MakerBot Smart Extruder, Replicator Mini

The modular, swappable Smart Extruder minimizes downtime and prepares you to quickly adapt to future innovations in the fast-evolving world of 3D printing. Replacing a worn extruder with a backup couldn’t be easier and you don’t need any special tools. Powerful magnets snap it into place in seconds, letting you quickly resume printing when a replacement is needed. This swap-ability also allows you to adapt your 3D printer to future innovations (like new filament materials) without having to purchase a new printer.
