The Printrbot Go Large Fully Assembled 3D fused-filament-fabrication printer with triple extruders is designed for portability and has an open platform for fabricating parts up to 24 x 12 x 12 inches (H x W x D) using three 1.75-mm ABS or PLA filaments (sold separately). The printer has a wood frame that folds into a compact, portable box with handle for transport or storage. Collapsing the frame for transport does not require dismantling any parts, and the hard shell protects all internal components. The triple extruder enables printing in three colors or materials, including water-soluble PLA for temporary support structures in a printed part. The printer head moves on the X (left to right) axis and Z (up and down) axes, while the bed moves on the Y (backward and forward). The printer uses open source software and connects to the computer using the included micro-USB cable. The integrated Raspberry Pi single-board computer allows computers, tablets, and capable phones to connect remotely to the printer over Wi-Fi and control the print job. The printer accepts a battery (sold separately) for use when a power outlet is not available.
The print table is machined-flat MIC 6 aluminum cast plate and includes an auto-leveling probe that works with the user-chosen computer software to provide a level print surface. The guide rails have a 12-mm diameter for stability and dual NEMA 17 motors with linear bearings for smooth vertical movement of the print head. The GT2 belt and aluminum pulley system facilitates precise movement of the print head. The hot end has a maximum resolution of 100 microns and includes a shrouded fan to help solidify the molten material by directing air toward it as it is extruded onto the print table. The printer includes two sample lengths of PLA (polylactic acid) filament.

Fused filament fabrication printers build prototypes and parts directly from computer-aided-design (CAD) data sources by stacking layers upon layers of molten material. The print material is provided in filament or wire form and is fed through an extruder within the print head, similar to how ink is used in a standard printer. A printer with a single extruder can print using one filament at a time; a printer with dual extruders can print with two different materials or colors at the same time. The thickness of the printed layers can be customized for each print, but the thinnest layer that a printer can lay is called its maximum resolution. Choosing to print using very thin layers will create parts with more detail, but will typically take longer to print. To lay the material in the correct way, the print head and bed typically move in a combination of X-axis (left and right), Y-axis (forward and backward), and Z-axis (up and down) movement.
