21 Oct 2013 UPDATE: Shorter extension tracks added. Instead of 130mm long, they're 120mm long to fit UP Mini.

Been working on this for a few weeks now, trying to build an easily assembled desktop 3D scanning kit to go with IntriCAD Triangle software... The idea was to create a casing that not only houses the turntable and the circuit boards that go with it, but also provides a base that has slots for the extension tracks. Originally a large base board about 600mm x 600m was required for fixing everything in place at the right angle and distance, but the board took so much space on the desk that I found it unpractical.

Now with this kit, I can slide the laser and camera back and forth along the extension tracks to adjust the distance, or up and down their own bases to get the right height. They also sit at the angle of either 30 or 45 degree from the laser. I added a piece of curved locator in the end to hold the extension tracks in place because the long it gets, the harder it is to have the camera fixed at the correct angle.

Still in the process of perfecting Dual Camera mode... I couldn't find many tutorials online that explain how to make the cameras work together, but I'm still getting some good scans.


The entire kit was designed based on IntriCAD Triangle scanning requirements.

1 x laser
1 x small turntable
1 or 2 x HD webcam(s)

The assembling of the kit should be quite straight forward once you have all the parts printed.

Ah someone else who wishes to scan their teeth! I too want to get the unlimited retainer hack for real life so I got a mold of my teeth from the ortho... Could you post the resulting model of your teeth scan to show how well it works?

what control board are you using

Hi,can you tell US how you drive thé stepper motor?

what type of stepper motor are you using? And how are you controlling the stepper?


What software do you used to scan?


do you think that a stepper motor will do the trick for the turntable?

Yes the kit I have here does have a stepper motor.

This comment has been deleted.

But i would need some kind of motor in the turn table right? and if so, is it made for mounting a motor?

Thanks in advance

Hi, the housing is for the stepper motor. There's a locator going under the motor to hold it in place.

Anyone have links to the camera and laser? And do you plug this into the computer?

I bought the cameras from local computer/appliance shops - Logitech HD Pro Webcam C920 (USB connection to your computer). The laser you can easily buy from eBay, which should be powered by a battery pack. Hope this helps.

The laser holder's cylinder is partially on the other side of the bar that goes into the base. That kind of makes it really hard to print. Any chacne you can rerender the part without that extra bit to the cylinder?

Does anyone have a BOM list for this scanner? It looks awesome and I want to build me one, but kind of need to know what hardware to buy first, and also calculate what the total building cost might be.

I'm printing base tomorrow I plan on using 1/4inch wood chisel and file to clean up I'll post pic if it works

Anyone have issues printing the turn table base? all the holes get filled up for me with support and its impossible to remove it without damage. Using slic3r 1.0.0rc2

Can't you just use one camera with TriAngles?

Wouldn't doing that cut costs and complexity?

Yes you can just use one camera. The only reason I've allowed for 2 cameras in the design was because the software had the option to do so, hence trying to accommodate both situation. I was told that to make the dual camera mode work, the lines have to line up perfectly to get good scan. :)

Or, if you can wait a couple of weeks, and are willing to make or adapt a 2-cell battery box for it, you can get one from Ebay.
I just bought one from them, (won the auction), for $3.95, free shipping, from China. http://www.ebay.com/itm/660nm-5mw-Focusable-Red-Laser-Line-Module-1-pcs-/261313055986?pt=LH_DefaultDomain_0&hash=item3cd778ccf2http://www.ebay.com/itm/660nm-...
Of course it's safer to get the factory part. I just got this one as a spare, along with one that projects a cross. ($5.75).

You're making it more DIY than I did! Great job! Are you using Triangles software as well? If so, I was told that with the dual camera mode you have to align the lines perfectly to get good scan results.

The complete kit, including the turntable, comes from the previously printed link;http://store.3dprintingsystems.com/3D_Scanning/3D_Scanner_Kithttp://store.3dprintingsystems.... I just ordered
a second Logitech camera from Ebay, for about $70.00. These are very good cameras.
I don't know where to get the laser, but it should be easy to find. The turntable needs
a stepper-motor with driver, (pololu?) I think it is. You have to print your own mounting
parts for the aforementioned scanner kit, and idea_bean's are a lot better, IMO.

This looks AWESOME! One quick question, and I apologize if you did cover this and I just missed it, but what did you use for the turn table?

Hey this is a really amazing idea that I'd love to construct however I'm on a relatively tight budget. After poking around, I was unsuccessful in finding proper lasers or cameras to make this work. Could someone refer me to a place where I can buy these parts? The sources below were for very expensive kits that didn't have great explanation of the parts they included. Thanks

What service! The new bars are printing, as I write this! All this completed in one day's time. What a splendid happening. I will
assemble the scanner & send some pictures, tomorrow.

Thank you for your very kind offer. If you could shorten the track segments to 5 inches, (127mm), I would be very grateful, as it would allow me to complete your version of the scanner much sooner. I'll be happy to share what ever I can come up with.

Hi, the ones I uploaded previously were 130mm long. I have reduced their length to 120mm and uploaded a new STL file. Hope that makes things easier for you. Thanks.

Thanks for the comment! Hopefully you can get some better scans using this setup. I can always shorten the tracks to fit UP Mini if you like. Please do share some photos of your scanner setup and scans when you have time. Cheers :)

I was able to make all the parts for this, except for the tracks, on my UP3D Mini. I'm still trying to get my Mendelmax running, so I can print larger things. This is a splendid design! I just wish the guys at 3dprintingsystems were as good at making instructional movies
and user's manuals as you are at redesigning their crummy parts! Thank you for doing this for us! (I still have not gotten a decent scan
with their scanner. I only get unusable garbage out).

There's a list of components required for the setup on that page, so it should give you an idea what to get. I designed the base plate to fit the turntable I got from them tho. If you're getting different kind of turntable, you'll need to tweak the design a bit to fit. Thanks

Hi, you can buy the software and components from here - 3D Printing Systems. http://store.3dprintingsystems.com/3D_Scanning/3D_Scanner_Kithttp://store.3dprintingsystems...

Any chance for a BOM of this kit? I'm thinking this is something I'd love to build and experiment with! Awesome job!

this is awesome! i vote for it to be featured
