Analysis of UV-Assisted direct ink writing rheological properties and curing degree

In this research, the relationship between the viscosity and curing degree of an acrylate-based resin under UV light was investigated by UV-rheometer and photo-DSC. The influences of different material compositions were studied with single-factor analysis. Viscosity and heat flow measurements were c...
