SainSmart Assembled J-head Hotend Nozzle 0.35mm 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

Getech Kossel Delta All Metal J-head Hotend with Line for Bowden Extruder


The Bowden principle:

The Bowden cable lets you reduce the moving mass of the extruder and thus allowing faster controlled motion, less shaking of your machine, less energy use and importantly: faster printing! Normally the mechanism that drives the filament into the hot end (where it melts) is directly on top of the extruder. This creates problems of balance and oscillations with faster motion which you can see in your printing results and hear and feel when your machine is shaking.

If the filament drive mechanism is placed on a non-moving part of the 3D printer, it can be pushed into a tube. PTFE (Teflon) is useful because it is slippery: it has little friction with the plastic.This limits wear and loss of energy. The tube’s other end is connected to the extruder’s hot-end.

The concept of using a Bowden cable as guide was suggested and pioneered by Ed Sells.

The main advantages:

All metal enables working with Polycarbonate up to 300 degrees Celsius and with future materials that require higher working temperatures beyond those supported by plastic extruders and hot end.

Tested with PLA, ABS, polycarbonate, nylon and PVA.

Features:

It is assembled with 4.7ohm 8W resistor and 100K NTC thermistor.

To make your printing easier,a 30x30mm 12VDC cooler fan is assembled for heat dissipation.

The inner diameter of the bowden feed mouth is 4mm to print with 1.75mm filament,and 6mm to print with 3mm filament.
