3D Scanning

I searched the forum for scanning and found most topics were related to medical issues...a bit too early for me but I'm interested in 3D scanning parts and making them reproducible.
I am a complete newb (that means I haven't done it a lot 9-) but have made some progress. I wondered if there was an interest. I started with an exhaust collar -it was not an easy part to start with but I got it scanned and meshed and was finally able to print a part - including the voids in my original. Now don't get all excited about 3d Print exhaust collar it's not up to the task but there are ways...
I'm going to try a Tomaselli lever next, it looks like it has been ground down and needs some clean up .
I'll scan parts I don't have to remove from the bikes, maybe something useful will emergeIMG_1991.jpeg

Rearset plates and switchblocks immediately come to mind 🤔
 
If you want a Laverda part to print, make the choke lever. The last one I bough was $175 and was told it was the last one he had. They started out as aluminum which don't break and by the 70's were plastic and I have broken three of them.

When printing aluminium how strong is the final product?

I am aware of two types of printable aluminum - one is effectively 6061 so I expect full $strength. I've received a quote once before and it was not consumer ready There is also SS that can be printed.

I have a friend with a bunch of parts - I'll ask to see if he has one. As mentioned I'll not be taking my bikes apart.

Very nice!

Which software/hardware are you using for scanning?

Is it possible to share your files, the very first scan and part shown? WHICH ONE? the Exhaust Ring?

I have an Einscan Rigil and use a variety of SW to clean up scans - I haven't been doing it long enough to settle on an ideal workflow but start with EXScan and EXModel, use some Meshmixer and do additional work in Fusion
I generally don't mind sharing files but it's not all going to be free.

I commissioned a lot of 3d/rapid manufacture back in the 2010s. Even then one of the suppliers was using data to laser sinter parts of Subaru WRC gearbox internals

The big boys can afford to do that. My last quote was for about $8000 for a part that could be machined for a couple hundred 9-)

I have no experience with 3D scanning, but i am very interested in technical terms.
However, regarding some simple tasks like recreating a choke lever, it seems to me, remodelling is another cheap way to go.
But having the right equipment on hand: open end!
 
There are some things, probably most, that modeling is much easier to use. However there are things scanning does that make modeling easier. An airbox is a good example, it can be modeled but if you had a reference it would reduce all those trips to the shop with calipers. And if you scanned a motorcycle…Here is a three minute test scan

Porsche apparently uses quite a few 3D printed parts in their hybrid drive trains. Watched a docu on the Porsche assembly line recently, it was stated the gear/differential casings are printed! Printing is especially interesting for low-volume applications where casting/machining would be horrendously difficult and expensive, pushing unit prices into regions nobody wants to accept. Prints generally require a minimum of machining to finish off and not much is wasted in the form of swarf.

Printed bits all over high-tech applications, try googling Bugatti Veyron brake caliper, mind boggling. Lots of titanium printed bits in aviation landing gear.

Pretty amazing what can be achieved with plastics alone, I do think they've got the metallic strength issue covered...

I found this printer as a kickstarter project. aluminium and other metals are needing complicated sinter procedures as I understand, and this printer can used already for some parts like the choke lever etc. with some limits though. and progress went on in the background.
 
 
I find this 3D printing stuff interesting, but, my print capabilities amounts to me cutting a potato in half, cutting in a design, dipping it in paint and printing it out on paper, then I scan it to see how it worked out.

Whereas with 3D, it seems you scan it first???
