Multiphysics modelling of the mechanical properties in polymers obtained via photo-induced polymerization

Abstract Photopolymerization is an advanced technology to trigger free radical polymerization in a liquid monomer solution through light-induced curing, during which mechanical properties of the material are significantly transformed. Widely used additive manufacturing, parts fabricated with this technique display precisions up nanoscale; however, performance final components not only affected by raw but also specific setup employed printing process. In paper, we develop multiphysics model predict photo-cured components, taking into account process parameters involved considered manufacturing technology. approach proposed, main chemical, physical, and aspects photopolymerization modelled implemented finite element framework. Specifically, kinetics light diffusion from moving source chain formation coupled statistical describe as function degree cure. Several parametric examples provided, order quantify effects settings on spatial distribution component. The proposed provides tool features additively manufactured parts, designers can adopt optimize desired characteristics products.
