Additive Manufactured Fired Body Support to Suppress Firing Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In powder additive manufacturing, deformation occurs in additive manufactured objects during drying and firing processes, which is a concern, especially for precision casting applications.
Innovation Solution
A supporter is manufactured using the same powder material as the additive manufactured object to surround it, suppressing deformation during drying and firing by ensuring the additive manufactured object and supporter are not joined and using an interference material to prevent contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a supporter is manufactured using the same powder material as the additive manufactured object, then the supporter can effectively suppress deformation during drying and firing, but the supporter and additive manufactured object may join together during firing
Solution Approach 1:
The patent introduces a release agent as an intermediary substance between the supporter and the additive manufactured object. This release agent prevents direct contact and bonding between the two components during the firing process, while still allowing the supporter to effectively suppress deformation of the additive manufactured object. The release agent acts as a mediator that maintains the functional relationship of support while preventing the harmful joining effect.
2Ease of manufacture
If the additive manufactured object is dried and fired without a supporter, then the manufacturing process is simpler, but deformation occurs in the additive manufactured object during drying and firing
Solution Approach 1:
The patent combines the manufacturing of the supporter and the additive manufactured object into a single simultaneous additive manufacturing process. Both components are fabricated together in the same build process using the same powder material, which simplifies the overall manufacturing process compared to creating the supporter separately and then assembling it. This merging approach maintains manufacturing simplicity while providing the deformation suppression benefits of having a supporter present throughout the drying and firing processes.
3Manufacturing precision
If the supporter completely surrounds the additive manufactured object, then deformation suppression is maximized, but removal of the supporter after firing becomes difficult
Solution Approach 1:
The release agent serves as an intermediary that facilitates easy separation between the supporter and the additive manufactured object after firing. By preventing direct bonding during the firing process, the release agent allows the supporter to be removed cleanly without damaging the finished product, thus resolving the contradiction between maximum support during manufacturing and easy removal afterward.
