Atlas 3D Kickstarted Laser Scanner Now Available

Post by twforeman » Tue Oct 20, 2015 1:09 pm

I tried searching the forum for this because I was pretty sure it had been discussed before, but I couldn't find it.

Anyway. The Atlas 3D Laser Scanner is now available for purchase. I discovered the Kickstarter campaign about two days after it ended and have been waiting impatiently ever since for it to go up for sale.

I ordered one yesterday and it shipped right away. Guess I need to start printing up the parts!

This should help quite a bit with some of the parts duplication that I've been doing.

Looks interesting. Although the hardware design doesn't seem to be open source, they seem to be using FreeLSS for the software side. FreeLSS is Open Source, being developed on GitHub:

It was mentioned in this thread:
http://www.shapeoko.com/forum/viewtopic ... las#p40490

I happen to have the scanner already...
(Kit. Printed the frame myself)
It's a bit of a pain getting it dialled in correctly, and it also works very, very poorly with anything metallic.
I will suggest getting hold of light-absorbing flocking or fabric if you get it.
(Mine still require adjustments. I just haven't had the need to get it working properly, yet)

The STLs should be available somewhere, and the rest was promised, also.

Incidentally, Uriah Liggett, who is behind the FreeLSS is also the man behind the Atlas.

I don't know why these are so hard to find, but here's the link. http://www.murobo.com/printables.html

If you decide to get it, the acrylic parts kit may be a good idea unless you have a GOOD 3D printer. Some of the parts can be rather finnicky if the print is only slightly off.
And spring for the Pi 2 B+.

Thanks for the heads up twforeman, I also missed the kickstarter and have been waiting for this..

Gadgetman, what are the issues with metallic objects? Is it just shiny reflective surfaces that are an issue, or metal in general?

I use a 3D scanner as a part of my day job. Shiny objects and even flat black objects sometimes throw it for a loop. To get past this (as all of the parts we want to scan are metal) we spray the part with a developer used for dye penetrant testing of welds. It sprays on clear and turns a chalky white as it dries. It has a chalky texture and rubs/wipes/washes off pretty much as easily as something covered in chalk. I can't attest to how it works with plastics (as I haven't tried) but it seems pretty harmless and temporary.

I just grabbed the can of developer we use and it's "Ardrox 9D1B Developer". Looks like a spray paint can and Google says it cost about $10. That being said, I imagine there are plenty of different brands out there that'll work and many metal supply or welding supply places should have them in stock if you give them a call.

I think any spray that gives a matte surface should work.
Even a can of matte black spray.
Just remember to consider the 'washability' of the spray, what the object can withstand and whether or not it matters if the finish changes...

I've gotten hold of some 'light absorbant' black flocked sheets I'm going to use as a backdrop, and to cover the turntable with.
(Yet another of my endless list of projects)

I'd recommend against a flat black spray. We have a white light scanner (so it uses a series of white/black bars to sort out the contours of the surface) and flat black tends to absorb too much light for us and caused some issues with accurate scans. A flat white spray consistently produced better results than flat black for our particular scanning setup.

Also worth noting, the developer I noted earlier wipes off with a dry rag easily (and rubs off your on your fingertips every time you touch it) or washes off with water. It's a whole lot less hassle than anything else we've found thus far.
