The Ultimaker 2 is easy and reliable, designed for the best user experience in 3D printing. Featuring a .4mm single-head extruder capable of an amazing 20 micron maximum layer resolution, 12 micron XY precision, and 5 micron Z precision, the Ultimaker 2 is the best consumer 3D printer available today. A 633 in3 build area [9 x 8.8 x 8 in] gives you plenty of space to build what you need, and a maximum print speed of 300mm/s makes sure you don't have to wait a week to build it. A small print-to-size ratio lets the Ultimaker take up a minimal amount of desk space.
