Designed for the TierTime UP BOX 3D printer, the UP BOX Extruder V4 enables the 1.75mm filament to be fed vertically to reduce resistance.
The UP BOX Extruder V4 uses dual fans for cooling effect. You can adjust the airflow from the top fan to cool PLA prints better or avoid direct airflow on ABS prints to prevent warping. The UP BOX Extruder V4 uses an 8mm brass nozzle. This extruder works for all the UP BOX printers.
