Description

Technical Field

[0001] The present invention belongs to the technical field of 3D printing control, and relates to a 3D printing control method and a control system. Background Art

[0002] 3D printing, a type of rapid prototyping technology, also known as additive manufacturing, is a technology that uses digital model files as the basis, using powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers, representing a new digital manufacturing method. With the development of technology, the application areas of 3D printing are also expanding. Therefore, the control of 3D printing is of great significance and importance.

[0003] Traditional management and control of 3D printing mainly involves creating or acquiring 3D models through modeling software, and then using slicing software to convert the 3D models into slicing files suitable for printing. At the same time, users manually set printing parameters in the slicing software to perform printing.

[0004] However, traditional 3D printing management and control lacks consideration of decomposing the parts of the object to be printed according to their different complexities, resulting in the use of the same printing parameters for printing parts of the same object with different complexities, thereby reducing the printing efficiency of the less complex parts and also reducing the accuracy, performance and reliability of the more complex parts, making it impossible to ensure that each part can achieve the expected accuracy and quality.

[0005] Traditional management and control of 3D printing ignores the fact that new users may not be able to accurately grasp the printing parameters of the objects to be printed, resulting in printing failures and wasted materials and time.

[0006] Traditional 3D printing control lacks monitoring and analysis of the printing effect of the object being printed, so it is impossible to understand whether the set printing parameters can ensure the printing effect of the object, nor can it guarantee the stability during the printing process. It is impossible to ensure that the printed object is highly consistent with the design model and meet the actual application needs. It is also impossible to avoid printing failures or product quality problems caused by parameter fluctuations. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figure 1 As shown, the present invention provides a control method for 3D printing, comprising the following steps: S1, 3D model construction: each object to be 3D printed is recorded as a designated object, and a model is constructed by a modeling software to obtain a 3D model corresponding to each designated object, and each decomposition part of the 3D model corresponding to each designated object is obtained according to a predefined principle, and basic information of each decomposition part of the 3D model corresponding to each designated object is obtained.

[0040] As a preferred feasible embodiment, the specific content of the predefined principle for obtaining the decomposition parts of the 3D model corresponding to each specified object is: dividing the 3D model corresponding to each specified object into the decomposition parts of the 3D model corresponding to each specified object according to the different detachable components, and recording them as the decomposition parts of the 3D model corresponding to each specified object.

[0041] As a preferred feasible embodiment, the basic information of each decomposed part of the 3D model corresponding to each designated object includes size, shape, structure and various detail elements.

[0042] It needs to be further explained that the specific method of obtaining the size, shape, structure and detail elements of each decomposed part of the 3D model corresponding to each designated object is: using modeling software to directly extract the size, shape, structure and detail elements of each decomposed part of the 3D model corresponding to each designated object from the constructed 3D model corresponding to each designated object.

[0043] As a specific example, the specified object is a Boeing 747 aircraft model, and the decomposed parts of the Boeing 747 aircraft model corresponding to the 3D model include but are not limited to wings, fuselage, tail, and landing gear.

[0044] The structure of the fuselage part of the Boeing 747 aircraft model corresponding to the 3D model is a common semi-monocoque structure.

[0045] The detailed elements of the fuselage part corresponding to the 3D model of the Boeing 747 aircraft model include but are not limited to the airline logo, the model of the aircraft and the detailed lines on the fuselage.

[0046] S2. Printing parameter matching: Analyze the complexity of each decomposed part of the 3D model corresponding to each designated object, so as to automatically match and obtain the printing parameters corresponding to each decomposed part of the 3D model corresponding to each designated object.

[0047] As a preferred feasible embodiment, the printing parameters corresponding to the decomposed parts of the 3D model corresponding to each designated object include layer height, filling density, shell thickness, interlayer adhesion and printing speed.

[0048] It should be further explained that the printing parameters corresponding to the decomposed parts of the 3D model corresponding to each designated object are printing parameters set in the slicing software after the decomposed parts of the 3D model corresponding to each designated object are sliced ​​and converted during the 3D printing process.

[0049] As a preferred feasible embodiment, the specific analysis process of the complexity of each decomposition part of the 3D model corresponding to each specified object is: extract the size, shape, structure and detail elements of each decomposition part of the 3D model corresponding to each specified object, and match them with the complexity index corresponding to each size, the complexity index corresponding to each shape, the complexity index corresponding to each structure and the complexity index corresponding to each detail element stored in the data storage library to obtain the complexity index corresponding to the size, the complexity index corresponding to the shape, the complexity index corresponding to the structure and the complexity index corresponding to the detail element of each decomposition part of the 3D model corresponding to each specified object.

[0050] It needs to be further explained that the complexity index is determined based on the manufacturing accuracy of the design scale, size, shape, structure and details of the 3D model corresponding to each specified object. It is a relative concept used to describe the complexity of the size, shape, structure and detail elements of each decomposed part of the 3D model corresponding to each specified object.

[0051] The complexity index corresponding to the structure and the complexity index corresponding to the detail element are not fixed values, but the complexity of each decomposed part of the 3D model corresponding to each specified object is analyzed. ,in Respectively The specified object corresponds to the 3D model The complexity index corresponding to the size of the decomposed parts, the complexity index corresponding to the shape, the complexity index corresponding to the structure and the complexity index corresponding to the The complexity index corresponding to the detail elements, They are the weight factors of the complexity corresponding to the complexity index corresponding to the set size, the complexity index corresponding to the shape, the complexity index corresponding to the structure, and the complexity index corresponding to the detail element. , is the number corresponding to each specified object, , is the number corresponding to each decomposition part, , The numbers corresponding to each detail element.

[0052] It needs to be further explained that the weight factors of the complexity corresponding to the complexity index corresponding to the set size, the complexity index corresponding to the shape, the complexity index corresponding to the structure and the complexity index corresponding to the detail element may be 0.2, 0.2, 0.2 and 0.4 respectively.

[0053] It needs to be further explained that size reflects the overall size of an object in three-dimensional space and is an important consideration in 3D printing, but it is usually not the only factor that determines the difficulty and complexity of printing. Therefore, a weight factor of 0.2 can reasonably reflect its impact.

[0054] Shape involves the geometry and contour of the object. Different shapes may require different printing strategies and techniques to handle. For example, some shapes may be more likely to lead to increased demand for support structures or reduced printing speeds. Therefore, a weight factor of 0.2 can reasonably reflect their impact.

[0055] The structure involves the layout, hierarchy, and connection relationships within the object. Complex structures may lead to stability issues during printing, uneven material distribution, and difficulties in post-processing. Therefore, a weight factor of 0.2 can reasonably reflect its impact.

[0056] Detail elements refer to small features, textures, and fine structures on the surface of an object. These detail elements often require high-precision printing technology and parameter settings to achieve, and they have a direct impact on the appearance and quality of the final product. Therefore, the complexity of detail elements accounts for a large proportion in the overall complexity assessment.

[0057] As a preferred feasible embodiment, the specific operation of automatically matching and obtaining the printing parameters corresponding to each decomposition part of the 3D model corresponding to each specified object is: matching the complexity of each decomposition part of the 3D model corresponding to each specified object with the printing parameters corresponding to each complexity stored in the information storage library, and obtaining the printing parameters corresponding to each decomposition part of the 3D model corresponding to each specified object, wherein the printing parameters include layer height, filling density, shell thickness, interlayer adhesion and printing speed, which are respectively recorded as .

[0061] It needs to be further explained that the physical samples of the decomposed parts of the 3D model corresponding to each designated object are specifically: the printed physical parts of the decomposed parts of the 3D model corresponding to each designated object within a set time period starting from the printing start time point are recorded as the physical samples of the decomposed parts of the 3D model corresponding to each designated object.

[0062] It needs to be further explained that the specific method of obtaining the displacement deviation of each monitoring point of the physical sample of each decomposition part of the 3D model corresponding to each designated object is: using laser scanning to scan the physical sample of each decomposition part of the 3D model corresponding to each designated object to obtain a three-dimensional data set, and using model building software to construct a three-dimensional model of the physical sample of each decomposition part of the 3D model corresponding to each designated object.

[0064] Then, according to the three-dimensional coordinate system of the 3D model corresponding to each designated object, the three-dimensional coordinates of each monitoring point of the physical sample of each decomposition part of the 3D model corresponding to each designated object are obtained in the three-dimensional model of the physical sample of each decomposition part of the 3D model corresponding to each designated object, which is recorded as ,in , is the number corresponding to each monitoring point, according to the calculation model Get the displacement deviation of each monitoring point of the physical sample of each decomposition part of the 3D model corresponding to each specified object , For the The specified object corresponds to the 3D model The first physical sample of the decomposition part The standard three-dimensional coordinates of the monitoring points.
