Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceramic stereolithography 3D printing technologies face difficulties in effectively cleaning high-yield-stress ceramic materials from complex structures due to their spatial three-dimensional net structure, which limits the removal of materials from both the surface and internal structures, especially in micro/porous designs.
Innovation Solution
A cleaning liquid composed of isobornyl acrylate, N-acrylylmorpholine, 2-Hydroxyethyl methacrylate, and 3-ethyl-3-oxetanemethanol as main cleaning agents, combined with Dispers 750W, Dispers 655, Tego 688, and Tego 755 as auxiliary agents, is used to damage the spatial mesh structure of high-yield-stress ceramic materials, allowing for the flow and removal of components, employing ultrasonic or spray cleaning methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cleaning methods are used on high-yield-stress ceramic materials, then the cleaning process is simple, but the cleaning effectiveness is poor due to the spatial three-dimensional net structure
Solution Approach 1:
The patent changes the chemical parameters of the cleaning liquid by selecting specific solvents (ethyl acetate, acetone, ethanol) and controlling their volume ratios (50-90%, 5-30%, 5-30% respectively) to effectively dissolve and remove high-yield-stress ceramic materials from the spatial three-dimensional net structure without requiring complex cleaning equipment
Solution Approach 2:
The cleaning liquid acts as an intermediary substance that mediates between the cleaning requirement and the spatial three-dimensional net structure. The specific solvent composition penetrates and dissolves the ceramic material bound in the mesh structure, enabling effective cleaning while maintaining a simple cleaning process
2Productivity
If existing cleaning liquids are used, then the cleaning process is straightforward, but they cannot effectively remove high-yield-stress ceramic materials from complex structures
Solution Approach 1:
The patent optimizes the composition parameters of the cleaning liquid by specifying precise volume ratio ranges for each solvent component. This parameter optimization enables high cleaning efficiency for complex structures while maintaining ease of operation through a straightforward application process without requiring specialized equipment or complex procedures
3Manufacturing precision
If slurry cleaning methods are applied to high-yield-stress ceramic materials, then the cleaning approach is familiar, but it fails to account for the different spatial stereoscopic mesh structure
Solution Approach 1:
The patent applies local quality by tailoring the cleaning liquid composition specifically for high-yield-stress ceramic materials with spatial stereoscopic mesh structures. The customized solvent mixture (ethyl acetate, acetone, ethanol in specific ratios) addresses the unique properties of this material structure, achieving effective cleaning while maintaining operational simplicity
Solution Approach 2:
The patent changes the chemical composition parameters to match the specific requirements of high-yield-stress ceramic materials. By adjusting the solvent types and their volume ratios, the cleaning liquid is optimized to effectively remove material from the spatial mesh structure without requiring complex cleaning methods
