A (Mostly) 3-D Printed Race Car Hits 140 Km/h

An anonymous reader writes with an excerpt from a story describing the efforts of a 16-person team called "Group T" competing in the Formula Student 2012 challenge. They've created a car called the "Areion," described as the world's first 3D printed race car. "The Areion is not wholly 3D printed but most of it actually is. It was tested on Hockenheim race circuit and went from zero to 100km/h in just four seconds. Maximum speed Areion achieved on the same circuit was 141km/h." The car features an electric drive train and bio-composite materials, and was created using a printing system called Materialise.

    In honor of it being a slashdot car story, instead of providing the official slashdot car analogy, I'll provide the slashdot computer analogy to the story.

    "Its like 3-d printing a computer case, and then having the media report the entire computer was printed, circuit boards and all".

    Its just the exterior of the car that was printed, not the motor or the wheels or whatever. This is not to belittle the accomplishment... for 3-d printing that's a very large component to print, and also the stereotype of 3-d printed stuff being weak seems to be finally going away....

      Except the circuit board is a major functional component of a computer. What was printed was more like the decorative bezel on the front of the case... all the weight and stress bearing components being of more conventional manufacture.

      You may not realize it, but racers aren't street cars - racers have frames that carry all the weight/stress.thrust and roll cages that protect the driver. The shell is pretty much decorative.

      It's not a monocoque... this bodywork is just bolted onto a steel spaceframe. It's made from a polymer resin, so in some respects you could say 3D printing has caught up making things out of plastic, but there's not a great deal of load on these panels to stress it.

  7. The short wheelbase looks funny by Bartles · · Score: 2

    Anyone know why this design decision was made? Is it because the area in front of the console is the only place tall enough to place shocks and springs, while still having room for the drivers legs?

    1. Re:The short wheelbase looks funny by Brianwa · · Score: 3, Informative

      It's because Formula Student courses are extremely tight and curvy. A shorter wheelbase gives you a smaller rotational inertia, which means you can enter and exit corners faster. This comes at the expense of high speed stability, and indeed most FSAE/FSC cars get quite unstable above 90mph.

      On top of that, a shorter car is a lighter car, and every gram counts on a race car.

    I know this is a silly question, but what exactly is it that these so-called Slashdot "editors" actually do? Given the never ending inaccurate summaries, the summaries with all the grammatical elegance of grade-school assignment, the summaries that are essentially just the first paragraph of the story, the summaries that reference rip-off web blogs designed for noting more than soaking up page views while that actual source is some other web site entirely...

      Editors? Where have you read that we have edit ... wait, damn!

      Sorry, that was a mistake. We meant to say this site is run by redditors. We hired an entire team of them. We couldn't get slashcode to actually autosubmit the stories, since our coders are lazy, so we needed some cheap labor to do it. The cheapest we could find was redditors. So essentially we pay them a (very small) salary to go on reddit all day long, taking small breaks to log into /.'s admin panel and randomly approve stories. We are currently teaching very basic english to a group of illegal Mexicans. As soon as they are at the level of our current editors (that is, speaking a grand total of 25 words), we'll replace them, and you'll immediately see a noticeable improvement in the quality of our stories.

      So, redditors, sorry for the inconvenience. We just asked our redditors to correct the mistake in our FAQ and change editors to redditors, but they flipped us the bird and went back to /r/gonewild. You'll just have to wait until we get our mexicans ready.

    Yeah, I'd argue most of the car wasn't 3-D printed at all, since they didn't print the engine, drive train, or tires. Whether or not the seat was printed is left up in the air.

    The fact that it's a tiny race car isn't particularly relevant - it's the size of the print job that's interesting. But really, it's no more impressive than if they'd 3-D printed a dining room table.

    The title and summary are misleading to the point of fraud. Here is a (not comprehensive) list of things that they didn't print:

    The frame (welded tubular steel, just like every other car in the competition)
    The wheels and tires
    The suspension, linkages, and steering
    The batteries
    The electric motor
    The cooling system
    The electronics and controls
    The driver

    What they did use 3D printing for was for the body panels, and probably some complex-shaped internal parts they didn't bother to highlight. But Formula teams have been using 3D-printing for various components (yes, even body panels) for upwards of a decade. Hats off to the team itself - nice car! And a nice big "give me a fucking break" to the submitter, editors, and Materialise PR.
