Dual metal Bowden hot end, 1.75mm filament, 0.4mm Nozzle
Boksburg Store : 2 In Stock
This Dual Metal Hot End is based on the original E3D Chimera Hot End design. This hot end is not manufactured by E3D, but is the generic version. This hot end is a 2 in 1 system with 2 hot ends in one heat sink for dual extrusion. It is simple to set the height of each hot end as the heat break clamps in the heat sink with two screws.
The filament is fed into the hot end via a 4mm PTFE tube which runs through the hot end down to the nozzle. This ensures a low friction path for the filament to run through. The hot end comes with 0.4mm brass nozzles, 12V heater cartridges, 100k thermistors and 12V fans.
Note: It is possible that the hot end might leak plastic at the heater block when it is used for the first time. This is because the nozzle was tightened at room temperature and when the hot end is heated up to printing temperature, a small gap is created between the nozzle and the heat break. To solve this, loosen the grub screw that locks the nozzle (if present) and heat the hot end to printing temperature. Hold the heater block with pliers and tighten the nozzle with a spanner a little bit at a time so that the nozzle seats on the heat break. When done, tighten the grub screw onto the nozzle again.
