Does the Da Vinci line of 3D printers come with a heated bed? I'm now currently looking at getting my next 3D printer, after my success with the Prusa i3 Reprap Build, and I have had my eyes on the Da Vinci line of printers for some time now. 

What I want to know is, does this line of 3D printers include a heated bed? Or does it come with a stock aluminum bed?
Yes. The Da Vinci Duo 2 (most common one) has a heated bed.
