This is 3D printing... Lego Technic style. I'll elaborate on my work soon, but here are some pictures of my setup for you to enjoy while I'm writing..
Here's the printer when I was working on the electronics end of things.
It made me cry to do this to do this to a Lego piece (let alone MY Lego pieces!).. At least it was for science!
The z-axis without an extruder.
Testing the motions of the XY bed with some classic RC!
Worm gears made fine control possible and eliminated backdrive.
STAY TUNED! More details and pictures will be coming soon!
