Polar printers all follow the same rules, giving them all the same pros and cons:
Pros:
Well suited for a scanner, which they take advantage of.
Large print volume for very small x-axis travel.
Smooth printing of circular objects.
Cons:
Non-constant speed and resolution between the middle of the plate and the edge.
More complex math for the firmware to run to convert the Cartesian-based g-code to polar coordinates. (or a custom slicer that generates polar-based g-code)
Lines passing very near the center require very fast movement of the plate to make a smooth, constant line. (lines actually going through the center cannot keep a constant speed and must pause while the table turns.)

It's a polar printer, but it still prints from the top and not on the side, correct?

Well it would reduce the overhang problem.

Well, it would if gravity were what causes overhang failures... But it isn't.
What gravity does do is it takes the unstuck extrusion from an overhang failure (or any other failure) away from the hot end, rather than allowing it to build up on the tip and insulate it until something catches fire.

Blacksmith seems to be doing well in their Indiegogo campaign, with their early bird specials @$1200 sold out.
It comes with a camera for remote monitoring? Interesting if you can hook it up to a remote controlled wall socket and switch it off remotely when it's done.

Yes, they spammed links for it 4 times in 4 separate threads yesterday.. I think we ALL know about it now It does look interesting, but I will never trust something that is on a repeated 5 second Gif animation, show me a good print session from start to at least the first 20-30 layers.
New to 3d printing looking for...
