Meet Dave of Sculptify!

Interesting printer.  I watched the videos on their site and I must say, it's pretty nifty.  It also validates my concept of using ball screws for the X/Y motion.

There are a couple of things to consider though.

The printbed doesn't appear to be heated, so I'm not sure how that will work for ABS and other plastics like it that want a heated bed.

There's no mention on whether or not you can add coloring dies to the hopper to color the plastic.  As is, you only have choices for black, white, gray and natural.  If I were them, that would be the first thing I would offer as an option, not a grinder. 

I would think that you could use any blender/food processor to grind the waste plastic into something the printer can reuse, so I don't see any sense in spending money on a dedicated grinding machine.

I didn't see any mention of cost.  Any ideas?

Among other questions, the one that sticks out is the fact that none of their parts have complex geometries or retractions.

As for cost, I'd bet $2k+. These guys aren't cobbling it together in their garage out of laser cut wood.
