String Tension Support for Stable Overhang 3D Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D printing techniques fail to provide adequate physical support both to the object being printed and the 3D printer itself, leading to potential deformation due to self-weight during critical repairs or printing in unstable areas.
Innovation Solution
A method and system where a 3D printer creates appropriate force components using a string and lock-based mechanism to provide physical support to both the printer and the printed object, ensuring stability and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If physical support is added to support the printed portion, then deformation due to self-weight is prevented, but the stability of the 3D printer itself is not considered
Solution Approach 1:
The patent applies counterweight principle by introducing a support structure that provides opposing force to balance the self-weight of the printed portion. The support structure is designed to generate counteracting forces that prevent deformation of the printed object while maintaining printer stability during the printing process.
Solution Approach 2:
The patent introduces a support structure as an intermediary element between the printed portion and the printing apparatus. This mediator provides the necessary physical support to prevent deformation while also considering the stability of the printer itself, resolving the contradiction between print quality and printer stability.
2Manufacturing precision
If conventional physical support techniques are used, then object deformation is prevented, but both the object and the 3D printer are not supported simultaneously
Solution Approach 1:
The support structure is designed to perform multiple functions simultaneously: it supports the printed object to prevent deformation while also providing stability to the 3D printer. This multi-functional design resolves the contradiction by making a single structure that addresses both object shape accuracy and system stability requirements.
Solution Approach 2:
The support structure generates counteracting forces that simultaneously support both the printed object and the printer system, preventing deformation of the object while maintaining overall system stability during the printing process.
