3D Molding Support Data from User-Selected Overhang Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for automatically setting support structures in three-dimensional molded objects often fail to reflect the user's desired support structure, necessitating inefficient manual adjustments.
Innovation Solution
A data generation method that includes displaying an overhang section, receiving user selection of a first region, determining a second region based on characteristic angles, and generating support structures to reflect the user's desired support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If support structure is set automatically, then productivity is improved, but user's desired support structure cannot be reflected
Solution Approach 1:
The support structure setting process is segmented into automatic region determination (based on overhang analysis) and user selection phases. The system divides the support structure into multiple candidate regions and presents them for user selection, allowing both automated efficiency and user customization.
Solution Approach 2:
The system performs preliminary automatic analysis to identify candidate support regions based on overhang characteristics before presenting options to the user. This preliminary action reduces the user's workload from creating support structures from scratch to simply selecting from pre-analyzed candidates.
2Ease of operation
If support structure is set manually, then user's desired support structure can be reflected, but productivity deteriorates
Solution Approach 1:
The system performs preliminary automatic analysis to identify candidate support regions based on overhang characteristics before presenting options to the user. This preliminary action reduces the user's workload from creating support structures from scratch to simply selecting from pre-analyzed candidates.
Solution Approach 2:
The system automatically performs the complex analytical work of identifying support regions based on overhang analysis, saving the user from performing this tedious manual analysis while still allowing user input for final selection.
3Manufacturing precision
If complete manual setting is required, then accuracy of user preference is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary automatic analysis to identify candidate support support regions based on overhang characteristics before presenting options to the user. This preliminary action reduces the user's workload from creating support structures from scratch to simply selecting from pre-analyzed candidates.
Solution Approach 2:
The system provides visual feedback by displaying candidate support regions on the display section, allowing users to verify and adjust the automatically determined regions. This feedback mechanism ensures accuracy while maintaining efficiency.
Data Source
AI summary
A data generation method for generating molding data for molding a three dimensional molded object by ejecting a molding material onto a molding surface of a stage to stack layers of the molding material, the data generation method includes a receiving step of displaying at least a part of an overhang section of the three dimensional molded object on a display section and receiving selection of a first region representing at least a part of the overhang section on the display section; a region determining step of determining a second region representing at least a part of the overhang section based on a characteristic amount of the selected first region; and a generating step of generating data representing a support structure for supporting the determined second region from below in a stacking direction of the layers. The characteristic amount includes a characteristic angle representing an angle of the first region with respect to the molding surface.
