3D Model Rotation for Directional Strength in Lamination Fabrication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamination fabricating apparatuses do not consider the laminating direction of 3D-fabricated objects, resulting in inferior tensile strength in the vertical direction compared to the horizontal direction, leading to a lack of preferred strength in the fabricated objects.
Innovation Solution
An information processing apparatus that includes a display unit to show 3D model data, a direction receiver to input desired reinforcement directions, and a relocation unit to rotate the 3D model data, allowing for the reinforcement of 3D-fabricated objects in specific directions by converting and displaying shape data to enhance tensile strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the 3D-fabricated object is laminated from bottom up in vertical direction, then the fabrication process is simple and efficient, but the strength against tension in the vertical direction becomes lower than in the horizontal direction
Solution Approach 1:
The patent applies preliminary action by rotating the 3D model data before fabrication to pre-determine the optimal strength direction. The system calculates the principal stress direction and rotates the model accordingly before the lamination process begins, ensuring that the final fabricated object has enhanced strength in the required direction without modifying the fabrication process itself
2Ease of manufacture
If the laminating direction is fixed vertically, then the fabrication process is straightforward, but the strength direction cannot be optimized for specific application requirements
Solution Approach 1:
The patent applies dynamics by making the model orientation adjustable and adaptable. The system dynamically rotates the 3D model data based on calculated principal stress directions or user-specified requirements, allowing the fabrication process to adapt to different strength requirements while maintaining the same straightforward vertical lamination process
Solution Approach 2:
The patent applies parameter changes by modifying the orientation parameter of the 3D model data before fabrication. The system changes the rotational parameters of the model based on stress analysis or user input, enabling optimization of strength characteristics without changing the fundamental fabrication process parameters
