The Printrbot Jr. (v2) 3D printer comes fully assembled, has an open platform, a frame constructed of machined aluminum and laser-cut birch wood, and fabricates objects using ABS or PLA thermoplastic filament with a vertical resolution of 100 microns (0.10 mm).

It comes with a direct drive extruder with a cooling fan, and an Ubis hot end that accepts 1.75mm ABS or PLA filament.

The printer is commanded through the provided micro USB cable using G-code numerical control instructions. An SD memory card slot can store G-Code instructions on a memory card for operation without a connection to a computer. It can be used with 3D printer management software packages.

The frame is made of laser-cut birch wood, and folds up for portability. The build platform heats to help provide thermal stability. Machined aluminum axis rods with linear bearings and injection molded gears help ensure precise movement. The size 17 stepper motors meet the National Electrical Manufacturers Association (NEMA) standard ICS 16-2001.
