Description

Technical Field

[0001] The present invention relates to the technical field of printing methods, and in particular to a 3D printing exception processing method and system. Background Art

[0002] 3DP (three-dimensional powder bonding) printing technology, as a cutting-edge powder-based additive manufacturing technology, has shown great potential in the manufacturing industry with its unique way of building three-dimensional entities layer by layer. The technology gradually shapes complex three-dimensional structures by laying powder materials layer by layer on a work platform and using a binder to accurately bond specific areas in each layer.

[0003] However, in actual applications, 3DP printing jobs may suddenly stop due to a variety of reasons, such as external environmental interference, mechanical failure, electrical system instability, software abnormality, or material supply interruption. Such interruptions not only cause the completed printed parts to be damaged due to the inability to continue to solidify, but also cause a huge waste of time and resources, while extending the entire production cycle. Summary of the invention

[0004] Based on this, it is necessary to provide a 3D printing exception handling method and system to address the problem that the current 3D printing system suddenly stops for unknown reasons, causing a huge waste of time and resources.

[0006] In a first aspect, an embodiment of the present invention discloses a 3D printing exception handling method, comprising:

[0007] Step 1: During the printing process, the status information of the printing system is recorded in real time, and the status information includes the print head position, the powder spreader position, the work platform height, the current execution step status, the current printing mode and the printing parameters;

[0008] Step 2: When the printing process is abnormally interrupted, the abnormal status information of the printing system is encoded and recorded in the storage medium, and the system alarms to remind the user that the printing is abnormally interrupted;

[0020] The abnormal problem judgment module, after the abnormal problem judgment module user completes the abnormality processing, judges whether the continuous printing processing can be performed according to the specific abnormal problem, and if the judgment result is yes, sends the continuous printing instruction;

[0021] The continuation processing module is used for the printing system to select and execute the corresponding exception interruption processing strategy based on the recorded abnormal status coding information. If the execution process of the exception processing flow is normal, the continuation printing process will continue to be executed; if an exception occurs again during the execution process of the exception processing flow, an alarm will be issued to prompt the user and the continuation exception processing flow will be terminated.

[0022] In a third aspect, an embodiment of the present invention discloses a computer, including:

[0023] A memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the 3D printing exception handling method according to any one of claims 1 to 5 by executing the computer instructions.

[0027] none DETAILED DESCRIPTION

[0028] The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a centered element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a centered element at the same time. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom end", "top end" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] The embodiment of the present invention discloses a 3D printing exception handling method, and the disclosed 3D printing exception handling method includes:

[0032] Step 1: During the printing process, the status information of the printing system is recorded in real time, and the status information includes the position of the print head, the position of the powder spreader, the height of the work platform, the status of the currently executed step, the current printing mode, and the printing parameters. Specifically, during the 3D printing process, the system records the status information of the printing system in real time and comprehensively. These key information include, but are not limited to, the precise position of the print head, the current position of the powder spreader, the height of the work platform, the status of the specific step currently being executed, the printing mode being used, and all relevant printing parameters. This step provides detailed data support for subsequent exception handling.

[0033] Step 2: When the printing process is abnormally interrupted, the abnormal status information of the printing system is encoded and recorded in the storage medium. At the same time, the system alarms to remind the user that the printing is abnormally interrupted. At this time, once the printing process is abnormally interrupted, the system immediately encodes the current abnormal status information and stores this information safely in the designated storage medium. At the same time, the system sends out an obvious alarm signal to promptly notify the user that the printing job has been interrupted and prompts specific abnormal information.

[0034] Step 3: The user handles the printer-related abnormality according to the system alarm prompt. Specifically, after receiving the system alarm prompt, the user performs necessary inspection and maintenance on the printer according to the abnormality information provided to solve the specific problem that caused the interruption.

[0035] Step 4: After the user handles the exception, it is determined whether the printing can be continued according to the specific exception. If the judgment result is yes, a continued printing instruction is sent. Specifically, after the user handles the exception, it is determined carefully whether the print job meets the conditions for continued printing according to the nature and severity of the exception. If the judgment result is positive, a continued printing instruction is sent to the system.

[0036] Step 5. The printing system selects and executes the corresponding abnormal interruption handling strategy based on the recorded abnormal status coding information. If the execution process of the abnormal handling process is normal, the continuation printing process will continue to be executed; if an abnormality occurs again during the execution of the abnormal handling process, an alarm will be issued to the user and the continuation abnormal handling process will be terminated. Specifically, after receiving the continuation printing instruction, the system intelligently selects and executes the corresponding abnormal interruption handling strategy based on the previously recorded abnormal status coding information. If the abnormal handling process is executed smoothly, the system will continue to execute the continuation printing process and resume the printing job; if an abnormality occurs again during the processing, the system will issue an alarm signal again and terminate the current continuation abnormal handling process to avoid further losses.

[0037] It can be seen from the above that the 3D printing exception handling method disclosed in the embodiment of the present invention significantly improves the stability and reliability of 3D printing operations through a series of carefully designed steps. During the printing process, the comprehensive status information of the printing system is recorded in real time, including the key position information of the print head, powder spreader, work platform, and printing parameters, etc., providing a detailed data basis for subsequent exception handling. This helps to quickly locate the source of the problem and reduce the troubleshooting time. Once an abnormal interruption occurs, the system can immediately encode and record the abnormal status information, and issue an alarm signal at the same time, so that the user can quickly learn about and handle the exception. This immediate response mechanism effectively avoids further deterioration of the problem and reduces potential losses. After the user handles the exception, the system can intelligently determine whether printing can be continued based on the recorded abnormal status information. If the conditions are met, the system automatically selects and executes the corresponding processing strategy to resume the printing job. This not only improves printing efficiency, but also minimizes the waste of the printed part.

[0038] In an embodiment of the present invention, the abnormal problem in step four needs to be handled within the preset process requirement time. If the preset process time is exceeded, the printing instruction cannot be continued. Specifically, during the 3D printing process, certain abnormal problems may lead to more serious consequences such as material solidification, equipment overheating, etc. if they are not handled in a timely manner. By setting the preset process requirement time, the present invention ensures that users can respond to and handle abnormal problems in the shortest time, thereby effectively avoiding printing failures or equipment damage caused by time delays. By introducing the preset process requirement time to limit the time for handling abnormal problems, the practicality and reliability of the 3D printing abnormality handling method are further improved, providing users with a more efficient and safe printing experience.

[0039] Furthermore, the encoding method in step 2 uses a unique identifier to encode each abnormal state information to ensure the uniqueness and traceability of the abnormal state information. At this time, by using a unique identifier to encode the abnormal state information, the accuracy and traceability of the 3D printing abnormality handling method are further improved, providing users with a more efficient and accurate printing abnormality handling experience. This innovative design not only helps to reduce abnormal losses during the printing process, but also provides strong support for the continuous improvement and optimization of printing technology.

[0040] Optionally, the abnormal status information in step two may include printing inkjet abnormality, powder spreading abnormality, work platform lifting abnormality, print head movement abnormality, powder spreader movement abnormality, liquid or powder addition abnormality, print head cleaning abnormality and powder spreader cleaning abnormality. Of course, the abnormal status information may also be other fault information, which is not limited to the embodiments of the present invention.

[0041] In an optional embodiment, when the printing system in step five selects and executes the abnormal interruption handling strategy, if the system records multiple abnormal state coding information at the same time, the system needs to process each abnormal state coding information separately. In this case, by intelligently processing multiple abnormal state coding information, the flexibility and comprehensiveness of the 3D printing abnormality handling method are further improved, providing users with a more efficient, accurate and reliable printing abnormality handling experience. This innovative design not only helps to reduce abnormal losses during the printing process, but also provides strong support for the continuous improvement and optimization of printing technology.

[0042] Based on the 3D printing exception handling method disclosed in the embodiment of the present invention, the embodiment of the present invention further discloses a 3D printing exception handling system, which is applied to the 3D printing exception handling method described in any embodiment above. The 3D printing exception handling system includes:

[0043] Recording module, the recording module is used to record the status information of the printing system in real time during the printing process, the status information includes the print head position, the powder spreader position, the working platform height, the current execution step status, the current printing mode and the printing parameters;

[0044] The encoding module is used to encode the abnormal status information of the printing system and record it in the storage medium when the printing process is abnormally interrupted, and the system alarms to remind the user that the printing is abnormally interrupted;

[0045] An alarm processing module, wherein the user of the alarm processing module processes printer-related abnormal problems according to system alarm prompts;

[0046] The abnormal problem judgment module, after the abnormal problem judgment module user completes the abnormality processing, judges whether the continuous printing processing can be performed according to the specific abnormal problem, and if the judgment result is yes, sends the continuous printing instruction;

[0047] The continuation processing module is used for the printing system to select and execute the corresponding exception interruption processing strategy based on the recorded abnormal status coding information. If the execution process of the exception processing flow is normal, the continuation printing process will continue to be executed; if an exception occurs again during the execution process of the exception processing flow, an alarm will be issued to prompt the user and the continuation exception processing flow will be terminated.

[0048] It can be seen from the above content that the 3D printing exception handling system disclosed in the embodiment of the present invention realizes comprehensive monitoring and efficient processing of abnormal states in the 3D printing process by integrating a recording module, an encoding module, an alarm processing module, an abnormal problem judgment module and a continuation processing module. The recording module captures the key status information of the printing system in real time and provides data support for exception handling. Once printing is interrupted, the encoding module quickly encodes and records the abnormal state, and triggers an alarm to guide the user to handle it in time. After the user solves the abnormality according to the guidance of the alarm processing module, the abnormal problem judgment module evaluates the feasibility of continuing printing. If the conditions are met, the continuation processing module selects and executes the corresponding processing strategy according to the abnormal state code to ensure seamless connection of the printing job. If an abnormality is encountered again during processing, the system will immediately alarm and terminate the continuation, effectively ensuring the stability and reliability of the printing job.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
