[Sintron] 3D Priner All Metal J-Head V6 Bowden Hot End 0.4mm Nozzle with Cooling Fan for RepRap 3D Printer MakerBot, Rostock, Kossel, and Prusa i3 1.75mm Filament Direct Feed Extruder 12V

Overview
After the success of MK8 extruder, Sintron launches its Bowden hotend into market with reasonable price and quality.
Why [Sintron] brand? there are so many cheap hotends in the market. most of them just put cheap metal pats together, and that's all.
That means you might get a bad quality easy jammed hotend. Unlike others, Sintron has done research about hotend for years, and already had success for MK8 extruder hotend. this ensures the quality of this Bowden version.

So better to choose a trustwothy brand, this can make sure your 3D printer get good print quality. What is the benefit of our Bowden hot end? Compared to normal J-head and others, this is with all metal structure. If you mistakenly heat the hotend over 280℃( this is possible by the temperature sensor error ect. ), traditional J-head would be melted and got damaged forever, with this one, it is fine or you just need to replace a nozzle.

The extruder is almost the most important part for 3D printer, also the most difficult part to calibrate. We have made necessary design to prevent "jammed" problem. I can't emphasize anymore how important this is, other sellers don't have this and would cause many problems.
This MK8 extruder is an open source universal suitable for most RepRap and DIY long distance feeding filament 3D Printers.
