3D Modeling and Parts Fabrication

No problem.

Maybe he can design and 3D print me up an airless rear tire made of nickel titanium shape memory alloy overlayed with a hard rubber center strip and softer rubber edges. I'd even take a round one. LOL.

This posting gave me some nice flashbacks of my University days preparing to be a CADD/CAE professional, robotics engineer or 3D animator (life took me down a different but rewarding path though)...

It took me awhile to find this 'glory days' mini-me photo used in the colleges 1989 Engineering Studies advertising booklet.


Catia was a million dollar software program running on a very expensive IBM mainframe system. You can create things 100x better on a laptop now.

Its showing a 3D model I created of the USS Nassau Helicopter Carrier I was stationed on with a few choppers landing on the deck as it rolled through the seas.

I actually did that for fun as I had already gotten an 'A" on my senior project.

For that I had created a model of the entire campus and filmed a video fly-over landing at the Computer building entrance then walking into the computer room and up to a simulation of myself creating the campus model. Sadly, I don't know where that tape ended up.

That looks like a good model, but I don't have a Roadster to compare it to... does the gas tank on that model seem a little squared-off? Does the bike look like the real one? I did see this one earlier, and I think it has the best front fender emblem of all the ones I've seen, but if the actual geometry of the parts isn't accurate I'm not sure how useful it'll be.
 

I'm sure it is not 100% accurate but looks close enough for a starting point. You would have to dig deeper to see how fine the scanning resolution was.
It's also possible that the rendered 3D images shown do not show all the detail contained in the actual model files.

These sites have both a 2013 R3R and R3T and appear more photo-realistic but they didn't have the file formats for your software (maybe they can be converted??):

Triumph Rocket III Touring 2013 3D Model - FlatPyramid

They also have 3D files for Triumph logos and emblems (hmmm).

Yup and it would do some really weird things to the IO controllers to avoid channel timeouts. Thew wuz the days when you could almost feel the data jiggle down the big fat copper cables. Men wuz men!.
 

I saw these earlier, the part that concerns me for these touring models is that it seems they've been modeled from a picture that the guy was looking at, because the rear brake master cylinder (or at least the cover) is non-existent. I would expect it to be there if it were a scan that had been cleaned up. Also they just copied the handlebar controls from the right side to the left side, which doesn't give me much confidence in the modeling logic.

I wonder if there's anywhere that the parts of the bike are drawn in 2d that's reliable.
 

My company has pretty cool rapid prototyping workshop, couple of Fortus 3D printers, Datron milling machine, recently we are waiting on new Hexagon arm with RS6 scanner. 3D scan of Rocket should be doable, but if you want to have the output somehow practically usable for production of parts or accessories, you have to scan each bike part one by one, than compare with the oem part.. But that is a HUUUGE job to do.
 

It sounds like you have quite the workshop, I'm a little envious. Where are you located and what bike are you able to scan?

With regard to scanning each part in detail, I agree, and have little intention of scanning any parts that I do not have to to generate whatever custom pieces we need/want. I would think that a general scan of the exterior of the bike(s) would cover a lot of the trim pieces, but as far as mechanical parts requiring close tolerances go, I'm not entirely sure that I'm able to manufacture reliable parts anyway.
 
I have 5 bikes myself and if I ask all my friends.. there would be a lot of 3D scanning The workshop is about 300 miles from where my bikes are, plus the weather is prohibiting so nothing will really happen until late April. But I can check if someone from my team wants to entertain what are the possibilities, once the arm arrives. I usually do not bother them with anything bigger than clamp, mount or attachment, which is about 1 hour job at the PC plus some 3D printing to verify fitment.
