I don't own an ultimaker, but do own
2 UP Plus 2's
QU-BD Revolution XL
So you could say that I know a little about 3D Printers. Up until I received the Zortrax, the UP Plus 2 were the benchmark in high quality printing with good support and rafts that were easy to remove. This changed when I received my Zortrax printer which produces superb prints with very good support and rafts. I am extremely impressed with the build quality and components used in the printer and for the money, I think it is probably the best printer on the market at present.
The firmware and software is still beta so the printing can only get better from here out.
