New Materials by Photopolymerization

CHIMIA, 1993
Despite lateral resolution being the most intensely studied topic in photopolymer research, vertical resolution properties finally add the decisive momentum to reach the desired performance in photopolymer layers. We will describe four different

Rheological Study of the Solidification of Photopolymer and Dispersed Nanotube Systems

Applied Rheology, 2011
We herein describe a set of rheological measurements that were carried out in order to characterize the solidification of photopolymers. The solidification depends on the length of time of exposure to UV light, and the intensity of that light, which ...

Digital Light Processing of Thermoplastic Poly(methyl methacrylate) Photoresin Combined With Solvent Vapor Smoothing

Advanced Engineering Materials, EarlyView.
A thermoplastic PMMA‐based photoresin enables high‐resolution DLP printing followed by solvent‐vapor smoothing. The treatment reduces staircase‐induced surface roughness from 2.33 µm to 129 nm and increases visible‐light transmittance from approximately 30% to 80%, providing a route toward transparent PMMA components for rapid prototyping and non ...
