Linssen, Jonathan (author)A broad range of bistable, multi-stable and neutrally stable compliant mechanisms have been developed over the years. These non-monostable systems show great potential for deployment in e.g. the medical, the manufacturing and the precision industry. Often the presence of prestress is a requirement for obtaining non-monostability within the realm...master thesis 2022

Kaymenaki, Vassia (author)The main objective of the current study is the investigation of the behavior of structural joints consisting of Shape Memory Polymers. Taking into account the large environmental impact caused by the massive production of structural materials, the change of the current structural design philosophy is becoming essential. Conventional structural...master thesis 2018

Pakvis, Sara (author)In recent developments in the field of multi-material additive manufacturing, differences in material properties are exploited to create printed shape memory structures, which are referred to as 4D-printed structures. New printing techniques allow for the introduction of prestresses in the specimen during manufacturing. This research focuses on...master thesis 2021

Holierhoek, Jesse (author)The aim of this project was to get a better understanding of the shape memory behaviour of 3D-printed polymers, and the different parameters which affect this, with the ultimate goal to apply shape memory in product design. This project started with a literature study on shape memory polymers and 3D-printing. The material properties, different...master thesis 2021

Dijkstra, Bas (author)This research investigates the challenges a user faces in the activation step in shape-changing products. First, previous research on the topic of 4DP is reviewed and important factors are described. Namely, activation temperature, print temperature, print speed, and layer height have a signifi cant impact on the shrinkage...master thesis 2024
