Effects of Solvent Debinding on the Microstructure and Properties of 3D-Printed Alumina Ceramics [PDF]
ACS Omega, 2020 Solvents assist in the debinding of stereolithography-based 3D-printed alumina green bodies. The green bodies subsequently undergo thermal debinding and sintering to obtain alumina ceramics. In this study, several solvents were tested, including polyethylene glycol, oxalic acid, ammonium hydroxide, ethyl alcohol, methyl methacrylate, butyl acetate ...

Solvent debinding kinetics and sintered properties of injection moulded 316L stainless steel powder
Powder Metallurgy, 2005 A stainless steel (316L) powder having a median particle size of ∼25 μm was injection moulded using binders composed of polyethylene glycols (PEG) and polymethylmethacrylate (PMMA). The PEG content was leached in water and debinding kinetics studied as a function temperature.

A Study of Solvent Debinding Variables on Ti6Al4V Green Bodies [PDF]
Advanced Materials Research, 2014 Debinding is one of the most critical and time consuming stage in metal injection moulding (MIM). German and Bose (1997) reported that early debinding practice relied on thermal binder degradation, requiring up to 300 hours for complete binder removal. Today multi-stage debinding techniques are introduced cutting down the debinding time to as little as
