van Oudheusden, A.A. (author), Buijserd, A.J. (author), Doubrovski, E.L. (author), Flipsen, Bas (author), Faludi, Jeremy (author), Balkenende, R. (author)Spare parts availability is crucial for extending the life of consumer products. However, long-term availability could lead to high stocks of spare parts, which might not be used. Instead, on-demand manufacturing of spare parts with additive manufacturing (AM) is a promising alternative. This paper presents a method to evaluate parts on their...conference paper 2023

Hedayati, R. (author), Stulova, Victoria (author)Due to payload weight limitations and human vulnerability to harsh space conditions, it is preferable that the potential landing location for humans has an already constructed habitat preferably made from in situ materials. Therefore, the prospect of utilizing a readily available Martian material, such as regolith, in an easily programmable...journal article 2023

Hedayati, R. (author), Stulova, Victoria (author)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...review 2023

Bolanos Arriola, J. (author), van Oudheusden, A.A. (author), Flipsen, Bas (author), Faludi, Jeremy (author)This guide takes the reader through the 3D Printing for Repair (3DP4R) process. It consists of guidelines and tools to create a 3D printable version of spare parts needed for a product repair. 3D printing a spare part is more than just printing the original part. Instead, it is an iterative process in which the part is analysed, redesigned,...book 2022

van Helvoort, Derron (author)Additive manufacturing allows material structuring, supporting the fabrication of multiple-level structures or metamaterials. Through the lens of classical stress reduction, nature’s cellular solid structures feature stress-homogenizing nodal topologies. Avian long bones are an example. Research into the mechanics of open cell cellular solids...master thesis 2019

Zhao, Song Chuan (author), Maas, Mariska (author), Jansen, K.M.B. (author), van Hecke, Martin (author)Additive manufacturing strives to combine any combination of materials into 3D functional structures and devices, ultimately opening up the possibility of 3D printed machines. It remains difficult to actuate such devices, thus limiting the scope of 3D printed machines to passive devices or necessitating the incorporation of external actuators...journal article 2019

ten Cate, W.J.A. (author)This graduation project was started on the observation that most orthopaedic companies seem to be still far away from producing 3D printed sockets for customers. Research into manual and digital manufacturing methods resulted in an overview of the possibilities for integrating digital tools into the socket production process. Together with the...master thesis 2017

Bots, M.J. (author)Cellular solids are characteristically excellent energy absorbers due to their capacity to store large amounts of energy through compression. A bioinspired design approach identified the Pomelo fruit (Citrus Maximus) as a biological role model for energy absorption. Fruit peels’ biologically most important functions lies in the need to provide...master thesis 2017
