Formnext 2019: 3D-printed Security Key wins First Prize in Purmundus Challenge

With his project "Stealth Key" Dr. Alejandro Ojeda from UrbanAlps AG won the first prize of this year's purmundus challenge at the Formnext 2019 in Frankfurt. Using Stealth Technology, Ojeda has created a physical key and cylinder system in which the code is neatly hidden under robust, narrow projections. As the key cannot be scanned, it offers maximum security and works independently of digital systems. 

Nicole Hone from the Victoria University of Wellington was awarded second prize for her 4D-printed "Hydrophytes". The hydrophytes are a series of five futuristic aquatic plants and show an innovative approach to organic movement design using multimaterial 4D printing. With the added dimension of time in 4D printing, the designer's role extends to choreographing the performance of objects.

Third place went to Dr. Paul Schüler and Andreas Krüger from CellCore GmbH for their monolithic combustion chamber of a rocket engine. The core element of the demonstration piece is the functionally optimized lattice structure integrated into the chamber wall, which in addition to the necessary stability also offers cooling possibilities through efficient execution.


The audience award, which was voted for by the visitors of Formnext, went to the 3D printed mountain bike frame by Byron Blakey-Milner from NMU ECO-CAR.

The award presented for the first time for Simulation Driven Design went to Gabriel Boutin from KUPOL INC. for his individualized motorcycle helmet KUPOL R1-0. Andreas Henneberg from Diehl Aviation Laupheim GmbH was also honoured with the "Special Mention". He received this for the 3D printed aircraft interior component "Curtain Comfort Header".

With modern 3D printing, Andrea Toulouse from the University of Stuttgart was also able to cross the boundaries of endoscopic printing and win the "Innovation Prize". In this way, lens systems’ can be printed directly on glass fibers and achieve the endoscope diameter in the micrometer range - comparable to a human hair.

All awards were presented yesterday at the Formnext award ceremony.
