Description

Technical Field

[0001] The present application relates to the field of metal additive manufacturing, and in particular to a delay parameter setting method for a 3D printing device and related equipment. Background Art

[0002] With the popularization of concepts such as intelligent manufacturing engineering and Industry 4.0, 3D printing technology is becoming more and more popular. 3D printing technology first appeared in the mid-1990s. It is actually the latest rapid prototyping device using technologies such as photocuring and paper lamination. It has basically the same working principle as ordinary printing. The printer is filled with "printing materials" such as liquid or powder. After connecting to the computer, the "printing materials" are stacked layer by layer through computer control, and finally the blueprint on the computer is turned into a physical object. This printing technology is called 3D stereoscopic printing technology.

[0003] In the related art, the laser of the 3D printing device will stop emitting light after each scan, and will start emitting light again after the galvanometer lens reaches the next target position and stabilizes. Therefore, the 3D printing device will set a delay parameter, and the laser needs to wait for a period of time corresponding to the delay parameter before emitting the laser to the galvanometer lens. In order to ensure that the galvanometer has reached the target position when the laser emits light, thereby ensuring the printing effect of the 3D printing device, the delay parameter will be set to a large value, resulting in a long waiting time, which in turn leads to low working efficiency of the 3D printing device. Summary of the invention

[0004] In view of this, the present application provides a delay parameter setting method for a 3D printing device and related equipment, which can improve the working efficiency of the 3D printing device while ensuring the printing effect.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0028] To facilitate understanding, some illustrations of concepts related to the embodiments of the present application are given by way of example for reference.

[0029] 3D printing equipment, also known as three-dimensional printers, is a rapid prototyping process equipment, usually using digital technology to print materials. 3D printing equipment is often used to manufacture models or parts in the fields of mold manufacturing, industrial design, etc.

[0030] Please refer to Figure 1 , which is a flow chart of a method for setting delay parameters of a 3D printing device provided in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0031] Step 101: After the slicing layer of the previous layer of the object to be printed is printed, the target slicing layer of the next layer of the object to be printed is printed according to the scanning delay parameter.

[0032] In some embodiments, the object to be printed includes N slice layers, and the 3D printing device prints the N slice layers in sequence according to a printing order, where N is an integer greater than 1.

[0033] For example, the object to be printed includes 100 slice layers, which are numbered from slice layer 001 to slice layer 100. The 3D printing device starts from printing slice layer 001 and prints in sequence until it ends after printing slice layer 100.

[0034] Specifically, after the previous slice layer is printed, wait for a preset time according to the scanning delay parameter and then print the target slice layer.

[0035] In some embodiments, the object to be printed has a slicing file, which includes a scanning speed and a scanning power corresponding to each of the N slicing layers. By reading the slicing file of the object to be printed, on the one hand, the scanning speed and the scanning rate corresponding to the target slicing layer can be known, so that the 3D printing device prints the target slicing layer according to the scanning speed and the scanning rate corresponding to the target slicing layer; on the other hand, the scanning delay parameter can be determined according to the scanning speed and the scanning power corresponding to the target slicing layer, thereby saving the time for subsequent adjustment of the scanning delay parameter.

[0036] Step 102: After the target slice layer is printed, a first defect identification is performed on the target slice layer.

[0037] In some embodiments, the 3D printing device includes a defect recognition system, and the defect recognition system performs a first defect recognition on the target slice layer.

[0038] Specifically, a target image of a target slice layer is captured by a capturing device of the 3D printing device, and the defect recognition system compares the target image with a template image corresponding to the target slice layer to recognize whether there is a defect in the target slice layer.

[0039] More specifically, the defect recognition system performs binarization processing on both the target image and the template image corresponding to the target slice layer; and compares whether the difference between the target image after binarization processing and the template image after binarization processing meets the preset requirements. For example, by comparing the target image after binarization processing and the template image after binarization processing, it is detected whether there are abnormal spots or poorly spliced ​​parts in the target image. If the defect recognition system recognizes that there are abnormal spots or poorly spliced ​​parts in the target image, it means that the difference between the target image after binarization processing and the template image after binarization processing does not meet the preset requirements.

[0040] It can be understood that the template image corresponding to the target slice layer is a standard image of the target slice layer without defects.

[0041] Step 103: When the result of the first defect identification is that a defect exists in the target slice layer, adjust the scanning delay parameter.

[0042] In some embodiments, if the result of the first defect identification is that there is a defect in the target slice layer, that is, the difference between the target image after binarization processing and the template image after binarization processing does not meet the preset requirements, the scanning delay parameter is increased.

[0043] Specifically, during the operation of the 3D printing device, the galvanometer motor controls the deflection of the lens, and the laser light hits the galvanometer lens, which is driven by the galvanometer motor to rotate, so that the laser sinters the specified pattern. Due to the inertia of the galvanometer motor, after the galvanometer motor moves to the specified position, the lens needs a certain amount of time to stabilize before it can receive the laser light, otherwise abnormal light spots will appear in the slice layer. In other words, when the scanning delay parameter is set too small and the lens is not in a stable state, it will cause abnormal light spots or poorly spliced ​​parts in the printed target slice layer. At this time, the scanning delay parameter needs to be adjusted appropriately to ensure that the lens is in a stable state after the galvanometer motor moves to the specified position and passes through the scanning delay parameter.

[0044] Step 104: Print the target slice layer again according to the adjusted scanning delay parameters.

[0045] Step 105: Perform the first defect identification on the target slice layer again. If the result of the first defect identification is that there is no defect in the target slice layer, the process ends; otherwise, execute step 103.

[0046] In some embodiments, the initial scanning delay parameter is set to be relatively small, and then the final scanning delay parameter is adjusted continuously to be the optimal and shortest scanning delay parameter for printing the target slice layer.

[0047] Compared with the related art, the embodiments of the present application have at least the following advantages: by performing the first defect recognition on the target slice layer, it is easy to detect whether the printed target slice layer has defects, such as abnormal light spots or poorly spliced ​​parts, and adjusting the scanning delay parameters when the target slice layer is detected to have defects, so as to improve the printing effect of the target printed layer. By reprinting the target slice layer according to the adjusted target scanning delay parameters, and performing the first defect recognition on the reprinted target slice layer again, and adjusting the scanning delay parameters again when the target slice layer is detected to have defects, the above process is repeated until the printed shape of the target slice layer meets the preset printing requirements. On the one hand, the target scanning delay parameters can be shortened as much as possible, thereby improving the working efficiency of the 3D printing device; on the other hand, the printing effect of the 3D printing device can be ensured, and the stability of the 3D printing device can be improved.

[0048] Please refer to Figure 2 , which is a flow chart of a delay parameter setting method for a 3D printing device provided in an embodiment of the present application. This embodiment is a further improvement on the aforementioned embodiment. The main improvement is that: in this embodiment, the delay parameters will be adjusted again during the formal printing process to further improve the working efficiency of the 3D printing device.

[0049] The specific process of this embodiment is as follows Figure 2 As shown, the following steps are included:

[0050] Step 201: Perform debugging printing on the object to be printed.

[0051] Step 202: During the debugging printing process, after the previous slice layer is printed, the next target slice layer is printed according to the scanning delay parameter.

[0052] Step 203: After the target slice layer is printed, a first defect identification is performed on the target slice layer.

[0053] Step 204: When the result of the first defect identification is that a defect exists in the target slice layer, adjust the scanning delay parameter.

[0054] Step 205: Print the target slice layer again according to the adjusted scanning delay parameters.

[0055] Step 206: Perform the first defect identification on the target slice layer again. If the result of the first defect identification is that the target slice layer has no defects, execute step 207; otherwise, execute step 204.

[0056] Steps 201 to 206 of this embodiment are similar to steps 101 to 105 of the above-mentioned embodiment, and will not be described again to avoid repetition.

[0057] Step 207: formally printing the object to be printed. During the formal printing process, after the printing of the previous formal slice layer is completed, the next formal target slice layer is printed according to the final scanning delay parameter.

[0058] In some embodiments, the final scanning delay parameter is the scanning delay parameter that is finally adjusted during the debugging printing process.

[0059] Step 208: Perform a second defect identification on the formal target slice layer, and adjust the final scanning delay parameter again when the result of the second defect identification is that the formal target slice layer has defects.

[0060] In some embodiments, before performing a second defect identification on the formal target slice layer, it also includes: detecting whether the formal target slice layer is the first M layers among the N slice layers, where M is an integer greater than 1 and less than N; performing a second defect identification on the formal target slice layer includes: when detecting that the formal target slice layer is the first M layers among the N slice layers, performing a second defect identification on the formal target slice layer.

[0061] Specifically, in the formal printing process, the first M slicing layers are usually the supporting parts of the object to be printed, and the supporting parts do not require the optimal printing effect. Therefore, even if defects are detected in the formal target slicing layers printed according to the final scanning delay parameters, the final scanning delay parameters can be fine-tuned in time, thereby ensuring that the subsequent main body printing effect of the object to be printed is excellent.

[0062] For example, the object to be printed includes 100 slice layers, and the first 10 layers are all supporting parts of the object to be printed. In the process of printing the first 10 layers, the second defect recognition can be performed on the formal target slice layer to adjust the final scanning delay parameters.

[0063] Compared with the related art, the embodiments of the present application have at least the following advantages: by performing the first defect recognition on the target slice layer, it is easy to detect whether the printed target slice layer has defects, such as abnormal light spots or poorly spliced ​​parts, and adjusting the scanning delay parameters when the target slice layer is detected to have defects, so as to improve the printing effect of the target printed layer. By reprinting the target slice layer according to the adjusted target scanning delay parameters, and performing the first defect recognition on the reprinted target slice layer again, and adjusting the scanning delay parameters again when the target slice layer is detected to have defects, the above process is repeated until the printed shape of the target slice layer meets the preset printing requirements. On the one hand, the target scanning delay parameters can be shortened as much as possible, thereby improving the working efficiency of the 3D printing device; on the other hand, the printing effect of the 3D printing device can be ensured, and the stability of the 3D printing device can be improved.

[0064] Please refer to Figure 3 , which is a functional module diagram of a delay parameter setting device 300 for a 3D printing device provided in an embodiment of the present application.

[0065] like Figure 3 As shown, the delay parameter setting device 300 of the 3D printing device includes: a printing module 302 and a defect recognition module 303; the printing module 302 is used to print the target slice layer of the next layer of the object to be printed according to the scanning delay parameter after the slice layer of the previous layer of the object to be printed is printed; wherein the object to be printed includes N slice layers, and the 3D printing device prints the N slice layers in sequence according to the printing order; the defect recognition module 303 is used to perform a first defect recognition on the target slice layer after the target slice layer is printed, and adjust the scanning delay parameter when the result of the first defect recognition is that the target slice layer has a defect; the printing module 302 is also used to print the target slice layer again according to the adjusted scanning delay parameter, and the defect recognition module 303 is also used to repeat the first defect recognition on the target slice layer and adjust the adjusted scanning delay parameter again until the result of the first defect recognition is that the target slice layer has no defect.

[0066] In some embodiments, the delay parameter setting device 300 of the 3D printing device also includes a reading module 301, which is used to read a slicing file of the object to be printed, and the slicing file includes a scanning speed and a scanning power corresponding to each of the N slicing layers; the reading module 301 is also used to determine the scanning delay parameter according to the scanning speed and scanning power corresponding to the target slicing layer.

[0067] Compared with the related art, the embodiments of the present application have at least the following advantages: by performing the first defect recognition on the target slice layer, it is easy to detect whether the printed target slice layer has defects, such as abnormal light spots or poorly spliced ​​parts, and adjusting the scanning delay parameters when the target slice layer is detected to have defects, so as to improve the printing effect of the target printed layer. By reprinting the target slice layer according to the adjusted target scanning delay parameters, and performing the first defect recognition on the reprinted target slice layer again, and adjusting the scanning delay parameters again when the target slice layer is detected to have defects, the above process is repeated until the printed shape of the target slice layer meets the preset printing requirements. On the one hand, the target scanning delay parameters can be shortened as much as possible, thereby improving the working efficiency of the 3D printing device; on the other hand, the printing effect of the 3D printing device can be ensured, and the stability of the 3D printing device can be improved.
