An experimental approach for predicting vat photopolymerization debinding cracks using machine learning

Open Ceramics
Vat photopolymerization debinding exhibits complex behavior depending on layer-by-layer deposition, scraping, lasing conditions, anisotropy of shrinkage, polymer decomposition, and shape thickness environments, making debinding cracks difficult to ...

Impact of oxygen content on debinding of binder jetted 17-4 PH stainless steel: Part I – Debinding

Powder Metallurgy
Binder jetting (BJT) utilises a sacrificial binder to shape green parts in a metal powder bed. The binder must be removed during debinding at elevated temperatures without contaminating the powder material. Efficient binder removal often requires oxygen in the atmosphere to aid the decomposition of the binder, but oxygen causes ...

Progress in Characterizing Curing and Debinding of Ceramic Inks for Stereolithography

Journal of the American Ceramic Society
ABSTRACT During ceramic stereolithography, laser photopolymerization must achieve high and uniform curing of monomers to ensure a crack‐free debinding step. In this study, we present a spatially resolved quantification of curing rate using Fourier transform infrared (FTIR) spectroscopy, relying on advanced deconvolution methods ...
