Qualification of 3D configurator for customized prosthetic hands
In this project, you have the opportunity to help us further develop a 3D configurator for the customization of prosthetic hands. The project involves developing an automated workflow to simulate design variants using FEM and identify critical designs for part qualification and testing.
Keywords: customized prosthetic hands, design automation, FEM simulation, rhino/grasshopper, part qualification
With the rise of additive manufacturing, also termed 3D printing, it is now possible to fabricate novel products that are customized for the specific needs of a customer. 3D printing allows offering individualized products for different consumer and medical applications. The team of SwissProsthetics (https://www.swissprosthetics.com/) at Wyss Zurich develops customized 3d printed functional and affordable prostheses. A modular system of prostheses allows to easily perform many different activities. These range from the use of a touch screen, to household activities and most importantly, sports. To enable the fast and easy customization of prostheses, the team has developed a 3D configurator that allows generating customized designs for 3D printing.

To enable the fast and easy customization of prostheses, the team has developed a 3D configurator that allows generating customized designs for 3D printing.
The task is to implement methods that ensure the qualification of the generated designs of prostheses. Once a variant is generated from the 3D configurator, the idea is to automatically perform a structural analysis using FEM simulation. For the qualification of the configurator, this allows to screen the design space of possible prostheses designs and identify critical variants that need to be tested. The work packages are:
1) Research state-of-the art methods for qualification of part variants generated from a product configurator
2) Get familiar with 3D-CAD tool Rhino/Grasshopper
3) Program procedure to perform FEM analysis in Rhino/Grasshopper (using an existing plugin or through external FEM tool)
4)Automatically generate and FEM simulate a large number of prostheses designs
5)Analyze results using multi-linear regression modeling
6)Documentation of results with recommendations on qualification and testing of variants
