I bought ABS from Frys (made by MG Chemicals?) and it printed with the Monoprice FF rebrand (bed heated to 110C) first time, no problem. Even printed at 100% infill. Used Makerware 2.4.? with a sled.

I was surprised, cause when that part was printed on a different printer with different ABS, it curled significantly. Don't know whether that print used a heated bed.
