Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional shaped object manufacturing devices face challenges in achieving high dimensional accuracy due to difficulties in detecting friction and damage during layer formation, leading to irregularities in layer thickness.
Innovation Solution
A three-dimensional shaped object manufacturing device equipped with a distance detecting unit to monitor the distance from a reference position to the layer forming unit, allowing for adjustments in layer thickness and position to ensure precise layer formation, using a shaping section with a vertically movable stage and a layer forming unit such as a squeegee or roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional three-dimensional shaped object manufacturing devices are used, then the manufacturing process can proceed without additional detection equipment, but the dimensional accuracy of the manufactured object deteriorates due to undetected friction and damage during layer formation
Solution Approach 1:
The distance detecting unit detects the distance from the layer forming unit to the shaping section before layer formation occurs, allowing for preliminary detection of friction and damage conditions. This enables adjustment of layer formation parameters in advance to prevent dimensional accuracy deterioration.
Solution Approach 2:
The system continuously detects the distance between the layer forming unit and shaping section during the layer formation process, providing real-time feedback on friction and damage conditions. This feedback is used to dynamically adjust layer formation parameters, ensuring consistent dimensional accuracy throughout manufacturing.
2Manufacturing precision
If the layer forming unit operates without distance detection, then the device structure remains simple, but the layer thickness uniformity deteriorates due to undetected friction and damage
Solution Approach 1:
The distance detecting unit performs detection before layer formation to establish baseline conditions, allowing the system to prepare appropriate layer formation parameters in advance. This preliminary measurement ensures that friction and damage are accounted for before they affect layer thickness.
Solution Approach 2:
Real-time distance detection during layer formation provides continuous feedback on the actual gap between the layer forming unit and shaping section. This feedback enables dynamic adjustment of formation parameters to compensate for friction and damage, maintaining uniform layer thickness throughout the process.
