de Vries, Sietse (author)Fused filament fabrication (FFF) is the most used additive manufacturing technique that uses a heated nozzle to melt a polymer and a feeder to extrude it on a buildplate. The dependencies of temperature, shear-rate, viscosity and pressure of the melt create complex dynamics within the nozzle, which causes inconsistent extrusion. To improve...master thesis 2022

Buijserd, Arjan (author)This thesis presents the development of guidance cards for consumers engaged in “3D Printing for Repair” (3DPfR). When being engaged in 3DPfR, consumers face multiple challenges, for example printing parts that can resist high temperatures, or making parts with fine details. The goal of this project was to develop guidelines which allow...master thesis 2022

Donders, Ennio (author)While Additive Manufacturing is famed for its ability to create complex geometries, sustainability of the technologies is given less attention. Due to the need to melt filament and heat up the printbed, FDM requires a considerable amount of energy. On top of that, valuable and non-renewable resources are used for the production of the commonly...master thesis 2022

Bieling, Thijs (author)Evaporation can induce acoustic emissions in microfluidic devices. The origin of these emissions and their damping remains elusive. This thesis studies acoustic emissions from 3D printed microfluidic tubes mimicking xylem vessels in plants. We show the time and frequency domain signature of these emissions. From these signatures, we identify...master thesis 2022
