An all metal hotend based on a popular design. Only for 3mm diameter filament.
We use this hotend on all of our production machines, highly recommended upgrade.
Please be aware that this hotend does not include a heater cartridge or thermistor. Also be warned that 0.3mm nozzle requires a strong extruder and short confined feedpath as there is a lot of back pressure.
Pro-Tip: For those of you using an all metal hotend and have issues with plastic oozing through the heater-block threads, try heating your hotend up to 270'c and tightening the nozzle with a No. 8 spanner (don't get too carried away or you will damage the heatbreak, it's only 0.3mm wall stainless steel)
As the hotend heats and expands, the once tight fittings (at room temp) loosen up and potentially leak.
No customer reviews for the moment.
