5-axis molding process, that is, the X-axis and Y-axis are linked, and the vertical axis Z is used for staged feed. As a higher-level printing technology, 5-axis 3D printing has attracted the research of many experts and scholars at home and abroad. Although some universities have made breakthroughs ...
