Check out the Makerslide Delta Robot 3D printer on Thingiverse. My Google/ROS friend Damon has been begging me to do this for a while. Looks like I waited too long.
I have being pondering with the idea of a Delta printer (especially with MakerSlide) for a while now. With a little searching I found some others out there.
This one isn't MakerSlide, but it’s pretty cool. It’s also built using a CNC router. http://www.joshendy.net/
I am starting to pool some ideas and see what I can come up with. I don’t currently have access to a 3d printer, so all the parts I fab will have to be made on a lathe or my ShapeOko.
