deBinding
Debinding is a manufacturing step in which organic binder material is removed from a molded or printed part produced from powders such as ceramics or metals. The binder holds the powder together in the green state, and debinding prepares the part for the next stage, typically sintering, by creating a porous skeleton through which gases can escape. Debinding is common in ceramic injection molding (CIM), metal injection molding (MIM), wax-pattern investment casting, and bound-powder additive manufacturing.
There are several debinding methods, chosen based on binder chemistry and part design. Solvent debinding dissolves
Quality considerations include the uniformity of binder removal, which affects risk of cracks, blistering, or distortion,
