Open Wedge High Tibial Osteotomy (OWHTO) is an extensively used, effective treatment option for medical conditions such as medial knee osteoarthritis and varus malalignment. The current developments in the 3D printing industry facilitated using 3D printed patient-specific guides (PSSGs), making OWHTO a desirable treatment option. Although the...

The built environment contributes in a large extend to the global greenhouse gas emissions. With a growing demand for new buildings another view on building products is required. This thesis focusses on creating a biobased sound absorbing panel made from a mycelium bound biomaterial derived from urban waste. The production method for this panel...

The use of additive manufacturing (AM) can potentially offer significant benefits to the design and performance of resistojet components but has so far only seen limited research in this application. The goal of this study was to investigate the possibility of 3D printing a functional resistojet heating chamber and the potential benefits that...

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...

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...

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...

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...

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...

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...

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...

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...

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...

Nasal airway obstruction (NAO) is one of the most common symptoms in the human respiratory system and causes a considerable financial burden to both individuals and society. Currently, NAO detection is troublesome to achieve, which can influence the accuracy and effectiveness of clinical surgery. Although several objective measurement techniques...

Background: Current challenges in the design of anthropomorphic robot fingers is the implementing of anatomically accurate tendon-ligament structures, specifically for the collateral ligaments, volar plates, and the extensor apparatus. The development of robot fingers with these structures could aid in the further understanding of the functional...

This research project is a collaboration between TUDelft, UPPS Fieldlab, and Made4eyes, a company that produces made-to-fit eyewear.<br/>In order to design a frame correctly, it is essential having a 3D head scan upon which the frame can be molded. The temple tips are crucial components that contribute to the frame's comfort and stability....

Background: In Africa, many women suffer from vesicovaginal fistulas. In this study, a phantom model for a vesicovaginal fistula repair was developed that can be produced and used in Africa, to train medical doctors in the treatment of simple fistulas by the transvaginal approach.<br/>Method of production: The phantom consists out of 3D printed...

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...

Vitrectomy is an often performed procedure during eye surgery and requires a high-precision vitreous cutter. The production of these precise and lightweight vitreous cutters sets high demands on the manufacturing process. Trained technicians must assemble the device step by step and continuously check and validate the manufacturing process....
