AI Technical Summary
Traditional methods for creating inner walls of multi-wall metal castings using soluble waxes or thermoset materials in ceramic cores face issues such as dimensional instability, incompatibility with ceramic core firing, and reduced core yield, limiting design flexibility and tooling complexity.
A multi-material system combining soluble wax and thermoset/photopolymer materials is used in a sacrificial fugitive, allowing for additive manufacturing to create complex inner wall structures, followed by chemical removal and thermal processing to ensure ceramic core integrity.
The multi-material system enhances ceramic core integrity and design flexibility by overcoming limitations of singular materials, enabling high-temperature stability and simplifying tooling complexity while maintaining core yield.
