Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional printing processes often result in unintended deformation of objects due to manufacturing procedures and material choices, making it challenging to produce objects that closely resemble their requested designs.
Innovation Solution
A method involving the insertion of markers into 3D object models to monitor and adjust the printing process, allowing for real-time comparison and correction of deviations, thereby reducing deformation and improving the accuracy of the final product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3D printing processes are used to manufacture objects, then custom parts can be generated with design flexibility, but unintended deformation occurs during and after generation
Solution Approach 1:
The patent applies preliminary action by inserting markers into the 3D model before the printing process begins. These markers serve as reference points that allow for pre-planned monitoring and correction strategies. The system prepares correction data in advance based on expected deviations, enabling proactive rather than reactive deformation management.
Solution Approach 2:
The patent implements feedback mechanisms by continuously monitoring the 3D printing process through comparison of scanned marker positions against the original model. The system generates correction data based on detected deviations and feeds this information back to adjust subsequent printing operations, creating a closed-loop control system that actively compensates for deformation.
2Manufacturing precision
If markers are inserted into the 3D model for monitoring, then deformation can be detected and corrected, but the model design complexity increases
Solution Approach 1:
The patent applies local quality by placing markers only at specific critical locations on the 3D model rather than throughout the entire structure. This selective placement provides sufficient deformation monitoring information while minimizing the added complexity to the overall model design. The markers are strategically positioned to capture the most relevant deformation patterns.
3Manufacturing precision
If real-time monitoring and correction is implemented, then the accuracy of the final product improves, but the printing process time increases
Solution Approach 1:
The patent applies partial action by implementing monitoring and correction at strategic intervals during the printing process rather than continuously at every layer. The system determines when correction is most beneficial and applies adjustments selectively, reducing the overall time penalty while maintaining sufficient accuracy. Not all deviations require correction, and the system identifies which ones do.
