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...

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...

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...

Overheating is a major issue especially in metal Additive Manufacturing (AM) processes, leading to poor surface quality, lack of dimensional precision, inferior performance and/or build failures. A 3D density-based topology optimization (TO) method is presented which addresses the issue of local overheating during metal AM. This is achieved...

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...

Venously printed contributes to the field of HCI and digital manufacturing by exploring the scope and possibilities for programmable and responsive fluidic interfaces, using multi-material 3D printing as a manufacturing technique. Novel meta-materials and computational composites have proven to open up new design paradigms and continue to expand...

The research investigates the creation of an end-effector capable of pick-and-placing thin laminates of various materials. The chosen end-effector design induces a pressure differential with a membrane, and is capable to achieve a large switching force for various delicate and geometric complex laminates. The concept utilizes an array of holes,...

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...

Laser powder bed fusion (L-PBF) is an additive manufacturing (AM) technology that has been gaining a lot of interest as it allows to produce parts with complex geometries and eliminate expensive tooling. Unlike the conventional manufacturing processes where material is removed to make the final component; AM part is manufactured layer-wise as...

Medical technology has seen great progress over the last centuries, developing increasingly more specialised therapy to benefit human health. The rise of the pharmaceutical industry and the research it drives are contributors to this success. However, in humanity's attempt to tackle more and more complex health issues, the conventional methods...

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....

Millions of people around the globe receive orthopedic implants every year. These implants help people to regain their mobility and contribute tremendously to improve the quality of life. However, a significant number of patients suffer from complications, such as implant associated infections (IAI) and aseptic loosening. The number of...

Concrete is the most used building material in the world. Its success can be linked back to its mouldability, durability and low cost. Unfortunately, current conventional concrete pedestrian bridge designs do not benefit from these key features and still require bulky shaped cross-sections, whereby part of the concrete does not contribute to the...

<br/>Additive manufacturing (AM) is quickly becoming one of the more popular methods to manufacture components made of Ti-6Al-4V in the aerospace and automobile industry due to its flexibility in producing complex geometries and reducing tooling costs. As the world of additive manufacturing is still relatively young, there is no globally...

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...

When treating a Chronic Total Occlusion (CTO) via Percutaneous Coronary Intervention (PCI), a guidewire first needs to be passed through or around the occlusion, a task requiring considerable skill and clinician experience. Proper backup support for the guidewire being used by the clinician is a prerequisite to prevent buckling or uncontrolled...

The building stock and the construction industry combined are responsible for a large share of greenhouse gases emissions. At the same time, every year tons of wood, paper and agricultural residues are wasted instead of recycled and upcycled into the production chain. In the fabrication field, the relevance of additive manufacturing processes is...

With a building industry that is responsible for a large amount of our carbon emissions, a rising population, and the over-extraction of resources, architects and engineers have the responsibility to use environmentally friendly products. Lignin and cellulose are the most abundant biopolymers on earth and produce a lot of waste by ending up...
