This is great tech. I fear its going to be far from PLA-printers price wise, for a while at least ;)

Re: Carbon3D – 3D Printing via Continuous Liquid Interface Production
#12The site is so cool that it just screams "fake". Cool pictures, not much copy, no details. The big difference here is that they're doing photopolymerization at the bottom of the tank, rather than at the top like everybody else. This requires a transparent material that passes oxygen on the bottom of the tank, so the action takes place on the surface of that membrane. They're vague about the details. How long does the…
Re: Carbon3D – 3D Printing via Continuous Liquid Interface Production
#13I still think the biggest thing stopping adoption is most people not having any idea what to print on a 3D printer, even if buying, operating, calibrating and maintaining one was cheap and easy.

That should let them print really quickly and precisely, even compared to the SLA printers you link.
The reason it hasn't been possible in the past is that the polymerization process requires oxygen, which has only previously been available from the air over the liquid resin. Their system has some "secret sauce" for getting it to the bottom of the vat.
Re: Carbon3D – 3D Printing via Continuous Liquid Interface Production
#18speed seems to be a factor - i think SLA printers are limited by resin curing time under UV light.
perhaps this is more a resin technology than a printer technology.
they do keep mentioning oxygen - but it's not clear why

They've raised 40m from Sequoia, so it's reasonable to conclude there's been some degree of vetting. Given that they show video of a working prototype it's very likely this vetting included independent observation of their printer in action. Their product might be useless for some other reason, but if so it's non-obvious enough for them to have raised a non-trivial amount of money.
