Wu, Shang-Che (author)Current membrane fabrication processes are not sustainable as they are energy-intensive and require hazardous solvents. Additive manufacturing, due to its low waste production and the absence of harmful chemicals, can provide a more sustainable membrane manufacturing process. Up to this point, there was no way to 3D-print a membrane that meets...master thesis 2023

Putra, N.E. (author)The treatment of large bone injuries continues to be challenging partially due to the limited quantity and quality of bone-replacing materials. Iron (Fe) and its alloys have been developed as a group of load-bearing biomaterials. Recent advances in additive manufacturing (AM) have enhanced the potential of Fe-based biomaterials as biodegradable...doctoral thesis 2023

Lesueur, M.J.B.P. (author), Zhang, X. (author), Poulet, Thomas (author), Veveakis, Manolis (author)The seminal work of Gurson (J Eng Mater Technol 99:2–5, 1977) on a simplified pore structure, a single spherical pore, first provided a theoretical relationship between the yield stress and the porosity. This contribution extends the approach to determine the macroscopic yield of a porous material by taking explicitly into account its...conference paper 2023

Amin, Shashank (author)Kirigami- the Japanese art of paper cutting – is used extensively as a design philosophy for stretchable and morphable structures. An array of cuts on a thin planar sheet creates a structure that can morph into a 3D pattern on applying an in-plane uniaxial load. This type of structure is called a kirigami metasurface. A subset of this type of...master thesis 2022

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

Calis, Ilse (author)Fabricating custom-made ocular prostheses is currently a highly-skilled, labour-intense and non-reproducible process performed by an ocularist. Custom-fit prostheses are made from acrylic using a plaster mould, the iris is hand-painted, and veins are mimicked by adding red embroidery threads. Digital production techniques provide opportunities...master thesis 2022

Mulder, Jelmer (author)In the Netherlands roughly 20.000 people wear an ocular prosthetic as a consequence of losing their eye due to an accident or disease. An ocular prosthetic is a type of facial prosthesis that replaces an absent natural eye. The main goal of an ocular prosthetic is to provide an aesthetic replacement of a real eye. It does not restore the ability...master thesis 2022

Kouwenhoven, Timo (author)A novel nonlinear stiffness unit cell aided magnetic gravity compensator is proposed for the purpose of isolating low-frequency vibrations. A negative stiffness magnet setup is combined with a compliant unit cell with tailored nonlinear force-displacement characteristics. This combination offers a large range of motion featuring low stiffness, a...master thesis 2022

Firas Sameh Abdel-Karim Al-Share', FIras (author)Research about alkali-activated materials or geopolymers has increased in the past decade as they are regarded as a potential replacement to cement-based materials. This is due to the fact that alkali-activated materials possess several advantages over cement-based materials, and the most important one is that they are more sustainable to the...master thesis 2022

de Winter, Jikke (author)Biosensing properties like mass, density and stiffness on a single cell level can help diagnose diseases. Mass sensing of cells and subcellular components is typically performed with resonant microstructures. Recently such microstructures were fabricated using an emerging 3D printing technique called two-photon polymerization (2PP) contrary to...master thesis 2022

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
