[0001] This invention relates to the field of 3D printing, and more specifically, to a testing method, apparatus, storage medium, and electronic device for 3D printing equipment. Background Technology

[0002] The production process of 3D printer equipment is cumbersome. Production testing and verification account for 50% of the printer production time. Verification methods are cumbersome and complex, and it is easy to miss or fail to detect certain items. Testing and statistics all depend on individual operation, which is time-consuming and cannot be traced back to each process. If you want to find the equipment's production records, you need to search local data, which is incomplete.

[0003] Currently, there are no good means of measuring whether a 3D printer is stable, meets design requirements, and whether its embedded algorithms execute correctly as designed. The only way is to check the test results by actually printing a model. However, the statistical methods used in the process are unclear and ambiguous, and further evaluation requires human experience.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] According to a first aspect of the present invention, a testing method for a 3D printing device is provided, optionally, as follows: Figure 1 As shown, the above method includes:

[0038] S102, Generate a test set file based on the test items of the 3D printing equipment to be tested; wherein, the test set file is used to instruct the 3D printing equipment to perform the corresponding 3D printing actions;

[0039] The test set file may include slice files and / or other control instructions. A slice file is a data file obtained by slicing the model to be printed. It may include printing configuration data, material and process configuration data, printer adaptation configuration data, cross-sectional data, etc. The 3D printing equipment can perform corresponding printing actions based on this slice file, such as exposure power and exposure images. The target slice file is a slice file generated according to the specific test item.

[0040] The tests cover various aspects, such as testing the effectiveness of print projection edge accuracy, the effectiveness of print residue optimization, print projection rule verification, and the effectiveness of scraping enhancement. Specifically, for the intelligent printing test objectives, a common hardware architecture is used: a camera compatible with the printer platform's mounting structure is mounted above the printing platform, forming a 90-degree perpendicular parallel with the optical engine. A common pre-test method is employed: capturing a 90° projection image directly above the optical engine, and then analyzing various image metrics for testing different intelligent printing tasks. This detection method effectively reduces the workload of manually visually judging the print projection image. For the test objective of testing print projection edge accuracy, a key metric is selected: image pixel cluster fitting similarity. A testing method involves layer-by-layer detection of the image's edge fitting similarity; results within the acceptable similarity range indicate a passed edge accuracy test. Similarly, for the test objective of testing print residue optimization, a key metric is selected: the number of closed connected group images in the image. A testing method involves layer-by-layer detection of the number of closed connected group images in the image; results within the acceptable group number range indicate a passed image residue optimization test. For the test objective: the effectiveness of shovel enhancement, the selected test metric is the width of the graphical connected group. The test method involves subtracting layers at intervals to obtain the width of the graphical connected group. Widths within the acceptable range are considered successful for image artifact optimization. For the test objective: verification of print projection rules, the selected test metric is the image sequence number. The test method involves inputting print layer rules and comparing the sequence number with the rule layer by layer. Projection rules with a matching score within the specified range are considered valid.

[0041] S104, acquire test data during the 3D printing process of the 3D printing equipment performing the corresponding 3D printing action;

[0042] S106. Based on the test data, determine the test results of the 3D printing equipment.

[0043] The testing methods described above for 3D printing equipment can be applied during the testing process. The 3D printing equipment performs test prints or real-world prints, and the test results are determined by acquiring the test data generated during the printing process. The 3D printing action described above is an image projection action.

[0044] The test data mentioned above can be used to analyze the 3D printing equipment during the preparation, printing, post-printing recovery, and adjustment processes, based on the target slice file. This test data allows us to check whether the printing process and results meet the requirements.

[0045] Test results can be used to characterize whether a 3D printing device is qualified or unqualified, or to characterize which part of the 3D printing device has a problem, or to characterize the accuracy of the 3D printing device.

[0046] In the above method, for 3D printing equipment, a test set file can be generated according to the item to be tested, and the 3D printing equipment can be instructed to print according to the test set file to obtain test data. Based on the test data, the test results of the 3D printing equipment can be determined, thereby achieving the goal of improving the testing efficiency of 3D printing equipment and solving the technical problem of low testing efficiency of 3D printers.

[0047] As an optional example, the test set file includes a target slice file. Determining the target slice file based on the test item of the 3D printing device to be tested includes: obtaining a standard slice file; and adjusting the standard slice file according to the test item to obtain the target slice file.

[0048] Optionally, once the test item is determined, a target slice file can be generated and sent to the 3D printer for printing. The target slice file can be generated based on a standard slice file. The standard slice file can be a slice file containing basic printing information, and can be obtained by adding, deleting, querying, and modifying standard slice files. The standard slice file can be pre-set. Different types of test items can use different standard slice files. The target slice file is obtained by adjusting the standard slice file. This step can improve the efficiency of generating the target slice file.

[0049] As an optional example, adjusting the standard slice file according to the project to be tested includes: if slice data corresponding to the project to be tested exists in the standard slice file, the standard slice file is determined as the target slice file; if slice data corresponding to the project to be tested does not exist in the standard slice file, the standard slice file is adjusted according to the project to be tested to obtain the target slice file.

[0050] Optionally, in this embodiment, since the items to be tested may be diverse, the standard slice file may not contain the slice data required by the items to be tested. When generating the target slice file using the standard test file, it is first checked whether the standard test file contains slice data corresponding to the items to be tested. If the slice data exists in the standard slice file, the standard slice file is used as the target slice file. If the standard slice file contains data other than the slice data, the extra data can be deleted or retained. If the standard slice file does not contain slice data, test data can be generated according to the items to be tested, and then the test data can be added to the standard slice file to obtain the target slice file.

[0051] As an optional example, adjusting the standard slice file according to the project to be tested includes: obtaining a plaintext view of the standard slice file, wherein the plaintext view includes an initial entity cross-section view; determining a target entity cross-section view of the plaintext view according to the project to be tested; and replacing the initial entity cross-section view with the target entity cross-section view to obtain the target slice file.

[0052] Optionally, this embodiment posits that the standard slice file does not contain slice data. In this case, the standard slice file can be adjusted according to the project to be tested to obtain the target slice file.

[0053] When adjusting a standard slice file, a plaintext view of the standard slice file can be obtained. A plaintext view is a view that can be visually observed. For example, an image, multiple pixels, etc., can be recognized by the human eye or machine vision. The plaintext view can contain the initial solid cross-sectional view of the slices in the slice file. The initial solid interface view can contain a slice of the item to be printed, which includes both item and non-item portions.

[0054] The target entity interface diagram is the graphic of the slice determined based on the item to be tested, that is, the graphic that the item to be tested will be printed in this slice.

[0055] As an optional example, determining the target entity cross-section of the plaintext view based on the test item includes: determining the position and number of each initial entity cross-section in the plaintext view based on the test item; determining the range of each initial entity cross-section according to its position, and calculating the plaintext pixel region and the number of connected components of each initial entity cross-section based on its range; removing interfering pixels from each initial entity cross-section based on the plaintext pixel region and the number of connected components; reducing the initial entity cross-section after removing interfering pixels according to the number of pixels, and determining the reduced initial entity cross-section as the target entity cross-section.

[0056] Optionally, in this embodiment, after determining the initial cross-sectional view of the plaintext view of the item to be tested, the initial cross-sectional view can be adjusted. The position of the initial cross-sectional view mentioned above is the position of the content of the object corresponding to the item to be printed in the image in the initial interface view. For example, the number of initial cross-sectional views mentioned above can be the number of initial cross-sectional views, that is, the number of layers to be printed.

[0057] As an optional example, determining the test results of a 3D printing device based on test data includes: comparing the test data with theoretical parameters, where the theoretical parameters are the operating parameters of the 3D printing device under normal conditions; if the test data matches the theoretical parameters, the 3D printing device is determined to be normal; if the test data does not match the theoretical parameters, the 3D printing device is determined to be abnormal.

[0058] Optionally, in this embodiment, after the 3D printing device performs the printing action according to the target slice file and obtains the test data, the test data can be compared with the theoretical test to determine whether the test data is normal.

[0059] The theoretical data mentioned above can be obtained by printing using a 3D printing device that has been tested manually and is functioning normally, following the same printing process. This data represents theoretical parameters.

[0060] When comparing test data with operating parameters, one method is to check if they match, such as whether they are identical or if the difference is within the allowable fluctuation range. Another method is to compare the magnitude of the difference; a large difference indicates abnormal test data, while a small difference indicates normal test data. The magnitude of the difference can be constrained by a predetermined value; exceeding the predetermined value is considered too large.

[0061] As an optional example, before determining the target slice file based on the test item of the 3D printing device to be tested, the above method also includes: configuring a test environment for the 3D printing device to print the target slice file.

[0062] As an optional example, configuring a test environment for printing target slice files for a 3D printing device includes: obtaining the printing device parameters of the 3D printing device; and sending a script file containing the printing device parameters to the 3D printing device so that the 3D printing device can run the script file.

[0063] Optionally, in this embodiment, the 3D printing device needs to be configured with a test environment for printing test set files before testing.

[0064] The test environment can be configured by setting the parameters and data required for the 3D printing equipment, which can be done via a script file. The script file is then sent to the 3D printing equipment, which runs the script file to operate the test environment. After running the script file, the 3D printing equipment is then tested within this test environment.

[0065] As an optional example, the following steps are also included:

[0066] Upon receiving the current test data obtained by the 3D printing device from printing the current test set file, the system determines, based on the current test data, whether to print the next test set file or to stop testing the 3D printing device.

[0067] Optionally, in this embodiment, the testing of the 3D printing equipment can be divided into multiple stages. Each test set file can be printed by the 3D printing equipment. After printing, the current test data during the printing process can be collected, and the normality of the current test data can be checked. If the current test data is normal, the printing and testing of the next test set file can continue. If the current test data is abnormal, the test can be stopped or paused.

[0068] As an alternative example, after determining the target slice file based on the test item of the 3D printing device to be tested, the above method further includes: sending the target slice file to middleware so that the middleware sends the target slice file to the 3D printing device.

[0069] In this embodiment, middleware can be used as a relay device for the 3D printing equipment. The middleware transmits target slices to the 3D printing equipment, allowing the 3D printing equipment to communicate with other devices.

[0070] As an optional example, before or after the 3D printing device performs the 3D printing action according to the target slice file, the above method also includes: determining a test task; and using the test task to perform an internet test on the 3D printing device.

[0071] As an optional example, the test task is at least one of the following: issuing a print job, deleting a print job, upgrading a software / process package, or enabling / disabling a software / process package.

[0072] In this embodiment, in addition to printing tests on the 3D printing equipment, internet tests can also be performed on the 3D printing equipment. Internet testing is used to test the network connectivity of the 3D printing equipment. Internet testing can be performed by at least one of the following: issuing print jobs, deleting print jobs, upgrading software / process packages, and enabling / disabling software / process packages.

[0073] As an optional example, performing Internet testing on a 3D printing device using a test task includes: sending a notification message to the 3D printing device via the Internet of Things (IoT) to enable the 3D printing device to perform a test task; receiving the processing results of the 3D printing device performing the test task via the IoT; and performing a full verification of the processing results.

[0074] In this embodiment, after the 3D printing equipment executes the test task, a full verification of the test task processing results can be performed. The results of the full verification are used to check whether the internet test passed.

[0075] Figure 2This is a system flowchart for this embodiment. In this embodiment, a 3D printer is used as an example of a 3D printing device. The cloud is responsible for data processing and can be used for automated production line inspection and traceability of the 3D printer, and can verify the barcode information of the 3D printer. The cloud can communicate with a computer terminal (PC). The computer terminal contains a testing program.

[0076] During testing, first import the 3D printer's unique code, and then start the PC terminal testing program to automatically execute the test.

[0077] The PC automatically sends test items to different devices and then to the device middleware. The device middleware enables compatibility of 3D printers across different software and hardware platforms. The middleware interacts with the 3D printer, executes tests according to protocol instructions, and returns results. The PC collects data and uploads it to the test cloud for data analysis and evaluation.

[0078] By inputting the 3D printer's device code, the cloud center can trace the production testing process and view production data, thereby achieving data traceability.

[0079] Figure 3 This is a schematic diagram of automatic calibration and data acquisition feedback in this embodiment.

[0080] The test is initiated from the PC program, which remotely connects to the device middleware via the device IP and uploads the test slice file to the test printer.

[0081] The device middleware executes the slice file according to the issued instructions. The PC program collects test data through sensors such as light sensors, ultraviolet light sensors, displacement sensors, and cameras and feeds it back to the cloud. The cloud processes the data and feeds it back to the printer for data calibration.

[0082] By combining the design of the slicing with the sensors, targeted testing of each functional module of the printer can be achieved, and the test results can be judged and synchronized to the cloud center for data processing and statistics.

[0083] Figure 4 This is a schematic diagram of the test slice design in this embodiment.

[0084] 3D printer automatic monitoring, calibration, stability and modular testing: Test the functionality of each module of the printer by designing test slice files.

[0085] Figure 5 This is a schematic diagram of another slice design in this embodiment.

[0086] Figure 6 This is a flowchart of the automatic testing process in this embodiment.

[0087] The business logic testing module (API) sends instructions to the printer, including issuing / deleting print jobs, software upgrades, process package upgrades, enabling / disabling process packages, and downloading logs.

[0088] After receiving these instructions, the printer will report the corresponding status information to the platform. The data verification module will verify this status information and output the verification results in real time.

[0089] The UI automation module controls the printer to select print jobs via virtual mouse, touchscreen, and other touch-screen modules. During printing, the printer reports printing status information in real time, and the data verification module verifies this information and outputs any verification errors in real time.

[0090] 3D Printer Automated Test Management:

[0091] The platform enables the configuration and management of test scripts and online review of test reports. To improve product testing methods and quality, it provides online control over the configuration of the testing environment, test scripts, test cases, and the platform for test execution. This allows ordinary testers or other production line testers to independently conduct tests and quickly automate the testing of 3D printers. Even if requirements change, the platform can be quickly updated and deployed through simple configuration changes, thereby improving testing efficiency.

[0092] Let's illustrate this with an example.

[0093] In this embodiment, on the PC, the user can select different functions of the system according to their needs. If the automated testing of the 3D printer is selected, the user can enter the 3D printer automated production testing and traceability system. Then, automatic calibration and monitoring of the 3D printer can be performed. If testing of the 3D printer is required, either 3D printer module function and performance testing or 3D printer network (Internet of Things, IoT) function testing can be performed. The unique code of the device can be entered by scanning a code, and the test can begin according to the preset printer type. The PC program connects to the device middleware via TCP. The middleware connects to the printer using serial port, TCP, and other methods, and begins issuing test items according to the preset process. After receiving the instructions, the 3D printer begins executing the test and returns the test results to the device middleware. Based on the result of the current test item, the system determines whether to proceed to the next test item or end the test. The middleware returns data to the PC program, which processes the data and feeds the test results back to the cloud. The cloud parses the collected data, saves it, and outputs the final conclusion to the PC program, informing it of the test results. All data is stored and a query interface is provided. All test results can be traced through the unique device code.

[0094] During the test, the PC program can connect to the device printer and set theoretical test data values, such as testing the printer's light intensity, setting parameters such as ambient light intensity, expected projection value, design time, and strategy duration.

[0095] (1) Import the designed slice file;

[0096] (2) Start printing and use sensors to record actual values. Perform algorithm filtering on the data returned by the sensors and record the time, the current number of slices to be printed, the current function and the function algorithm.

[0097] (3) Repeat the above steps until the sliced ​​file is printed;

[0098] (4) The data is returned to the PC program. The PC program parses and packages the data and sends it back to the cloud server for processing. After the cloud server parses the data, it sends the data back to the printer and the PC for data correction of printing parameters and judgment parameters.

[0099] The main process for designing sliced ​​files is as follows:

[0100] Open the slice, decrypt it to obtain a plaintext view, and view the existing information in the slice file.

[0101] Make judgments based on the test requirements. If it is necessary to change the printing configuration, reset the material name, material precision and other information according to the test points.

[0102] Update the 2D cross-sectional image. Calculate the projection sensor positions and number according to the test plan. Based on the photometer and illuminometer's light-sensing range and shape, calculate the white pixel area and connected pixels of the 2D graphic. Remove interference from gray transition pixels to reconstruct a new solid cross-sectional image. Select and discard support, contour, and base plate cross-sectional images according to test requirements. Update the layer retrieval file and the number of unit layers according to the number of tests. Use a multi-process loop to reduce image generation time. Save the file and exit editing.

[0103] By designing different slice files, it is possible to perform individual tests on a specific module or function of the printer. By configuring printer parameters, single-function configurations can be achieved, such as single spindle movement, single DLP printer light projection, and independent movement of the liquid dispensing module, thereby realizing automated testing of the module's function and performance.

[0104] Meanwhile, the sliced ​​files can also be designed with a separate algorithm for the printer or a fusion of multiple algorithms for data verification to check whether the algorithm's processing results are consistent with the preset and how much the deviation range is.

[0105] For IoT testing of 3D printers, such as Figure 7As shown, the business logic module mainly implements business interactions with the printer, including issuing / deleting print jobs, upgrading software / process packages, and enabling / disabling process packages. The data validation module mainly performs full validation of the data returned by the printer, including field names, field types, and field values. The following example illustrates this:

[0106] (1) The business logic module sends task instructions to the printer;

[0107] (2) After receiving the instruction, the printer downloads the task and replies with the download result after the download is completed;

[0108] (3) The data verification module verifies the download result information;

[0109] (4) Finally, display the verification results on the test platform.

[0110] See attached document Figure 8 This is a flowchart of the printer IoT automatic printing task in this solution. The UI module mainly controls the printer through click operations, while the data validation module performs full validation of the data returned by the printer, including field names, field types, and field values. Details are as follows:

[0111] (1) Control the printer to select the task and start printing through the UI module;

[0112] (2) The printer reports the status information during printing, and the data verification module verifies the information;

[0113] (3) The printer reports sensor status information, and the data verification module verifies it;

[0114] (4) After printing is complete, the data verification module will display the results on the test platform.

[0115] Figure 9 This is the overall framework diagram of the cloud-based functions in this solution, realizing the process from product requirements to unattended execution, improving the flexibility of testing process access, unified resource configuration, and intelligence. The page mainly controls the input and output of test cases, printer configuration, and automatic execution functions, as detailed below:

[0116] Enter the printer model, serial number, and system type on the page, and save it to the database.

[0117] Based on the entered data, the required configuration parameters are written online. After editing, the backend interface is called to send the configuration script to the printer and execute it. After execution, the results are sent back to the front end to display the device's environment configuration status, aiming to achieve the environment required for the test cases of this model.

[0118] After the environment is configured, test cases are written based on the SN. UI and API tests are optional, and file import is also supported. After import, the data is stored in the database, and the front end displays the data in list format.

[0119] After test cases are created, they can be executed as scheduled tasks in the task management system or executed immediately. When executed, the cloud downloads the test script to the printer for execution, and the test results are transmitted back in real time and the status is displayed on the front end.

[0120] Once the printer invokes the open interface, it sends real-time feedback to the cloud. The cloud receives the data, processes it, and renders the results onto the page for display. This includes transmissions of optical engine test results, MQTT protocol test results, lower-level machine test results, and printer status (light intensity, ultraviolet light, camera, etc.), as detailed below:

[0121] After the printer executes the test program, the PC processes the data and returns it to the cloud.

[0122] Data is parsed in the cloud, displayed in report form, and stored in a database, allowing for the tracking of historical results.
