Description:
Novel Binding Agent Removal Process
Background
Existing binder jetting processes struggle with completely removing the binder, which leads to residual carbon that affects product quality. Residual carbon, originating from the binder, poses significant challenges, particularly for reactive materials such as nickel-titanium ((NiTi) alloys and for other components requiring low carbon content. In these cases, carbon residues can adversely affect the mechanical properties and performance of the final products.
Invention Description
Researchers at the University of Toledo have developed a method for reducing the final Carbon amount in a sintered part providing uniform debinding.
Applications
-Removal of binding agents and Carbon from green parts without significantly increasing oxygen content.
Advantages
- Removes carbon from green part at thicknesses greater than 20mm
- Does not suffer from alloy segregation issues caused by current Hydrogen treatments
