Moorhuhn bicycle takes first prize in Purmundus Challenge awards

Stay up to date with everything that is happening in the wonderful world of AM via our LinkedIn community.

The Moorhuhn bicycle frame design took first prize at the eighth Purmundus 3D and 4D printing design awards, that were presented at the digital Formnext Connect exhibition. In total, seven submissions won awards on this year’s theme, geometry and material in harmony, but all thirty-five finalists will present their designs at the virtual Formnext exhibition.

Dennis Lang, Head of Communications & PR for the purmundus challenge, highlighted the importance of this challenge: “In a challenging year like 2020, the relevance of 3D and 4D printing has been highlighted again. The AM community is pulling together, and managing to add value for society in addition to breaking new ground in the field of design.”

The Public Choice award remains to be announced. Public voting for the award closed on November 22, 2020.

1st prize: the Moorhuhn bicycle frame, HUHN cycles | Ralf Holleis

The Moorhuhn combines the advantages of super light Titanium tubes and connects them with additive manufactured Lugs, this makes the joints extremely stiff as they can be designed according to the forces within a bicycle frame, and distributes them equally.

2nd prize: exomotion’s hand one, HKK Bionics GmbH | Dominik Hepp Moorhuhn bicycle takes first prize in Purmundus Challenge

The exomotion hand one from HKK Bionics is an innovative bionics hand orthosis for paralyzed hands. Designed as a “motorized glove”, it enables patients to carry out every day gripping tasks.

3rd prize: ZERO – 3D printed sneakers, Svet Abjo I Zellerfeld Shoe Company Inc.

Special Mention: Tactile Compass for colours, Taktilesdesign GmbH | Sylvia Goldbach I Eric BahrMoorhuhn bicycle takes first prize in Purmundus Challenge

The Tactile Colour Compass leads into a new world of perception. It guides its users through landscapes, pictures and everyday objects through touch, which provides blind users with the ability to use a compass.

Innovation Prize: ANAMOS heart model, ANAMOS UG (haftungsbeschränkt) | FAPS – Lehrstuhl für Fertigungsautomatisierung und Produktionssystematik, FAU Erlangen-Nürnberg I Wacker Chemie AG I Hannah Riedle I Anna Seufert

With its realistic function and feel, the anatomical model of a human heart, which is produced using additive methods, opens up new opportunities for the simulation of surgery.

Simulation Driven Design: Bolt it, ETH Zürich | Inspire AG I Gressel | Julian Ferchow I Marcel Schlüssel

The BOLT-IT concepts enable an automated physical and digital post-process chain. BOLT-IT are universal interfaces, produced within the additive manufacturing process. They enable automated gripping and handling of the AM part.

Newcomer Prize: Adaptive splint, School of Design Innovation, Victoria University of Wellington | Yejun Fu

The Newcomer Prize was awarded for the first time in cooperation with Addmio. This category distinguishes students, start-ups and newcomers. The winner will design the Newcomer Prize 2021 trophy with Addmio’s support.

This project explored the possibility of engaging 4D printing in building wearable devices, exemplified by an adaptive wrist splint for progressive rehabilitation. This included researching wound healing processes and related rehabilitation methods to determine the required functionality of the splint and exploring relevant biological structures as inspiration for the design geometry.
