Hoppener, Bruce (author)Focal laser ablation is a new, promising method to treat tumors. The current focal laser ablation approach is to insert an optical fiber into the patient using rigid needles. A side effect of this approach is that during the needle insertion, tissue damage occurs. The larger the diameter of the needle, the more tissue damage. If the diameter of...master thesis 2023

van der Windt, Bob (author)Fluid-controlled actuators are widely used in lower limb prostheses. Most fluid-controlled actuators have valves integrated into the cylinder systems and require complex manufacturing steps, making these systems expensive. A cost-effective production method for these complex actuator valve systems is 3D-printing. The goal of this research is to...master thesis 2022

Han, Sungi (author)Current large-scale additive manufacturing extruders use short reinforcing fibre-filled thermoplastic pellets, which marginally improve the mechanical performance but are too short to exploit the strength of the fibres fully. Long fibre pellets have much higher potential strength, and the development of higher strength materials could create...master thesis 2022

van Leengoed, Berend (author)Traditional manufacturing techniques for hydrogen pressure vessels have inherent constraints in the possible geometrical and structural optimisation. Using 5-axis Additive Manufacturing (AM) allows for a far greater shaping freedom. This thesis will provide a new manufacturing method for pressure vessels with 5-axis AM. Using the highly...master thesis 2022

van Montfort, Jip (author)Selecting the perfect cycling saddle can be a long and painful process trying and buying multiple saddles. Riding on the wrong type of saddle can cause various irritations and can even result in erectile dysfunction (Goldstein, 2007) and may in the end spoil the fun of cycling.<br/><br/>A direction in the design of female saddles was chosen...master thesis 2022

NTOUPAS, DIMITRIOS (author)Bioreceptivity is a natural phenomenon that has been observed on building material for many years. Bioreceptivity is when materials are being colonized by one or more species of living organisms without necessarily going under biodeterioration. (Guillitte, 1995) Based on the literature, bioreceptivity depends on three main factors: on climatic...master thesis 2022
