Printrbot is a 3D printer created by Brook Drumm and originally funded through Kickstarter. It is aimed at beginner home users through its small size factor, low cost and ease of assembly (claimed to take 45 minutes).[1][2][3] Printrbot uses fused deposition modelling to produce plastic models of 3D objects. Since creation, the original Printrbot has been discontinued and replaced with newer versions which vary in price, size and functionality.[4] As of April 2012, Printrbot was the most funded technology project on Kickstarter after receiving $830,827 USD in December 2011.[5]

Design and operation[edit]

Printrbot is sold as fully assembled or as a kit requiring assembly.[4] Models are printed by depositing molten ABS or PLA plastic filament onto a hotbed from a print head which moves about the X and Z axes (the Y axis is controlled by the movement of the hotbed itself) using electric motors, guided by metal threaded rods.[7] The models to be printed are sent to the printer via a USB interface using specialized software such as Pronterface (recommended by the manufacturer).[1][6][7]

Assembly[edit]

As of November 2012, current models of the Printrbot are sold as fully assembled or as kits. According to Printrbot's return policy, returns are only accepted if the device "has never been assembled, powered up, programmed or changed in any manner". If repair is needed, many of the components for the printer are available to be purchased separately.[4][8]

Filament[edit]

Current Printrbot models can print in ABS or PLA plastic filament which can be purchased from the official store or other sources.[4] Printrbot models can be outfitted to accept 1.75mm or 3.0mm diameter filament. The filament is available in many colours; the colour of the filament will determine the eventual colour of the model printed from it.
ABS filament is available for purchase here.
PLA filament is available for purchase here.

Software[edit]

The printer is controlled through a USB interface.[1][7] Printrbot does not come with any software and the official getting started guide recommends using the freeware program Pronterface to interface with the printer.[6]
