Is a heated bed necessary if printing with PLA? I'm looking at getting this printer, the da Vinci 1.0w 3D Printer, very soon as my first printer. Since this is an enclosed printer, from what I can tell from the pictures, and given that it is a PLA Printer (I'm assuming that is the filament it prints with), is a heated bed necessary? Especially since this printer doesn't have one? Or should I look at a ABS printer instead?

I plan on printing 1:1 scale props.
There is problem with sticking to bed without preheat, PLA is possible to print on Kapton tape with no-heated bed. Or there are other tapes dedicated for printing. da Vinci 1.0w is good for small models with PLA. ABS is not possible with no heated bed.
