MakerBot Tough Smart Extruder+

The MakerBot Tough Smart Extruder+ features a 400-micron (0.4mm) nozzle diameter and is designed for the MakerBot Replicator+ 3D printer and the MakerBot Replicator 3D printer (5th Gen). The extruder can be magnetically swapped for easy maintenance and material switching. After you switch, it can detect the filament and even pauses your 3D printing job to warn you when a spool runs out. Active jam prevention protects both your extruder and your prints.
