Optimiertes Bauteil »MG Bracket rear« (Demonstrator)

Now in its ninth year, the popular award was presented at Rapid.Tech to students working with additive manufacturing processes who have taken advantage of the resultant opportunities for product customisation within the context of rapid manufacturing processes.
We collaborate with design experts, specialists from within the sector and renowned companies to produce a selection of high-quality submissions. This prize represents a unique opportunity to generate interest within the industry and make important contacts. 
All three winners are students from the member institutes of the Fraunhofer Additive Manufacturing Alliance - a network of 13 Fraunhofer institutes who carry out research in the field of additive manufacturing. The young scientists were able to convince the international jury with their design concepts for optimum energy use.

 

First Place: »Cooling with Heat« - a concept for efficient heat dissipation, Jonas Deitschun, Melanie Gralow, Lena Heemann, Sebastian Kalka Daniel Knoop (Fraunhofer IFAM, Bremen)

First place, with a prize of 2,000 euros, went to the team led by Jonas Deitschun, University of Bremen. Jonas Deitschun, Melanie Gralow, Lena Heemann, Sebastian Kalka and Daniel Knoop developed a concept entitled "Cooling with Heat", by means of which heat can be dissipated efficiently through the use of functional microstructures. The resultant "heat exchanger" won over the jury with its high level of innovation. The object’s structure and design were adapted to the chosen manufacturing process, meaning, for example, that no supporting structures would be required for manufacture. The jury praised the object’s design for its bionic approach, which borrowed from the natural design principle of a tree with branches subdivided into smaller branches and twigs, as well as leaves.

 

Second Place: »structure-optimised heat exchanger«, Kilian Böll (Fraunhofer IWU, Dresden)

A heat exchanger was also the focal point of the project awarded second place. Kilian Böll from Dresden University of Technology impressed the jury with the design quality of his "structure-optimised heat exchanger" as well as with its aesthetic qualities, which were based on organic structures. The jury lauded the submission’s forward-looking presentation of plans to optimise the component in the future.

 

Third Place: »Topology optimisation for the additive process of electron beam melting«, Michael Süß (Fraunhofer IFAM, Dresden)

Fellow student Michael Süß won third place in the coveted award programme with his concept "Topology optimisation for the additive process of electron beam melting". Here too, the jury commended the high optimisation potential of the component as well as the associated weight savings and resource efficiency. Thanks to its design, the component can be produced without restrictions using the chosen manufacturing process. At the same time as optimising the stability, this also allows for weight optimisation.

 

Rounding off the award ceremony at the Erfurt Theatre, Dutchman Joris Peels, Community Manager for the 3D printing platform YouMagine, presented a critical, satirical, and at the same time forward-looking view of the current 3D printing hype in a talk entitled "3D Printing: Between endless possibility and a pool of infinite suck".
