The Ultimaker 2 is one of our favorite 3D printers on the market. It’s a well-built open-source compact machine with an excellent UX. Every inch of the Ultimaker 2 is designed to create the most effortless and reliable 3D printing experience ever!
The ingenious print head silently and precisely maps out your creation to an accuracy of 20 microns. That means that print lines are barely perceivable creating a really smooth finish. And with its heated print bed and highly efficient dual fans, the Ultimaker 2 even takes overhangs and bridging in its stride.

Is it really set up for 1.75mm filament? According to the Ultimaker web site, they spec it for 3 mm (2.85mm) filament.
Hi, not out of the box
the linked forum on the product page (https://ultimaker.com/en/community/view/6739-175mm-filament-on-ultimaker-2?page=1) has the settings for the software and ptfe tube needed to work with 1.75mm. The tube is available here: http://www.geeetech.com/budaschnozzle-20-ptfe-tube-for-1753mm-filament-p-787.html
and then change the diameter size in cura or any slicing software.
