Los ganadores de este año son:
1er premio: new pointe shoe sole
act'ble GmbH I Sophia Lindner
Developement of a tool, that’s made to move. Moveable in itself due to the geometry. Enabling perfection of aesthetic movements
As a young and dynamic innovation team we re-think one of the most iconic, aesthetic, and powerful sports: ballet. act‘ble is a young company creating a new art of movement. Design and Research together with high level athletes leads to the developement of a new pointe shoe for classical ballet and contemporary, that lasts 5 times longer than conventional pointe shoes and dramatically reduces physical pain. We want to enable dancers to make a difference in their performance, live and world. Through our patented concept of a 3D printed Sole combined with an upper we create new possibilities of movement and individual artistic expression.
State of the art
Pointe shoes are made by the most elaborate handwork. In over 100 steps a shoe is made from several layers of linen and glue, which is then oven-hardened for 24 hours. The durability of a pair of shoes is 1 day in professional sports, which puts the dancer at extreme health risk. The Royal Opera House in London, for example, invests 250,000 EUR in pointe shoes alone per season.
Thanks to 3D scans, 3D printing and functional knitting, we develop a performance she that fits perfectly
To eliminate the conflict between the necessary flexibility and stability, the sole has cuts at the bottom. They allow free movement for the upward and downward rolling movements of the foot, where physiological walking is not possible with conventional shoes. On the other hand, for standing on the toes, the optimal support function is ensured by the segments closing and blocking. According to a modular system, the sole and the upper shoe can be exchanged later.
In 3D printing we have found a tool that offers the same precision and individuality as the athletes themselves. Mass personalisation and motion capture also open up possibilities that were previously unheard of in this industry. In over a hundred iterations, we 3D printed an individually generated prototype every 1 to 2 days, further optimised it and tested it with high-level athletes from the surrounding state theatres and companies with extremely positive feedback. Due to the high precision of the FDM process, we were able to develop a performance sole in rapid prototyping that never existed before. The 200-year-old traditional pointe shoe is completely rethought.
Fluent transition from prototype to series product
The next step is to optimise the sole geometry for the SLA process in order to produce 3D printed soles that will also be sold directly to customers.
Scenario ”Beta-Testathlete”: Permanent optimisation through direct customer feedback
The first 3D printed act’ble shoes will be available for purchase in early 2022 as part of a beta study. For high-level athletes, there will be the possibility to make adjustments to individual needs in terms of performance and health. Thanks to mass customisation, dancers will be able to find a tailor-made answer to their individual requirements. It is no longer necessary to test/ consume a large number of shoes in order to find one that comes close to fitting. 3D printing + form-knitting offer the basis to produce without waste.
Our vision is based on one of the greatest cultural assets that has always shaped humanity: Dance. In addition to the world’s leading Stuttgart State Ballet, we would like to set another milestone in the region and further develop this cultural treasure and make it available to dancers worldwide. Quote from our survey of a dancer from the New York City Ballet: “I hope dancers will take more ownership of their career and its prevention and will behave more like high-level athletes.
The product development takes place in close cooperation with dance medicinists and the TA.MED e.V. (Tanzmedizinischer e.v. Deutschland). From a health perspective, muscular training processes in particular can be significantly optimised through the new sole. A topic that is long overdue in ballet. Together with the Fraunhofer Institute IPA, a research series in the field of mass personalisation and motion analytics will be aimed. The aim is also to build the sole geometry parametrically in the future based on a generative design based on the dynamic forces. The focus of further development is on stress optimisation. For this purpose, a tool is to be used to optimise current predetermined breaking points in the future through stress analyses / topology optimisation and to identify stress peaks.

3er premio: HEXR, the world's first custom fit cycle helmet
HEXR I Jamie Cook I Henry Neilson I Theo Clarkes I Mark Brown I Jess Lewis I George Jary
HEXR, the custom fit cycle helmet. Our unique design uses a honeycomb structure to offer market-leading head protection while ensuring maximum comfort.
The creation of the helmet starts with a fitting-scan of the head, which is quickly measured by the our guided app using a cloud of points and the custom fitting HEXR is automatically generated on the server.
HEXR places great emphasis on social impact and sustainability - the PA11-based material consists of 100% castor oil. It is sustainably sourced by Arkema through the Pragati initiative, which supports sustainable farming methods, reduced water consumption and fair working conditions. The inner honeycomb structures and the smaller helmet components are 3D printed. The finishing touches include the assembly outer shell, chin straps, padding and an optional 3D printed ratchet system. The helmet is not only custom made, but additionally personalised with the customers own engraving to truly give the helmet that personal touch. HEXR is one of the first products to make it to mass production on the market through hybrid manufacturing using Advanced Technologies. The helmet also provides groundbreaking safety standards without compromising fit or aesthetics.

Innovation Prize: Bespoke 3D Printed Soft Robots
Bio-inspired Robotics and Design Laboratory - Singapore University of Technology and Design I Washington State University I University of Colorado Denver I Pablo Valdivia y Alvarado I Narasimha Boddeti I Tien Van Truong I Vincent S. Joseph I Thileepan Stalin I Theo Calais I Shien Yang Lee I Martin L. Dunn
Material properties and composite structures play key roles in tailoring the performance of 3D printed functional devices such as Soft Robots. Unfortunately, current design (i.e. traditional CAD) and fabrication approaches limit achievable complexity and functionality in these two categories and hinder the performance of 3D printed functional devices or products.
This project takes a systems level approach that allows innovative design and direct fabrication of novel soft composite structures. The process uses computational topology optimization to determine the required 3D composite structure of soft hyper-elastic bodies.
As an example application, the figures on the right show the design of a Soft Batoid-like robot (TOP) and the design of the optimal 3D composite structure for fins that enable high propulsive performance (BOTTOM).
The direct fabrication of the soft composite structures using an all-in-one fabrication workflow with resilient silicone polymers enables precise tailoring of mechanical properties. By applying this approach to the design and fabrication of an underwater batoid-inspired soft robot, significant swimming performance improvements are demonstrated. The pictures below show the fin fabrication process via Direct-Ink-Writting (DIW) and embedded 3D printing (LEFT & CENTER) and a detail of the fine features of the 3D composite structure of the fin (RIGHT).
The design and fabrication approaches developed for this project complement each other in a novel way to provide a higher degree of customization and functionality in silicone based 3D printed functional devices. Our computational design approach enables optimization of the material property distribution to yield desired body kinematics at a new level of complexity. The required material distributions are translated into equivalent soft composite structures and the resulting tailored robot kinematics enable performance not achievable using traditional fabrication approaches.
An optimized composite prototype (images BELOW) displays 50% faster swimming speeds, 28% faster turning rates, and 55% smaller turning radii than un-optimized benchmark prototypes.

Newcomer Prize: Highly Functional Integrated 3D Printed Brake Caliper
ETH Zürich - Product Development Group Zurich I Aschraf Danun I Michael Wehrli I Remo Elmiger I Ole Müller I Tiago Ogris I Tom Felder I Prof. Mirko Meboldt
As part of a student project of the Product Development Group at ETH Zürich, we designed a highly integrated bike brake caliper for metallic additive manufacturing to demonstrate the free functional complexity potential of AM with three added values: design freedom for internal fluid channels, the functional integration of both, a monolithic compliant membrane and topology optimized lightweight design. Traditional brake calipers are hydraulically actuated using pistons. They consist of two halves that are held together by screws. Unfortunately, the design is prone to leaking. Also, the assembly and bleeding are time-consuming. We managed to reduce the number of parts from eleven to one by replacing the pistons with a compliant mechanism: a thin corrugated membrane. This monolithic design allows the caliper to be printed as one single part with all functionalities integrated. The fluid channels were optimized to trap less air while bleeding. The design is scalable and could be applied to cars or aerospace as well. The -35% lightweight design is visioned to reduce fuel consumption and CO2 emissions in such an application domain.
