The finalists for the 2020 3D printingpurmundus challengehave been revealed.
Trademarked under rapid prototyping companyCirp GmbH, the eighth iteration of the annual design competition, of which 3D Printing Industry returns as a proud supporter, will feature a total of 35 finalists from 13 countries and 5 continents. Each of the designs showcases a “harmony between geometry and materials”, with concepts centered around medicine, 4D printing, robotics, kinematics, aerospace, sporting goods, and even food.
Geometry and materials in harmony
This year’s finalists deliver a wide variety of 3D printing ideas wrapped up in abstract product design packages. Some notable submissions include the 3D printed Jellyfish Barstool developed by design firmVIADESCON. The seat has a wide base seamlessly connected to an upper structure with one-piece struts. Focusing on sustainability, the filament used to fabricate the structure is a recycled ocean polymer – HDPE.
Medical device manufacturerHKK Bionicswill also be present with its ‘exomotion hand one’, a bionic orthosis for paralyzed hands. The device is described as a motorized glove, allowing its users to perform everyday gripping actions. The whole thing operates on a software algorithm and a sensitive sensor integrated into the PA12 3D printed splint. The sensor is able to recognize the user’s intentions based on the muscle movements further up the arm, thus controlling the microdrives present in each of the fingers.
Acoustics specialistNode Audio Researchwill also be among the finalists with its novel speaker, featuring an SLS 3D printed cabinet. Dubbed the HYLIXA, the speaker features an entirely unified, single-part interior cabinet geometry, complete with a patented helical pathway and a rear woofer. The rotational pressure of the helix is designed to increase its effective line length, enhancing the speaker’s bass capabilities.
Next up, we have the Legendary Salmon, a 3D printed plant-based sushi developed byLegendary Vish. Designed to emulate the look and feel of the real thing, the dual-extruded fillet can be produced with a 95% reduction in greenhouse gases and up to 90% less energy consumption.
Metal 3D printing firmMX3Dwill also be presenting its topologically optimized robotic arm, which was designed by simulation-driven design companyAltair. Produced in stainless steel using MX3D’s WAAM 3D printing process, the arm features weight savings of over 50% and can be completed in only 3 days. The company intends to use the arm on a production robot manufactured byABB, which specializes in industrial automated robotics systems.
The winners of the 2019 purmundus challenge
Last year’s challenge saw38 finalists head to the Formnext trade showin Frankfurt to compete.First place was taken by the 3D printedStealth KeyfromUrban Alps, followed by the 4D printed ‘Hydrophytes’ developed by Nicole Hone of theVictoria University of Wellington. Third place was taken by the monolithic rocket engine combustion chamber created by Dr. Paul Schüler and Andreas Krüger ofCellCore.
The winners of the 2020 purmundus challenge will be presented with their awards on 11 November at the virtualFormnext Connectevent, complete with a live digital awards ceremony. The panel will make their selections based on economy, use, aesthetics, and of course the innovation of the design itself. In addition to the general top three places, there will also be an award for a ‘Special Mention’, ‘Simulation-Driven Design’, an ‘Innovation Prize’, a ‘Newcomer Prize’, and even a poll-determined ‘People’s Choice’ award.
As well as a share of 30,000 Euros, the winners will also be presented with the prestigious purmundus challenge trophy.
