3D printing company Stratasys has announced the winners of the 2017 Extreme Redesign 3D Print Challenge. The company co-hosted the event with GrabCAD, a digital manufacturing hub that hosts an expansive online collaborative environment for designers, engineers, and manufacturers. Judges selected the victorious candidates from over 900 submissions, coming from student inventors, engineers, artists, and entrepreneurs from all around the world.

Now in its 13th year, the Extreme Redesign 3D Print challenge gives students the opportunity to redesign an existing product, create a new product that will improve a particular task, or design a new work of art or piece of architecture. They must make use of 3D printing technology in their projects and they are evaluated according to specific criteria, such as their creativity, real-world achievability, and mechanical soundness. This year’s panel of judges included Todd Grimm, President of T.A. Grimm and Associates, Manufacturing Engineer Diana Foster, Ryan Erickson of Cedar Park STEM School and Michael Santolupo, Design Teacher at John Paul II Catholic Secondary School, London, Ontario.

According to Gina Scala, the Director of Marketing at Stratasys' Global Education wing: “3D printing has the potential to transform industries—truly revolutionizing how things are made. Our Extreme Redesign Challenge regularly highlights the most significant student innovations achieved with 3D printing, led by the intellect of young minds. This year, we received some of the strongest entries in the contest’s 10-plus year history. These winners truly represent the ‘best of the best’ in student creativity and design.”

First-place winners in each category received $2,500 scholarships, with $1,000 being awarded to runners-up. A demo 3D printer was also given to educators of the winners, for use in classrooms for a limited time. The National Coalition of Advanced Technology Centers (NCATC) winner is also awarded a $1,000 scholarship.

Check out the winners of this year's competition below: 

Engineering (Secondary Education):

First Place went to Grayson Galisky of Los Alamitos High School, CA, for his Biomimetic Robotic Prosthetic Hand. The hand was mostly 3D printed using an Ultimaker 2. Grayson’s innovation was to model the mechanics of the hand after the bio-mechanics of a real human hand, as opposed to conventional robotics techniques. By incorporating elements like 3D printed tendons and ligaments, the prosthetic hand has vastly improved dexterity and performance compared to most robotic prosthetics. It also means that it’s not necessary to write new code for the control of the hand—data can be tracked from the movement of a regular human hand using draw wire sensors. The overall cost of the project came to less than $600, and it took about 2 days in total to print and assemble all the parts.

Engineering (Higher Education)

First Place was awarded to Thomas Salverson of The University of Alabama, NE for his Arm Cast. He designed his cast to be modular, adjustable and reusable, all 3 of which are improved attributes compared to the conventional plaster/fibreglass cast used to heal broken bones.It was 3D printed with a Makerbot Replicator Mini from strong ABS filament. The cast incorporates a modular ring and adjustment pads, so it can be modified as the patient’s bones heal. Salverson’s cast design would be very cost-effective and easy to put together—it could even be done by the patient herself.

Art, Architecture, and Design

First place went to Daniel Fahy for his Intricate Flower Centerpiece. The 3D printed flower is a beautiful ornament, as well as functioning as a candleholder and a jewellery box. It was based on the dahlia and zinnia flowers. The complex CAD design for the flower was 3D printed using an FDM machine and ABS Plus Filament, although Fahy suggests that an SLS or SLA printer would be even better to capture the intricate surface details. A number of different color combinations are possible

NCATC Prize

The winner of the NCATC Prize was Jacob Haynes, of Danville Community College, Virginia. His project was a Universal Tablet Holder for Phantom Drone. 3D printed and held together with nuts, bolts and elastic bands, the tablet holder would allow almost any tablet-sized device to fit firmly onto a drone controller and was made as part of the college’s prospective drone program.
