Wow. 3D scanning combined with 3D printing on things like the MakerBot Thing O'Matic and others is going to change the landscape of DIY!

totally the direction I am going. My budget allows for the TOM during the first quarter 2012. I can not wait!!!

Thank you very much :-)

Awesome project great for creating 3D models for games ect..

A little more tinkering and I bet it will work perfectly.

Keep it up.

Thank you, I hope to have the last upgrades by august. Then it should be operating to my expectations.

Congrats! Cool project. What type of laser is that?

Is it a special laser for 3d scanning?

Do you think servos would do the job?

A servo may work, IDK. A servo would likely perform well on the platform, as it only rotates in 90deg increments.

With a stepper I can control how fast it moves, which was important for the laser. With the EasyDriver (sparkfun.com) I can move the stepper in micro staps, and write a little more delay beyond that.

The Laser is just a cheap Ebay line laser. At this stage I just wanted to put the pieces together and see if they work right. The design alone went through many revisions as they software changed the requirements.

Speed, Camera, and Laser all contribute to the resolution of the scanned image. The laser I have now is too thick, and the speed is still a little fast (even though the video shows it at 2x speed).

I found a resource at anaheimautomation.com. They sell a stepper with a gear reduction box which will give me a slower pass.

I also found a resource in the states for a better laser. David LaserScanner sells laser, but doesn't appear to ship to the states.


Laserglow has a 2.5mm adjustable laser I hope will provide the resolution I want (especially at 209$!)
