POLISI3D Upgrade Light Universal DDB Dual Gear Extruder Bowden or Direct Drive Plated Copper Printhead Compatible with Ender 3 V2 / Pro / 5 Pro, CR10/ Cr-10S S4 S5 3D Printer TPU, 0.4mm

• This extruder is upgraded with two applications - Bowden drive or Direct drive, can switch them with the Connector adapters. And Double drive extrusion.
• We also upgrade the dual gears made from Hardened steel material and nickel plated and New design with Pulley bearings Hole to advoid the friction makes Higher lubrication and stable printing, Protects the gears and gearings, longer lifetime.
• This extruder weight with high torque small motor is around 203g, very light,makes your printing more stable. About the motor details , please check the specification picture in this listing.
• Heater block and 0.4mm nozzle are made from copper material and plated, which could reach up to 500C degree; A bimetal V6 heatbreak will come, which made from two components - Titanium TC4 and Copper, Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction.
• An installation plate makes this extruder compatible with 1.75mm Ender 3, Ender 3 V2, Ender3 Pro, Ender 5, Ender 5 Pro, CR-10, Cr-10S S4 S5 3D Printer

4010 cooling fan (Not included) is recommended for the heat dissipation part (4 threaded holes pre-tapped)of the extruder, and the heating block should be protected by a heating block holster (Not included) to avoid scalding.
