Description
Technical Field
The invention relates to a path output method based on five-axis 3D printing software, and belongs to the field of application and design of 3D printing software.
Background
The Fused Deposition Modeling (FDM) -based 3D printing technology is one of the traditional printing technologies in the 3D printing field, and is popular with numerous device developers and users because the Fused Deposition Modeling (FDM) based 3D printing technology is simple in principle and easy to implement, and can be applied to printing various complex physical models and artware. However, the FDM printer in the market currently uses a 2.5-axis forming process, i.e., X-axis and Y-axis are linked, and the vertical axis Z is fed in stages. 5-axis 3D printing attracts the research of many experts and scholars at home and abroad as a higher-level printing technology. Although some colleges and universities have breakthrough progress in the field of five-axis 3D printing, the defect that an operator is required to perform one-time segmentation and generate a printing path continuously when a model is preprocessed exists all the time. Because the segmentation and generation must be performed once, the performance of the computer is highly required, and the operation process must be accurate. Therefore, the reasonable printing path output mode has important significance for improvement and popularization of the five-axis 3D printing technology.
Disclosure of Invention
The method aims to solve the problems that the existing five-axis 3D printing software is large in calculation task due to one-time segmentation when outputting a printing path. The invention provides a new printing path output mode, which mainly adopts the idea that only one section of a model is divided every time, and then a path for printing the section is output. When printing the next segment, it is only necessary to cut and output the path of the next segment next on the basis of the segment.
In order to achieve the purpose, the invention adopts the following technical scheme:
a path output method based on five-axis 3D printing software is characterized in that the five-axis 3D printing software only generates a division surface at a new position each time, a model is divided into a printing path part to be output and a part to be continuously divided, a printing path is output, and the steps are repeated aiming at the part to be continuously divided.
Further, the part between the dividing surface and the next dividing surface is the part of the printing path to be output.
Further, the position of the division plane is stored for each division, expressed by a coordinate point, and is displayed for the next division, and then the division plane is generated at the position.
Has the advantages that: 1. the existing five-axis 3D printing software is divided and generated at one time, has higher requirements on the performance of a computer, and requires that the operation process must be accurate. When a large complex model is processed, the defect is more prominent. The invention well makes up for the defect through the function of segmenting and outputting the model path and the operation of segmenting and cutting.
2. The invention designs the storage function of the model dividing surface. The key of the model division is to generate a division surface on the model, divide the model into several segments by the division surface, and then output a corresponding print path file. Based on the function of newly adding the position of the storage division surface, the position of the division surface is stored in software, when the next section of the model is to be divided, the position area of the stored division surface is displayed, a division surface is generated at the position, meanwhile, a division surface is newly generated at the other end of the section of the model, and the part of the model is cut out through the two division surfaces. The invention greatly improves the working efficiency, is flexible to operate, and reduces the requirements of 3D printing software on the performance of the computer in a segment-by-segment printing mode.

Detailed Description
The invention provides a novel path output method based on five-axis 3D printing software. Like other common 3D printing, the first step of realizing five-axis 3D printing is to preprocess a printing model through 3D printing software and output a printing path. When preprocessing a model, general five-axis 3D printing software requires an operator to perform one-time segmentation and continuously generate a printing path, as shown in fig. 1 (a). Because the segmentation and generation must be performed once, the performance of the computer is highly required, and the operation process must be accurate. When a large complex model is processed, the defect is more prominent. The invention well makes up for the defect through the function of segmenting and outputting the model path and the operation of segmenting and cutting. Only one segment of the model is segmented at a time and the path on which the segment is printed is output. When printing the next segment, it is only necessary to cut and generate the path of the next segment on the basis of the segment, as shown in fig. 1 (b).
Another innovation of the invention is that the storage function of the model splitting surface is designed. The key of the model division is to generate a division surface on the model, divide the model into several segments by the division surface, and then output a corresponding print path file. Based on the function of newly adding the position of the storage division surface, that is, storing the division surface in the software, displaying the position of the stored division surface when the next section of the model is to be divided, and simultaneously newly generating a division surface at the other end of the model section, and taking out the part of the model through the two division surfaces, as shown in fig. 1 (c). The invention greatly improves the working efficiency, is flexible to operate, and reduces the requirements of 3D printing software on the performance of the computer in a segment-by-segment printing mode.
Take the model shown in fig. 2 as an example.
The specific operation steps are as follows:
1. the segmentation plane is generated at a suitable position of the segmentation model, segmenting the first segment of the model, as shown in fig. 3 (a). The print path of the first stage is then output, as shown in fig. 3(b) and 3 (c).
2. After the printing path of the first section of the model is output, closing the software and then opening the software again, reading the model again, segmenting the second section of the model, and then outputting the printing path of the second section; in order to ensure that the printing starting point of the second segment is the printing end point of the first segment, namely, the consistency of the model in multi-segment printing is ensured, the position of the dividing surface 1 needs to be consistent with the position of the dividing surface in the previous step. It is common practice for the operator to remember the position of the segmentation plane in the previous step and then to create the same segmentation plane at the same position of the model when operating this step. Therefore, the present invention designs the storage function of the dividing plane, so that the operator only needs to store the position of the dividing plane when dividing the previous part, and reads the stored position of the dividing plane when the next part is divided, as shown in fig. 4 (a-1). A splitting plane is generated at this position as shown in fig. 4 (a-2). After the model is divided, only one dividing surface needs to be newly created at the other end of the model segment and the dividing surface is saved, as shown in fig. 4(b), thereby completing the division of the second segment. The print path of the second segment is then output, as shown in fig. 4(c) and 4 (d).
3. And closing the software, then opening the software again, reading the model again, and segmenting the third section of the model. The position of the last segmentation plane is first read, as shown in FIG. 5 (a-1). A splitting plane is generated at this position as shown in fig. 5 (a-2). After the model is divided, only another dividing surface needs to be created again at this time, and the dividing surface is saved, as shown in fig. 5(b), the third segment is divided. The print path of the third stage is then output as shown in fig. 5(c) and 5 (d).
The following provides a partial code embodiment of the present invention for saving the cut surface position, reading the cut surface position, and outputting in a file, and the embodiment is written in c + +, and the operating environment is openGL.
1. Preserving the position of the cut surface
2. Reading the position of the cutting surface
3. Model segment-by-segment output printing path
