E3D Nozzle V4/ 4.1 and V5 E3Dâ€™s Nozzle consists of a Stainless Steel tube (thermal break), Aluminium heatsink and heater block with a Brass nozzle. V4 had only minor machining issues when first released, these were quickly rectified in V4.1. This nozzle has become loved, trusted and used by many in the 3D printing community. The E3D nozzle is quite heavy due to the size of the heatsink, it requires fan cooling for best performance and is ideal for most materials printing slowly (it has very little ooze and a short thermal transition zone) to moderately fast, for me the 3mm version maxes out at around 140mm/Sec (@218 Dec C PLA) but with more extruder torque it could go faster still.
Having a brass nozzle is a big bonus, you can easily clean and change nozzle sizes. Worked very well with ColorFabb Woodfill material (0.6 and 0.8mm nozzles). My Hot-end of choice for PLA printing.
E3D do make a dedicated Bowden hot-end, this has a lightweight plastic pneumatic fitting directly in the aluminum heatsink, or you can fit a Bowden adapter like the one shown above. Great for traditional geared and direct drive extruder systems, Reduced weight E3D hot-ends are planned, these will then be ideal for Bowden and Delta based printers.
