What did you do last Saturday? We kicked off the first of it’s kind, 3D Design and Prototyping challenge for motorcyclists, enthusiasts and pretty much anyone who can sketch their motorcycle ideas on paper. BuildTak–a 3D printer build platform manufacturer and SFmototype Sponsor–made these beautiful custom 3D printing surfaces for our Type A Machines Series 1 Pros and Printrbot Simple Metals that are on display at SF Moto (275 8th Street, San Francisco, 10a-6pm) Last Saturday, September 10th, we had the official kickoff of our first ever SFmototype Design and Prototyping challenge–where for 45 days, err, 40 days now–people have the opportunity to sketch out on paper, napkin, envelope, whatever…a concept related to motorcycles and submit it to our SFmototype competition. If their concept considered to be the best by a panel of expert judges, they can win a number of prizes: A motorcycle 3D printers CAD training Shop Training and much much more… We had an amazing set of panelists
It all started back in June 2016 with a “hey, what if we did this…” Now, we’re giving away motorcycles, 3D printers, CAD software licenses and more to those who enter to win and participate in what we’re calling “SF Mototype”. Why? Because we believe everyone has untapped creativity that can be unleashed through Computer Aided Design (CAD) and 3D printing. On September 10th, we’ll kickoff this all-new retail experience where for 45 days, anyone can become their own motorcycle part / component creator. Yes…anyone. At the end of these 45 days, panels of experts will evaluate each submission and prizes* will be awarded to concepts, designs and fabrications which really engender the spirit of this event: anyone should be able to create and build their own motorcycle parts and components…a.k.a. mototypes. You3Dit and SF Moto have teamed up with a number of industry collaborators to enable people to Make Anything, Anywhere (see partners / sponsors below). HERE’S HOW THE PROCESS WORKS: 1. You have an idea
So as we often explain the myriad possibilities of 3D printers for an uncountable number of potential applications, we reel in our audience’s minds by grounding our expectations with “well, I’m not about ready to 3D print my car axle…but there are tons of applications…” While I didn’t 3D print my axle just quite yet, we did 3D print some rim spacer clips in order to eliminate slop between the brake disc and the rim’s decorative center piece.
Why was this even a problem? No one looks cool driving a car that has wacky noises coming from the vehicle. Vehicle sounds are a big part of the driving experience (ask Tesla motors) and while no one should define themselves by the car they drive, no sense in letting it be when the You3Dit network has design and 3D printing resources to easily resolve the issue.
The workflow was pretty simple:
- A thin ring that would fit between the wheel hub and the decorative piece
- Measure the critical dimensions of the wheel
- Transform the sketch into a CAD model (a process called solid modeling)
- Export design to STL
- Slice and drive 3D printer using Repetier
- Test spacer ring on vehicle
- Modify dimensions as necessary
Once we iterated 2-3x, we had a part that worked. The first two were too thick. We made the ring into a “U” shape to allow for slop in wheel dimensions, increasing the likelihood that the part would solve the problem.
If you yourself have the same problem with a pesky aftermarket rim, or you’d like to use this file for any other purpose, we’ve uploaded our SolidWorks and STL parts to Thingiverse.com. The rims featured in this video were purchased from Pepboys are 1097 Proline Wheels.
UPDATE (May 30, 2015):
So the rims and tires handled just perfectly for the last year with the 3D printed rim spacers as designed…and as expected. However, it wasn’t until the service guy rotated the tires when they fell out and the wheels were re-assembled without the spacers. Houston…we have a problem? Or do we? Not really, because the wife of the old man who owns the truck has a 3D Printer–A Printrbot Simple Metal!
So with the help of this article (and Thingiverse’s kind gesture of hosting the files), she was able to re-download the STL and 3D print another set.
So, just when you thought these 3D printing machines were just for younger kids great with computers, think again (note: the woman who did 3D print these is pretty amazing and is pretty darn resourceful for someone of her generation…especially with respect to technology).
