German college students need to use 3D printing technology
In the past 9 years, the HAWK University of Applied Sciences and Arts in Hildesheim, Germany has held an "Akkuschrauberrennen" or "cordless screwdriver racing" every year. As the name implies, the student team participating in the competition needs to design and manufacture a single-passenger vehicle, and the car can only be driven by an electric screwdriver. So every year there are a lot of creative vehicle designs, and each team is trying to make the fastest and coolest car.
In this year's competition, organizers keep up with the times and require at least a portion of each participating vehicle to be 3D printed . Specifically, each car must be at least 50 cm in 3D printing (the maximum width of each car is 90 cm). In addition, all vehicles must be manufactured in a sustainable manner and exhibit an organic design.
In order to meet the new competition rules, a large number of teams used 3D printing technology to create innovative designs for their cars. For example, the Ostfreezer team at Emden/Leer University of Applied Sciences created the 3D printing portion of their vehicle with the help of 3D printing services company Materialise. Their cordless screwdriver racing car is called Akkuracer and was designed with Materialise Magics and 3-matic modeling software. The software enabled the team to design a complex structure to meet the requirements of organic design. After the design was completed, Materialise used laser sintering technology to print the parts in 3D and transport them to Germany for competition.
The competition was held on June 25th and the audience gathered to watch the eleven cars on the Hildesheim track. Each team can get their own electric screwdriver one minute before the game. Of course, some teams were disappointed to find that their vehicles were in trouble immediately after inserting an electric screwdriver. For example, the MOPET team from HAWK collapsed within a few minutes of the start of the preliminary round, but their vehicles performed better later that day. The impressive Akkuracer racing team of the Ostfreezer team, although not winning any of the top prizes, was happy to enter the quarter-finals themselves.
It is reported that there are many factors to consider in the game evaluation, such as speed, technology, design and overall impression, which are decided by the audience vote. As a result, the audience dismissed the MOPET team's poor record and awarded them the highest prize; the Screwdriver team from Ostfalia University of Applied Sciences won the fastest award.
