[0027] None DETAILED DESCRIPTION

[0028] The present application 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 application more thorough and comprehensive.

[0029] It is to be understood that when an element such as a layer, region or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. It will be understood that, when a layer is referred to as being "formed on" another layer, it can be formed directly on the other layer or intervening layers can also be present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] The embodiments of the present application disclose a 3D printing abnormality processing method, the disclosed 3D printing abnormality processing method comprises the following steps:

[0032] Step one, in the printing process, the state information of the printing system is recorded in real time, the state information comprises a print head position, a powder spreader position, a working platform height, a current execution step state, a current printing mode and printing parameters. Specifically, in the 3D printing process, the system records the state information of the printing system in real time and comprehensively. These key information comprises but is not limited to the accurate position of the print head, the current position of the powder spreader, the height of the working platform, the specific step state of the current execution, the printing mode being used and all related printing parameters. This step provides detailed data support for subsequent abnormality processing.

[0033] Step two, when the printing process is interrupted abnormally, the abnormal state information of the printing system is encoded and recorded into a storage medium, and the system alarms the user that the printing is interrupted abnormally. At this time, once the printing process is interrupted abnormally, the system immediately encodes the current abnormal state information and safely stores the information into the designated storage medium. At the same time, the system sends an obvious alarm signal to timely inform the user that the printing job has been interrupted and prompts the specific abnormal information.

[0034] Step three, the user processes the abnormal problems related to the printer according to the system alarm prompt. Specifically, after receiving the alarm prompt of the system, the user checks and maintains the printer according to the provided abnormal information to solve the specific problems leading to the interruption.

[0035] Step four, after the user handles the exception, it is judged whether the print processing can be continued according to the specific exception problem, if the judgment result is yes, the print processing is continued. Specifically, after the user handles the exception, it is carefully judged whether the print job has the condition of print processing according to the nature and severity of the exception. If the judgment result is yes, the print processing is continued.

[0036] Step five, the print system selects and executes the corresponding exception interrupt processing strategy based on the recorded exception state code information, if the exception processing flow execution process is normal, the print processing is continued, if the exception processing flow execution process occurs again, the user is prompted and the print processing is terminated. Specifically, after the system receives the print processing instruction, the corresponding exception interrupt processing strategy is intelligently selected and executed according to the recorded exception state code information. If the exception processing flow is executed smoothly, the system will continue to execute the print processing flow and recover the print job; if the processing process occurs again, the system will send an alarm signal again and terminate the current print processing flow, avoiding further loss.

[0037] From the foregoing, it can be seen that the 3D printing exception processing method disclosed in the embodiment of the application significantly improves the stability and reliability of the 3D printing job through a series of finely designed steps. The comprehensive state information of the printing system is recorded in real time during the printing process, including the key position information of the print head, the powder spreader and the work platform, and the printing parameters, etc., which provides detailed data basis for subsequent exception processing. This helps to quickly locate the problem source and reduce the troubleshooting time. Once the exception interrupt occurs, the system can immediately encode and record the exception state information, and send an alarm signal, so that the user can quickly know and handle the exception. This instant response mechanism effectively avoids the further deterioration of the problem and reduces the potential loss. After the user handles the exception, the system can intelligently judge whether the print processing can be continued according to the recorded exception state information. If the condition is met, the system automatically selects and executes the corresponding processing strategy to recover the print job. This not only improves the printing efficiency, but also maximizes the waste of the printed part.

[0038] In the embodiment of the present application, the abnormal problem in step four needs to be handled within the preset process requirement time, if it exceeds the preset process time, the printing instruction cannot be continued. Specifically, in the 3D printing process, if some abnormal problems are not handled in time, more serious consequences may be caused, such as material solidification, equipment overheating, etc. By setting the preset process requirement time, the present application ensures that the user can respond and handle the abnormal problem in the shortest time, thereby effectively avoiding the printing failure or equipment damage caused by time delay. By introducing the preset process requirement time to limit the processing time of the abnormal problem, the practicability and reliability of the 3D printing abnormal handling method are further improved, and a more efficient and safe printing experience is provided for the user.

[0039] Further, the encoding method in step two encodes each abnormal state information with a unique identifier to ensure the uniqueness and traceability of the abnormal state information. At this time, by encoding the abnormal state information with a unique identifier, the accuracy and traceability of the 3D printing abnormal handling method are further improved, and a more efficient and accurate printing abnormal handling experience is provided for the user. This innovative design not only helps to reduce the abnormal loss in the printing process, but also provides strong support for the continuous improvement and optimization of the printing technology.

[0040] Optionally, the abnormal state information in step two can include printing inkjet abnormality, powder laying abnormality, work platform lifting abnormality, print head moving abnormality, powder laying device moving abnormality, liquid or powder adding abnormality, print head cleaning abnormality, and powder laying device cleaning abnormality. Of course, the abnormal state information can also be other fault information, and the embodiment of the present application does not limit this.

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

Once the printing is interrupted, the encoding module encodes the abnormal state and records the abnormal state, while triggering an alarm to guide the user to process in time. After the user solves the abnormality according to the guidance of the alarm processing module, the abnormal problem judging module evaluates the feasibility of printing continuation. If the conditions are met, the continuation processing module selects and executes a corresponding processing strategy according to the abnormal state encoding, and ensures seamless connection of the printing work.
