Artist D and Artist D Pro Assembled Extruder Kit with Quick Replacement Nozzle

Quick Nozzle Replacement: Featuring an Extruder module with an innovative one-button "Nozzle Eject" system, Artist-D, Pro allows you to easily swap nozzles, or quickly replace the nozzle in the event of a clog.  Easy Feeding System: The distance between the filament feed motor and the nozzle is as close as possible. No long Bowden tubes here, which means flexible filaments are much easier to print! And the extruder assembly is enclosed with a cover, keeping you safer from hot extruder parts.Note:  Atist d is not suit for Artist d Pro 3D Printer
