[0002] The flange structure is a large tooling structure with flanges at both ends and a cavity connecting them in the middle. This structure is used in high-temperature environments, and the traditional manufacturing method is welding followed by machining. In recent years, due to the development of additive manufacturing technology, cooling water channels have been introduced into this structure to improve cooling efficiency, which has greatly enhanced the competitiveness of additively manufactured flanges. The flanges come in various shapes, including square, round, and polygonal.

[0058] To make the technical problems, technical solutions, and beneficial effects solved by the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0059] Reference Figure 1 The diagram illustrates a flowchart of a 3D printing method for flange parts according to an embodiment of the present invention, which may specifically include the following steps:

[0060] Step 101: Receive data of the first part component and generate the first part component;

[0061] In this embodiment of the invention, the method can be applied to a terminal, which may be a tablet computer, a personal computer, an all-in-one computer, etc. This embodiment of the invention does not limit the specific type of terminal. The operating system of the terminal may include Android, iOS, Windows Phone, Windows, etc. This invention does not impose too many restrictions on this.

[0062] The terminal can run the Magics3D printing application, and of course, it can also run other types of 3D printing applications. This embodiment of the invention does not impose too many restrictions on this.

[0063] Specifically, this method is mainly applied to flange parts or flange-like parts, such as parts with a large top volume and a small bottom volume, resembling a mushroom head. This embodiment of the invention does not impose too many restrictions on this.

[0064] The terminal can first receive data of the first part component and generate the first part component. For example, the terminal can receive the generation parameters of the first part component input by the user and generate the first part component in response to the generation parameters. Specifically, the first part component refers to a certain part of the part. In this embodiment of the invention, it may include the bottom outer ring part of the flange face. That is, the terminal can receive the generation parameters of the bottom outer ring part of the flange face input by the user and generate a three-dimensional image of the bottom outer ring of the flange face.

[0065] Step 102: Based on the first part, generate the first solid support;

[0066] After generating the first part, a first solid support can also be generated for the first part, that is, a first solid support can be generated on the bottom outer ring of the flange face. Specifically, the thickness of the solid support can be changed by setting the offset parameters to generate the first solid support. It should be noted that the first solid support refers to the solid support structure that needs to be added to the suspended area during the 3D printing process.

[0067] Step 103: After merging the first part component with the first solid support, a non-solid support is generated using the first solid support as the outer wall of the part.

[0068] In a further embodiment of the present invention, after obtaining the first part and the first solid support, the two can be merged first, and the first solid support can be used as the outer wall of the part, and a non-solid support can be generated on the outer wall of the part.

[0069] In a preferred embodiment, the non-solid support can be generated by setting scaling parameters. It should be noted that the non-solid support can refer to a non-solid support structure that needs to be added to the suspended area during the 3D printing process.

[0070] Step 104: Divide the first solid support into an upper solid support and a lower solid support, and merge the upper solid support with the first part to obtain the second part.

[0071] In practical applications of this invention, the first solid support can be divided into an upper solid support and a lower solid support. The upper solid support can be combined with the first part to obtain the second part, which can avoid the problem of poor flange flange caused by the solid support.

[0072] Step 105: Perform a hollowing operation on the lower solid support to obtain a hollowed-out lower solid support, and merge the hollowed-out lower solid support with the first solid support to obtain a second solid support;

[0073] For the lower solid support, it can be hollowed out to obtain a hollowed-out lower solid support, thereby reducing the printing volume and improving printing efficiency. Then, the hollowed-out lower solid support is merged with the first solid support to obtain the second solid support.

[0074] Step 106: Slice the second part component, the second solid support, and the non-solid support, and print the corresponding parts.

[0075] In this embodiment of the invention, the second part component, the second solid support, and the non-solid support are sliced ​​and 3D printed to obtain the corresponding part.

[0076] In this embodiment of the invention, the 3D printing method for flange parts includes: receiving data of a first part component and generating the first part component; generating a first solid support based on the first part component; merging the first part component and the first solid support, and generating a non-solid support with the first solid support as the outer wall of the part; dividing the first solid support to obtain an upper solid support and a lower solid support, and merging the upper solid support with the first part component to obtain a second part component; performing a hollowing operation on the lower solid support to obtain a hollowed-out lower solid support, and merging the hollowed-out lower solid support with the first solid support to obtain a second solid support; slicing the second part component, the second solid support, and the non-solid support to print the corresponding part. This method can reduce the difficulty of support design, reduce the amount of support used, improve printing efficiency, and produce parts with small deformation and high dimensional accuracy. By converting the support, the drawing difficulty is reduced, and the support is avoided from growing directly on the part or printing substrate, thereby reducing the support volume and improving printing efficiency.

[0077] In a preferred embodiment, refer to Figure 2 The flowchart illustrates a step for obtaining a second part component according to an embodiment of the present invention. The step involves dividing the first solid support to obtain an upper solid support and a lower solid support, and then merging the upper solid support with the first part component to obtain the second part component. The step includes:

[0078] Sub-step 11: Back up the first entity support to obtain the backed-up first entity support;

[0079] Sub-step 12 involves dividing the backup first physical support into an upper physical support and a lower physical support, and then merging the upper physical support with the first part component to obtain a second part component.

[0080] In this embodiment of the invention, after obtaining the first physical support, the first physical support can be backed up to ensure data security. Then, the backed-up first physical support is divided into an upper physical support and a lower physical support. The upper physical support is then merged with the first part component to obtain the second part component.

[0081] In one practical application embodiment, refer to Figure 3 The flowchart illustrates a first solid support generation step according to an embodiment of the present invention. The step of generating the first solid support based on a first part component includes:

[0082] Sub-step 21: Receive offset setting parameters for the first part component;

[0083] The terminal can receive offset setting parameters for the first part. The types of offset setting parameters may include XY axis offset, Z axis offset, and unsupported offset, etc. This embodiment of the invention does not impose too many restrictions on the types of offset setting parameters.

[0084] Sub-step 22: Based on the offset setting parameters of the first part component, generate the first solid support.

[0085] Based on the aforementioned offset setting parameters, the terminal generates the first solid support on the basis of the first part component.

[0086] In a preferred embodiment, refer to Figure 4 The flowchart illustrates a step for generating the non-physical support according to an embodiment of the present invention. The generation of the non-physical support includes:

[0087] Sub-step 31: Receive scaling setting parameters for the part component that merges the first part component with the first solid support;

[0088] Sub-step 32: Generate the non-physical support.

[0089] It should be noted that the scaling settings parameters may include X-axis offset parameters, Y-axis offset parameters, X-axis angle parameters, Y-axis angle parameters, center parameters, etc. of the scaling support projection area. This embodiment of the invention does not impose too many restrictions on the types of scaling settings parameters.

[0090] The terminal receives the scaling setting parameters for the merged part components, and in response to the scaling setting parameters, generates a non-solid support.

[0091] In a preferred embodiment, referring to Figure 5 , a flowchart of a splitting step of an embodiment of the present invention is shown. The splitting of the first solid support into an upper solid support and a lower solid support includes:

[0092] Sub-step 41: Receive the input parameters for the splitting size and control the splitting sizes of the upper solid support and the lower solid support;

[0093] Sub-step 42: Split the first solid support according to the splitting size to obtain an upper solid support with a height of 2 - 5 mm, and determine the remaining part of the first solid support as the lower solid support.

[0094] For the specific splitting steps, the terminal first receives the input parameters for the splitting size and controls the splitting sizes of the upper solid support and the lower solid support; splits the first solid support according to the splitting size to obtain an upper solid support with a height of 2 - 5 mm and the remaining lower solid support respectively, which can avoid the problem of poor flange flanging caused by the support.

[0095] [[ID=—]]In order to enable those skilled in the art to better understand the present invention, the following is illustrated by a specific example:

[0096] Step 1: The terminal first generates the outer ring part at the bottom of the upper flange in response to the input parameters, generates a solid support on the outer ring part at the bottom of the upper flange, changes the thickness of the solid support through offset parameters, and exports the solid support in stl format, such as Figure 6 .

[0097] Step 2: Import the solid support, back up the solid support and the part. Merge one of the parts and the solid support, and convert the solid support into the outer wall of the part. Then generate a non-solid support, and the non-solid support can grow on the outer wall of this part through scaling and other means, such as Figure 7 . This step greatly reduces the support volume and at the same time avoids part deformation caused by the support.

[0098] The support solution of the present invention consists of a solid support and a non-solid support. The solid support is obtained by setting parameters such as offset, and the non-solid support is obtained by setting parameters such as scaling.

[0099] Step 3: Export the solid support and the non-solid support. Name the solid support as support*_ex.stl and name the non-solid support as support*_ex1.stl.

[0100] It should be noted that there is a typo in the original text. "参照 Figure 5 ,示出了本发明实施例的一种分割步骤的流程图……" seems incomplete and unclear. I've translated it as best as possible based on the context. Also, I've corrected "为了使本领域技术人员更好了理解本发明" to "为了使本领域技术人员更好地理解本发明".Step 4: Divide the previously backed-up solid support into two parts, with the upper part being 2-5mm high. Then merge the upper part with the previously backed-up parts, as shown below. Figure 8 The merged parts can be saved as *.stl to avoid poor flange flanges caused by supports.

[0101] Step 5, cut out the lower part of the solid from the bottom to... Figure 7 The minimum support height in, such as Figure 9 This can reduce print volume and improve printing efficiency.

[0102] Step 6: Import the previous *_ex.stl file, which is the solid support file. Merge the hollowed-out lower part of the solid with it and save it as a new *_ex.stl file. Printing with solid support printing technology can improve printing efficiency.

[0103] Step 7: After importing the three required files *.stl, *_ex.stl, and *_ex1.stl, you can slice them and 3D print the corresponding parts.

[0104] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously.
