Personalized prosthetics with Freeform Injection Molding

”If my prosthesis broke, I’d have to walk to the other side of the table and yield the match. I’d have no alternative,” says Peter Rosenmeier. As World Champion, European Champion, and former Olympic Champion in Paralympic table tennis, he has competed at the highest level for more than a decade.


The handmade prosthesis that Peter Rosenmeier used to hold his racket throughout his career quickly wore out as the 2020 Paralympic games approached. Basing his entire playing style on this unique item, he would potentially lose Paralympic 2020 – and his career – if he didn’t find a proper replacement.


“This was quite an innovative process. As far as I know, this is the first time ever that someone has combined CT-scan, data segmentation, CAD modeling, and injection molding in 3D-printed soluble tooling to deliver a personalized object.” - Daniel Minzari, Specialist Engineer

Together with the Institute of Product Development and the Danish Technical University, he found an elegant solution to this unique challenge: CT-scan the prosthesis to safeguard the physical shape of the prosthesis in a digital format. Then use Freeform Injection Molding to produce the physical object.


The results of the project speak for themselves. At the 2020 Paralympics, Rosenmeier took home the silver medal playing his brand new prosthesis.
