The Delft Pro Simulator: An accessible and 3D-printable prosthesis simulator to simulate transradial limb absence

<b>Introduction: Prosthesis simulators are essential tools for research and rehabilitation. They can be used to increase the amount of participants in research studies or to assist in rehabilitation. The main goal of this master thesis is to design a functioning prosthesis simulator, which can be used with commonly used...

Design of non-assembly mechanisms: A state-of-the-art review

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...

Steel 3D printing for structures: An explorative study on the tear-out strength of a pin or bolt in a Wire and Arc Additively Manufactured carbon steel plate

Additive manufacturing (AM), or 3D printing, is emerging as a technology for different applications made of steel. It is expected that in the coming years the construction industry will benefit from the free and lightweight forms that can be fabricated and the possible material savings. A few experimental results of 3D printed stainless steel...

A Comparison Between Representative 3D Faces Based on Bi- and Multi-variate and Shape Based Analysis

In Ergonomic product design, designers need to translate anthropometric data of the target population into product dimensions or sizing systems. Currently, sizing systems are often based on traditional anthropometric data and generally use the variation of one or two key body dimensions directly related to the product. For products that need to...

Application of 3D printing in Repair

Repair was once a common act. With increased product diversity and complexity, a scarcity and obsolescence of spare parts is making repair increasingly difficult and economically unviable. The result is an accelerated turnover of manufactured goods, which are more often replaced than repaired. As products are discarded, embedded materials and...

Design of a 3D printed prosthetic socket that accommodates pediatric growth

Inability to adapt to growth is a problem in the field of pediatric prostheses. Current prostheses do not adapt to the normal growth of children’s limbs and require constant visits to health care providers for adjustment or replacement. To solve this issue a new socket was designed making use of auxetic metamaterials. The residual limb of the...
