0%?? It's not quite there yet and rather deceptive, IMHO. It can do some of the receiver from 0% stock, but you still have to purchase the "lower-lower" premilled section and either purchase the tower section (all 3 parts required) or... you can CNC one but requires other specialized tools (additional $200 kit) to actually complete it.
80% receivers are, for the moment, still allowed. I doubt it will be long before they go after those too, though.
That certainly puts machines like the GG3 on the radar, though. Especially since it's not limited to only doing AR style receivers, but it seems the affordable desktop style CNC's are still a ways off from being a practical solution. Just the raw materials and required parts for 1 receiver will run you $110 + shipping and that's not even factoring in the machine itself... for a highly proprietary receiver.... dependent on a proprietary source for proprietary parts necessary for completion.
The easy and affordable solution... stock cheap 80% deep enough to hold over the next generation or two.
Affordable desktop 3D printers and true 0% CNC's capable of producing MFG quality frames and receivers are both an eventuality, IMHO.
