In this study, the planar extrudateswelling of power-law and Oldroyd-B fluidsare investigated. Our numerical predictionsare in good agreement with the other resultsavailable in the literature. In addition, asimplified two-dimensional model of fusedfilament fabrication that provides details ofthe flow in the gap between the printinghead and the substrate is presented. Thenumerical simulations use thestreamfunction/log-conformation and thevolume-of-fluid methods.
