Abstract
The introduction of additive manufacturing (AM) techniques is revolutionizing the field of polymer processing, as it provides a unique alternative to produce three-dimensional shapes and highly personalized structures. [1] Among different (AM) techniques, Vat photopolymerization, material jetting and binder jetting technologies rely on photo cross-linkable resins. Thus, Photo rheometry has gained attention as it appears as an essential tool to understand the material behaviour in the process and the development of new feedstock materials. In essence, photo rheometry measurements permit to analyse rheological behaviour of materials during photochemical processes, mainly cross-linking reactions.
In this work, we present the analysis of the rheological performance of waterborne polyurethanes containing acrylate groups as a proof of concept for its incorporation as feedstock materials for Vat photopolymerization [2].
