I clicked the link and searched for the UV light and bought it.

 Thanks, Mark, Have one on the way.


  I still don't have any shipping info from "3D Printer Bay" yet.



 I'm not that proficient at drawing in sketchup 2017 pro yet, so I'm looking at DIY 3D scanners. Let's say want a "379 Pete" in N scale and have one in HO, I would like to be able to scan the HO version and then scale it to N, and then print it. I'm hoping that with a scanner, it will save a lot of time not having to draw it up. Once scanned, I will be able to take it into a CAD program and fix anything that the scanner missed and/or add details that the original didn't have.

From what I have been reading on the Interwebs, it will likely take you longer time to clean up the 3D scan (so it is usable) than it would be to draw it from scratch.  Also what is the resolution of today's 3D scanners?  H0 truck is quite small.  I suspect that you expect too much from today's computer technology, but I hope that I'm wrong.

If you want t sharing an H0 model, you would likely get much better results Hydro-shrinking the H0 model and casting the N scale version in urethane resin, like @Rasputen does.  Or wait until Trainworx makes one - they have dune Peterbilts already.

Cool Rodney.  I know there's a lot of tools available for turning scans into 3D models.  And that's a perfect segue into the next test.

Bare with me, this one gets a little weird.   


One of the things I always wanted to try was 3D printing N Scale figures.  3D Body scan tools are becoming increasingly available, but without any such service here yet, I'd have to manually sculpt figures, which is a LOT more complicated and time consuming than building ridged models, so I never got around to it.

Now that I have my own printer, I want to push the limits and see what it can do.  And, well, since we happened to stumble upon a 3D body scan a few posts back....   
Let's just say I do these things so you don't have to. 

I scaled Naomi's 172mm mini down to 6% for N scale using Anycubic's software.  For this one I also set the layer height to 20 microns.

I've gone this far.  No turning back, let's get some paint on it. 
Looks like grandma is searching for a handkerchief, or anything, to help this poor girl cover up.

Ok, let's have it.  Hit me with your best snark. 

Did I miss an opportunity to paint the bikini Conrail Blue?

Wow!
Nice legs too!

[Mark W]

Wow!
Nice legs too!

I know, right!  (Speaking purely in regard to the print quality.. of course..    )

[rodsup9000]

 I'm still impressed with the quality. And you right, it's the legs.

You found your niche, Mark.

I was using the "Pete" as a example. I know that Jason (@superturbine) used the hydro-shrinking for the boilers he was casting.

 If I can build one that has .05 mm resolution, it will be something to play with.  Then I can decide if it's worth trying to use for printing.

Mark, that is one of the first n-scale people I have seen whose proportions seem natural. Well done! And great legs.

I had a really hard time watching Naomi’s video, but that was the lab director in me cringing at the bare skin with chemicals around.  Lab coats can be just as sexy as bare skin....

And for everybody getting one of these, please do yourself a favor and get some good quality eye protection, too. For all the steps involved.

[Chris333]

Are you going to add LEDs?

Of course!

If you are capable of building such a scanner, then I'll be anxiously awaiting your results.

Like 2D printing, you're going to need a scan resolution at least double your print resolution to get even a decent result. Something around 10-20 microns in this case.

Yes they can.  I sure miss Mythbusters. 

And definitely agree on eye protection.  The included spatula for removing parts from the plate is flimsy and downright useless.  Splatters resin everywhere.

I found using a razor blade is by far the easiest way to remove prints, though comes with it's own level of caution.   



Rodney, you mention this as an example, but N Scale Addict @HuskerN already has a 379 Peterbilt model.  Seem's he's vanished the past couple years though.  I wonder what he's up to now days.
