I have an Asiga Max. If you are wanting to print your C&B (which is what I do. I print all of our wax-ups),I would hands-down go with an Asiga. I wouldn't trust a Form2. They're just not as accurate and efficient (Hence the price gap). I think they're decent for printing models, but they don't even advertise them for printing C&B (at least, that was the case back in March). The Max was specifically engineered for commercial use, and dental labs in particular. With our Asiga Max, I never have any issues whatsoever. No failed prints, no hiccups. The resin is inexpensive, and you can use resin from third parties as well. If you'd feel like talking about the Max, send me a message and I'll give you my number. I highly recommend you stay away from the Form2 for your C&B. You're going to have a lot of headaches. And Envisiontech? Who's that? I can't possibly recommend Asiga enough, and I'm not a salesperson. I just love their product.
As for technical specs, the Form2 is an SLA laser, and the Asiga is DLP. Basically, the Form2 has a UV laser that has to hit every single point on a layer individually. Whereas the Max uses a digital UV projector, which prints the entire layer at once. This results in more accurate and much faster prints.
