The Flashforge Creator 3 3D printer features an Independant Dual Extruder System (IDEX).  This takes dual extruder capabilities to the next level.  Because the two nozzles are on separate carriages, you will not get height problems between the two nozzles and there also will not be contamination when running different materials.  The best is that you can double your printing speed by printing two parts at the same time.  This alone puts the Creator 3 in a league of its own.  What is even more is the printer is built on a solid steel frame, it has a removable built plate capable of temperatures up to 120 Deg C and it features WIFI and a built in camera for remove monitoring.  The filament spools fits snugly in the side of the printer and is monitored by filament runout sensors.  The hot ends are designed to run up to 300 deg C and is compatible with PLA, ABS, PETG, PVA, HIPS, Wood, Nylon and flexible filaments.
