Objective: The objective of this study was to develop and evaluate a 3D printed hydraulic actuation system, applied in a multi-articulate upper limp prosthesis. The prosthesis was designed to produce sufficient pinch force to be competitive with comparable devices (30 N), and weigh less than a human hand (<0.43 kg). The actuator should...

Building habitats on the Moon is required for long-duration missions foreseen in the very near future. The availability of lunar regolith will allow to manufacture such in space habitats and reduce the cost of space missions. However, the Moon has specific environmental characteristics that are different compared to terrestrial habitats:...

Powder bed fusion (PBF) is a widely used metal additive manufacturing method where a part is built with almost no limitation on its geometrical layout. However, parts built by PBF typically suffer from distortions and residual stresses which depend on the PBF processing conditions and the geometrical layout of the part. In order to investigate...

This research mainly investigates the relationship between the process condition, the microstructural evolution and the mechanical properties of the low carbon S690 steel in complex WAAM deposited structures. Besides, the optimum process parameters for improving the quality of the multi-pass multi-layer structure are also the research topic in...

When designing for structural performance, the geometry of the load-bearing elements is crucial for achieving the required stability. This is even more important in structural forms, such as shells and arches that are predominantly designed by their structural requirements. However, the typical design process starts with the design by the...

Additive Manufacturing (AM), commonly known as 3D printing, exemplifies the recently emerging processing methodologies that aim to substitute the conventional routes, such as to produce parts with complex geometries and eliminate expensive tooling. AM also allows high degree of freedom and rapid prototyping for functional part optimization. This...

This PhD project explored how the use of 3D printing can support design in a circular economy. 3D printing is an emerging technology and is viewed as a promising production process for the circular economy because of its unique additive and digital character. The aim of design in a circular economy is to preserve the value of products and...

During a vitrectomy procedure vitreous is removed from the eye with a vitreous cutter, called a vitrectome. This instrument is comprised of two needles that move to cut the vitreous into small pieces before aspirating them. Vitreous cutters are complex instruments that are light and small in size to increase their accuracy. Because of their...

The heat fluxes in (liquid) rocket engines can go up to high values and they need active cooling to prevent the chamber wall from failing. Transpiration cooling is identified as a way to achieve lower wall temperatures than commonly used regenerative cooling and regenerative cooling with additional film cooling (referred to as film cooling from...

To create a more sustainable future for aviation, new, lighter-weight structures and materials will need to be engineered. It will also be critical that damage tolerance and safety are not compromised in the process. Lattice materials represents one avenue of exploration; however, two key challenges arise: limited experimental work has been...

Glass is a material which can be seen as a double-edged sword. Its monolithic, smooth, and transparent look transmits a sense of elegance and simplicity. However, due to its brittle mechanical property, it can create complex engineering challenges when intended for a structural load-bearing application. Many forget glass has a comparable...

The preservation and restoration of intricate stucco ornaments, which are part of our collect cultural Heritage, is under threat due to a diminishing number of skilled restoration plasterers. The highly physically demanding- and labour intensive nature of this work makes it unsustainable for the human body and advocates for a more sustainable...
