Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional modeling apparatuses with multiple modeling heads face issues of lower dimensional precision and strength due to uncalibrated horizontal positions, leading to misalignment and contamination.
Innovation Solution
A three-dimensional modeling apparatus with a control unit that controls two modeling heads to model first and second calibration members with specific intervals, using a camera and display unit to calibrate their positions, and a movement mechanism to adjust alignment.

Engineering Contradiction Analysis
1Productivity
If multiple modeling heads are provided to increase productivity, then productivity is improved, but manufacturing precision deteriorates due to uncalibrated horizontal positions
Solution Approach 1:
The patent applies preliminary action by performing calibration of multiple modeling heads before actual production modeling. The control unit controls each modeling head to model calibration members with specific patterns (first calibration member with narrow intervals, second calibration member with wide intervals) on the stage. This preliminary calibration establishes accurate positional relationships between multiple modeling heads, ensuring that when they subsequently work together on production pieces, they maintain proper alignment and achieve high dimensional precision while preserving the productivity benefits of having multiple heads.

Solution Approach 2:
The patent applies feedback by using imaging units to capture images of the calibrated members and automatically calculating positional relationships. The system images the first and second calibration members, processes these images to determine the actual positions of modeling heads, and uses this feedback information to correct and optimize the positioning of each modeling head. This closed-loop feedback mechanism ensures accurate alignment between multiple modeling heads, preventing misalignment and contamination issues that would otherwise compromise the strength of modeled objects.

AI summary
A movement mechanism relatively moving at least one of a first modeling head and a second modeling head and a stage, and a control unit controlling the first modeling head, the second modeling head, and the movement mechanism are provided. The control unit controls the first modeling head to execute modeling of a first calibration member on the stage and the second modeling head to execute modeling of a second calibration member on the stage, the first calibration member has a plurality of modeling lines placed at first intervals in a first direction on the stage, and the second calibration member has a plurality of modeling lines placed at second intervals larger than the first intervals in the first direction on the stage.
