SainSmart Assembled J-head Hotend Nozzle 0.3mm for 1.75mm Nozzle Fitting, 3D Printer Printing Filament Reprap MakerBot Kossel Delta

Removed the heat sink and added a series of vents to provide cooling. To
reduce weight, an aluminum nozzle is used.

This J-Head Hot End is designed based on other nozzle. It’s very simple by
reducing the number of custom machined parts to a bare minimum.

The J-Head Hot End can easily and well interface with the most popular RepRap
extruders. The filament path is same with the one of an already proven design,
it can be used to print reliably with both ABS and PLA. If using PLA, it
requires a small fan to provide air-flow through the cooling vents milled in the
sides of the nozzle holder. Besides, the Hot End has another two advantages.
Heat transmission is more efficiency as there is no thermal junction where a
separate heater screws onto the nozzle. And a resistor is used as a heater.
There is no need to wrap nichrome wire or to bake a heater core.

Features:

* Resistance of resistor 4.7Ω

* Resistor rated power 8W
