Polyurethane makes 3D printed orthopedic insoles strong and flexible at the same time

Orthopedic insoles are individualized soles that help people enjoy more comfort. They are often made by hand from a foam that is less breathable than a printed structure. Addigy® offers different solutions to print fully customized insoles from a digital foot scan in an automated process. The result is an affordable and made-to-measure insole that almost eliminates waste in the production process while having a lower carbon footprint. Equally importantly, the insole offers the mechanical strength to support lots of walking while at the same time being soft and comfortable.
“The field of 3D printing offers totally new perspectives for entire industries. Orthopedic insoles are just one fascinating example of what is and will be possible when it comes to more sustainable mass production.”
