[0001] The present application relates to the field of metal additive manufacturing, and in particular to a 3D printing method, device, electronic device and storage medium. 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 returns to the initial position. 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 initial 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.

[0030] To facilitate understanding, some illustrations of concepts related to the embodiments of the present application are given by way of example for reference.

[0031] 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.

[0032] Please refer to Figure 1 , is a flow chart of the 3D printing method provided in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0033] Step 101: Obtain shape parameters of N print segments to be printed.

[0034] In some embodiments, the shape parameter is used to characterize the size of the printing segment, each printing segment corresponds to a shape parameter, the object to be printed includes a target slice layer to be printed, the target slice layer includes the N printing segments, and N is an integer greater than 1.

[0035] For example, the target slice layer includes 100 printing segments, which are numbered from printing segment 001 to printing segment 100. The 3D printing device starts from printing printing segment 001 and prints in sequence until it ends after printing printing segment 100.

[0036] Step 102: classify the N print segments according to the shape parameters, and match different scanning delays for the N print segments according to the classification results.

[0037] In some embodiments, the smaller the size of the print segment represented by the shape parameter is, the shorter the scanning delay matched by the print segment is.

[0038] How to match different scanning delays for N print segments according to the classification results is described in detail in the subsequent embodiments, and will not be described again here to avoid repetition.

[0039] Step 103: after the previous print segment is printed, the target print segment is printed after a delay according to the target scan matching the next target print segment.

[0040] In some embodiments, after the last print segment is printed, the target scan delay is waited for, and then the target print segment is printed.

[0041] In some embodiments, during the operation of the 3D printing device, the galvanometer motor controls the deflection of the lens, the laser light hits the galvanometer lens, and the galvanometer motor drives the lens to rotate, so that the laser sinters the specified pattern. Since the galvanometer motor needs to return to the initial position when printing the next print segment, after the previous print segment is completed (that is, after the galvanometer motor moves to the specified position corresponding to the previous print segment), the galvanometer motor needs a certain amount of time to return to the initial position of the galvanometer motor before it can receive the laser light again to start printing the next target print segment. In other words, for print segments with smaller shape parameters, the position distance of the galvanometer motor movement is shorter than the initial position, that is, the galvanometer motor only needs a shorter time to return to the initial position. Therefore, for target print segments with smaller shape parameters, matching a smaller target scanning delay can ensure that the galvanometer motor returns to the initial position within the target scanning delay, thereby ensuring the printing effect while improving the printing efficiency.

[0042] In addition, for printing segments with larger shape parameters, when the shape parameters are greater than a certain set value, the distance between the end position and the initial position of the galvanometer motor movement is a constant value. Therefore, a larger target scanning delay is set to ensure that the galvanometer motor returns to the initial position within the target scanning delay, thereby ensuring the printing effect.

[0043] For example, taking the shape parameter as the length of the print segment, the scanning delay corresponding to printing a 10 mm print segment and printing a 15 mm print segment is 100 microseconds, and the scanning delay corresponding to printing a 5 mm print segment is 70 microseconds.

[0044] Compared with the related art, the embodiment of the present application has at least the following advantages: by obtaining the shape parameters of each print segment, the size of each print segment is known, and then the N print segments are classified according to the shape parameters, so that each print segment matches a different scanning delay. Since the smaller the size of the print segment represented by the shape parameter, the shorter the scanning delay matched by the print segment, the waiting time of the laser can be saved, thereby improving the printing efficiency of the 3D printing device.

[0045] Please refer to Figure 2 , which is a flow chart of the 3D printing method provided in an embodiment of the present application. This embodiment is a specific description of the aforementioned embodiment, mainly illustrating: how to classify the print fragments, and how to match the scan delay for the print fragments according to the classification results.

[0046] The specific process of this embodiment is as follows Figure 2 As shown, the following steps are included:

[0047] Step 201: Obtain shape parameters of N print segments to be printed.

[0048] Step 202 : Compare the length of each printed segment with a preset length. If the length of the printed segment is less than or equal to the preset length, execute step 203 ; otherwise, execute step 205 .

[0049] In some embodiments, the size of the preset length can be set according to actual needs, and there is no specific limitation on the size of the preset length.

[0050] Step 203: Divide the print segment into short segments.

[0051] Step 204: Match the first scan delay for the short segment.

[0052] Step 205: Divide the print segment into long segments.

[0053] Step 206: Delay the second scan for matching the long segment.

[0054] In some embodiments, the second scanning delay is greater than the first scanning delay.

[0055] For example, assuming that the preset length is 10 mm, the first scanning delay is 50 microseconds, the second scanning delay is 100 microseconds, the printing segment 1 is 5 mm, the printing segment 2 is 8 mm, the printing segment 3 is 12 mm, and the printing segment 4 is 15 mm. Then the printing segments 1 and 2 are both short segments, and the printing segments 3 and 4 are both long segments. The printing segments 1 and 2 correspond to the first scanning delay, and the printing segments 3 and 4 correspond to the second scanning delay.

[0056] Step 207: after the last print segment is printed, delay printing of the target print segment according to the target scan matching the next target print segment.

[0057] Compared with the related art, the embodiment of the present application has at least the following advantages: by obtaining the shape parameters of each print segment, the size of each print segment is known, and then the N print segments are classified according to the shape parameters, so that each print segment matches a different scanning delay. Since the smaller the size of the print segment represented by the shape parameter, the shorter the scanning delay matched by the print segment, the waiting time of the laser can be saved, thereby improving the printing efficiency of the 3D printing device.

[0058] Please refer to Figure 3 , which is a flow chart of the 3D printing method provided in an embodiment of the present application. This embodiment is a specific description of the aforementioned embodiment, mainly illustrating: how to classify the print fragments, and how to match the scan delay for the print fragments according to the classification results.

[0059] The specific process of this embodiment is as follows Figure 3 As shown, the following steps are included:

[0060] Step 301: Obtain shape parameters of N print segments to be printed.

[0061] Step 302: inputting shape parameters into a shape recognition system of a 3D printing device so that the shape recognition system can classify the N printed segments.

[0062] Step 303: If the shape parameter is greater than or equal to the preset shape parameter, execute step 304; otherwise, execute step 305.

[0063] Step 304: Match a third scanning delay for the print segment corresponding to the shape parameter.

[0064] In some embodiments, taking the shape parameter as length as an example, if the length of the print segment is greater than or equal to a preset length, the print segment is matched with the third scanning delay.

[0065] In some embodiments, the size of the third scanning delay can be set according to actual needs, such as 100 microseconds, 120 microseconds, etc., and there is no specific limitation on the size of the third scanning delay.

[0066] Step 305: Determine a specific scanning delay according to the shape parameter, and match the specific scanning delay to the print segment corresponding to the shape parameter.

[0067] In some embodiments, taking the shape parameter as length, a correspondence formula between length and scanning delay can be set in the shape recognition system. After the length is sent to the shape recognition system, the shape recognition system calculates the specific scanning delay according to the above correspondence formula.

[0068] In some embodiments, taking the shape parameter as length as an example, different specific scanning delays corresponding to different length intervals can be set in the shape recognition system, such as setting the scanning delay corresponding to a print segment with a length greater than 0 and less than or equal to 3 mm to 40 microseconds, setting the scanning delay corresponding to a print segment with a length greater than 3 and less than or equal to 6 mm to 60 microseconds, setting the scanning delay corresponding to a print segment with a length greater than 6 and less than or equal to 8 mm to 70 microseconds, setting the scanning delay corresponding to a print segment with a length greater than 8 and less than or equal to 10 mm to 80 microseconds, and setting the scanning delay corresponding to a print segment with a length greater than 103 mm to 100 microseconds. After obtaining the shape parameter, it is detected which interval the length corresponding to the shape parameter belongs to, and the scanning delay corresponding to the interval is used as the specific scanning delay.

[0069] Step 306: After the previous print segment is printed, the target print segment is printed after a delay according to the target scan matching the next target print segment.

[0070] Compared with the related art, the embodiment of the present application has at least the following advantages: by obtaining the shape parameters of each print segment, the size of each print segment is known, and then the N print segments are classified according to the shape parameters, so that each print segment matches a different scanning delay. Since the smaller the size of the print segment represented by the shape parameter, the shorter the scanning delay matched by the print segment, the waiting time of the laser can be saved, thereby improving the printing efficiency of the 3D printing device.
