It's a pretty neat device. I haven't seen any others that operate like the Formlabs device does (starting with a pool of liquid and hardening the desired part out of it). Is that a new development, or has the technique been around for a while?

I was looking at buying a 3d printer within the week. I am price sensitive. I have budgeted 600$ (no higher).

Will this device come within my budget?

If Formlabs lives up the to hype and is only $600 I'll be very impressed.

Might as well wait and see though, unless you're in a rush.
