Description
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 meta 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 trustworthy 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.
You might also need this all metal MK8 extruder to use with bowden hotend
