I Greatly Appreciate the range of filaments that can be used in the printer, and also the Fantastic upgrades from the Ultimaker Store And '3D Solex'-(the reason why I chose the UM3 E, over Raise 3D), this allows for Quite Useful machine add-ons like the Ruby and sapphire Nozzles of various sizes, which in turn allow prolonged printing of course (professional) filaments such as Nylon X (Carbon fiber) filament & Layceramic filament...
I Do However dislike the WiFi and NFC technology integrated into the machine because of adverse health effects that result from long term electromagnetic pollution exposure resultant of these radio frequency and microwave frequency emissions, however that can be fixed by placing aluminium foil between you and the printer.
I would have also appreciated a larger build plate (eg. 400 mm X 400 mm X 500 mm) but that would lower total revenue, so the new machine roughly $10,000 AUD called the 'Ultimaker S5' partially makes up for this aspect, the money spent on the camera NFC, and or WiFi should have been put into a dry-box so that the pva filament and other hygroscopic filaments would be protected and therefore usable.
All-round Smooth machine.
