Solution Overview
Problem
Existing build systems face challenges in accurately building three-dimensional structural objects using powder-like materials, as they struggle to precisely position and align the build objects on a workpiece, leading to inconsistencies in the final product.
Innovation Solution
A build system that incorporates a display apparatus to show images of the object and designated positions, an input apparatus for user input, and a build apparatus that uses this information to accurately position and build the object, along with a support apparatus, additive processing, and position measurement to ensure precise alignment and deposition of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a build system uses powder-like materials with an energy beam to build three-dimensional structural objects, then the manufacturing capability is improved, but the positioning accuracy and alignment precision deteriorate
Solution Approach 1:
The system performs preliminary actions by displaying images of the workpiece and build object before construction, allowing users to designate positions and review alignment in advance. This pre-positioning and visual confirmation step ensures accurate placement before the actual additive manufacturing begins, resolving the positioning accuracy issue while maintaining manufacturing capability.
Solution Approach 2:
The build system implements feedback by displaying real-time images of the workpiece and build object during the manufacturing process. Users can observe the construction progress and make adjustments to positioning and alignment based on visual feedback, ensuring high manufacturing precision while continuing additive manufacturing operations.
2Device complexity
If the build system relies on manual positioning methods, then the device complexity is reduced, but the alignment precision and consistency worsen
Solution Approach 1:
The system uses digital images as copies of the workpiece and build object to represent their physical positions and geometries. These visual copies allow for precise digital positioning and alignment planning without requiring complex physical positioning mechanisms, maintaining system simplicity while achieving high alignment precision through software-based control.
Solution Approach 2:
The build system replaces manual mechanical positioning with an automated visual system that uses displayed images and digital designations. Instead of relying on complex mechanical alignment tools, the system substitutes a visual-digital interface where users designate positions based on displayed images, achieving high alignment precision with reduced mechanical complexity.
