Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing additive manufacturing methods face challenges in securely attaching and easily detaching thin plates without distortion during the production of three-dimensional objects, as they are prone to damage and require complex fixation systems.
Innovation Solution
A manufacturing method involving a fixing plate with adhesive injection holes is used to securely attach a thin plate to a build table, allowing for easy integration with solidified layers and subsequent detachment using a removing agent, minimizing the risk of distortion or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a thin plate is directly fixed to a build table, then the plate thickness can be reduced, but the plate is difficult to fix securely and may distort during additive manufacturing
Solution Approach 1:
A fixing plate is introduced as an intermediary component between the thin plate and the build table. The fixing plate provides a stable mounting surface with multiple holes for secure attachment, while the thin plate is mounted on top of it. This mediator allows the use of thin plates without compromising fixation stability during additive manufacturing.
2Reliability
If adhesive is used to attach the thin plate to the fixing plate, then secure attachment is achieved, but detachment after manufacturing becomes difficult and may damage the plate
Solution Approach 1:
The adhesive properties are changed by using a removable adhesive that can be detached with a removing agent. The adhesive provides strong attachment during additive manufacturing but can be easily removed afterward using the removing agent, allowing the thin plate to be detached without damage. This parameter change enables both secure attachment and easy detachment.
3Manufacturing precision
If multiple holes are formed in the fixing plate for adhesive injection, then attachment quality improves, but the fixing plate structure becomes more complex
Solution Approach 1:
The fixing plate is segmented with multiple holes distributed across its surface. These holes divide the adhesive injection process into multiple localized points, ensuring uniform adhesive distribution across the thin plate. The segmentation of the fixing plate structure into a pattern of holes simplifies the overall design while achieving precise adhesive application.

AI summary
A manufacturing method of a three-dimensional object includes: a positioning step, an adhering step, a placing step, an additive manufacturing step, and a detaching step. In the positioning step, a fixing plate in which adhesive injection holes are formed is placed on a thin plate, and the thin plate is positioned on the fixing plate. In the adhering step, an adhesive is dripped to the adhesive injection holes, and the fixing plate is adhered to the thin plate. In the additive manufacturing step, a three-dimensional object in which the thin plate and a solidified layer are integrated is formed. In the detaching step, adhesion between the thin plate and the fixing plate is removed by a removing agent corresponding to the adhesive.
