Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time error detection and correction is implemented using a scanner and computer system, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where a scanner detects printing errors in real-time, the computer calculates deviations between actual and planned surface information, and command information is corrected and re-transmitted to the controller. This closed-loop feedback mechanism continuously monitors and adjusts the printing process, resolving the contradiction by automatically improving precision through systematic error compensation rather than manual intervention.
Solution Approach 2:
The computer acts as an intermediary between the scanner and the controller, processing the detected surface information, calculating printing errors, generating corrected command information, and transmitting it back to the controller. This intermediary component coordinates the interaction between detection and control systems, enabling precision improvement while managing system complexity through structured information processing.
2Manufacturing precision
If continuous monitoring and correction of printing errors is performed, then manufacturing precision is improved, but loss of time increases due to error detection and processing
Solution Approach 1:
The patent enables continuous error detection and correction during the printing process without interrupting the overall operation. The scanner continuously scans the printed surface, the computer continuously processes the data and generates corrections, and the controller continuously adjusts the printing parameters. This continuous operation maintains productivity while improving precision, as the correction process is integrated into the printing workflow rather than being performed as separate post-processing steps.
3Productivity
If automated error detection and correction system is implemented, then productivity is improved by reducing manual intervention, but device complexity increases
Solution Approach 1:
The printing system performs self-diagnosis and self-correction through the integrated scanner and computer system. The scanner automatically detects printing errors, the computer automatically calculates deviations and generates corrected command information, and the controller automatically adjusts the printing process. This self-service capability eliminates the need for manual inspection and intervention, improving productivity while managing complexity through automated routines that execute without human input.

AI summary
The present disclosure relates to a method of controlling a 3D printer for construction which prints and forms various structures, in which a controller 10 configured to control the 3D printer for construction, a scanner 30 configured to detect stereographic surface information, and a computer 40 connected to the controller 10 and the scanner 30 are provided so that the scanner 30 detects actually measured surface information 39 of a printing matter 20 and transmits the detected actually measured surface information 39 to the computer 40, and the computer 40 compares the actually measured surface information 39 with planned surface information 49 to calculate a printing error and then corrects command information 19 such that the printing error is compensated for and transmits the corrected command information 19 to the controller 10. Through the present disclosure, in forming a structure using the 3D printer for construction, an error of the printing matter 20 may be quickly identified in real time, and also a setting value of the controller 10 of the 3D printer for construction may be immediately adjusted based on the identified error.
