Formnext Connect: 3D-printed Moorhuhn Bike wins first prize of the Purmundus Challenge

35 finalists stood a chance of winning the purmundus challenge trophy. As a reminder for this 2020 edition of the Purmundus Challenge, participants competed under the motto “Geometry and Material in Harmony”.

On October 9th and November 1st, we unveiled a few creations that sparked the most our interest across the sport, fashion, art and food industries. Looks like the winner was Ralf Holleis for its 3D printed Moorhuhn Bike.

The Moorhuhn Bike, boasts an optimized bicycle frame geometry courtesy of additive manufacturing. The Moorhuhn frame is made from ultra-lightweight titanium tubes, connected by 3D-printed lugs. This makes the joints extremely rigid and distributes the forces evenly.

HKK Bionics is similarly venturing into new areas of application with the Exomotion Hand One: The bionic hand orthosis, which takes the form of a ‘motorized glove’ has been developed as a functional, reliable assistive device for everyday life to restore the gripping function of paralyzed hands. Intelligent software connected to a sensitive sensor integrated within the biocompatible PA12 3D printed splint recognizes the user’s intentions based on the muscle movements further up the arm and controls the microdrives in each of the fingers.

The 3D-printed Sneaker Zero by Svet Abjo is a fully functional, recyclable sneaker that is made to measure on the basis of foot scans.

This year, the purmundus challenge also announced a new award: Yejun Fu from the School of Design Innovation, Victoria University of Wellington, received the first ever Newcomer award for the Adaptive Splint. The project investigates the use of 4D printing for an adjustable wrist splint for example. Other winners included the ANAMOS heart model (Innovation Prize), the tactile color compass that generates haptic experiences for people with sight loss (Special Mention), and the BOLT-IT concept, which enables an automated physical and digital post-process chain through automated gripping and handling of the AM part for post-processing (Simulation Driven Design).

The audience prize remains open for votes until 22 November 2020. The winners of the purmundus challenge will each receive a share of a €30,000 prize fund.
