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...

Background: Wrist immobilization orthosis is a commonly adopted treatment method for wrist regarding pathologies. In recent years, a group of 3D-printed immobilization orthosis for the upper extremity has been proposed. However, they were mainly developed as substitutes for traditional casts for the upper extremity for short-term usage. There...

The human eye is a very delicate yet highly intricate organ, and treatments such as cataract surgery call for meticulous precision. Ophthalmologists hone their skills over years of practice, which they initially acquired during their studies in medical schools. Basic skills such as globe fixation and capsulorhexis training have a very steep...

Throughout history, human progress has been defined by the mastery of materials, transitioning from stone and bronze to the steel age. However, this progression has not only been defined by the materials utilized but has also encompassed a shift in processes, moving from the industrial to the information era. Despite the advances in fabrication...

Overtoom, Jelle (author)
A relatively new and not rather common technique in construction industry is the use of 3D printers to print architectural structures and buildings. Nowadays, parts of the printed object are build in inside environments, where after the parts have to be transported to their desired location, which is very costly and time consuming. A solution...

Bieling, Thijs (author)
Evaporation can induce acoustic emissions in microfluidic devices. The origin of these emissions and their damping remains elusive. This thesis studies acoustic emissions from 3D printed microfluidic tubes mimicking xylem vessels in plants. We show the time and frequency domain signature of these emissions. From these signatures, we identify...

Wong, Jasmine (author)
The construction industry and the existing building stock are significant contributors to greenhouse gas emissions. To address this environmental challenge, there is a growing interest in using bio-based materials, such as wood, in architecture. Yet, the availability of wood resources is limited.<br/>Bamboo, a non-wood species, holds promise as...

Bierach, Christopher (author)
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...

Steerable medical instruments are used to reach difficult locations in the body during minimally invasive surgery (MIS). Researching these instruments helps to further improve their performance and reduce their size making them even less invasive. However, developing new technology can be expensive and often complete custom test rigs are build...

Multi-Material Additive Manufacturing (MMAM) is an emerging manufacturing approach that is gaining interest in architecture and construction as an expansion of Additive Manufacturing. Hereby, different materials or material properties are combined in a single additive process in order to create objects that are composed of multiple materials....

Fabrication of complex and multi-articulated mechanisms is often seen as a time consuming and demanding process. The development of functional multi-articulated mechanisms that could be fabricated in a single step without the need for post-manufacturing assembly is therefore very attractive. Additive manufacturing (AM) has been pointed out as...

The existing 3D printing methods exhibit certain fabrication-dependent limitations for printing curved constructs that are relevant for many tissues. Four-dimensional (4D) printing is an emerging technology that is expected to revolutionize the field of tissue engineering and regenerative medicine (TERM). 4D printing is based on 3D printing,...

Additive Manufacturing (AM) or 3D printing has enabled the production of increasingly complex parts that are difficult to produce with conventional manufacturing methods. Its additive nature has made it possible to create interlocking parts in a single production step. This creates opportunities for new ways of designing and producing...

Heavily resource-reliant transportation and harsh living conditions, where humans cannot survive without a proper habitat, have prevented humans from establishing colonies on the Moon and Mars. Due to the absence of an atmosphere, potential habitats on the Moon or Mars require thick and strong structures that can withstand artificially...

Cities are the core of social interactions and resource consumption in our current times. However, urban systems are still largely based on linear activities in which resources are discarded after usage. Current practices around waste reduce possibilities of circularity, mainly due to low percentages of sorting and recycling practices in high...
