The rider, who lost the lower part of her leg in an accident when she was two, is promoting the new method of making a sports prosthesis, which advocates say is quicker and cheaper to produce, without the lengthy process of plaster-casting.
Schindler - who is collaborating with U.S. company Autodesk that designs the software behind the 3D printing - demonstrated the project to U.S. president Barack Obama and German Chancellor Angela Merkel at an industry fair in Germany a week ago.
"We are currently testing the 3D-printed prosthesis and whether its quality reaches that of the traditional handmade prosthesis," she told Reuters.
"It feels different," she added, while putting one on.
Schindler, who won a silver medal at the 2012 Games in London, is due to compete in the Paralympic Games in Rio which run from Sept. 7 to Sept. 18.
