Custom stainless insulated actively cooled Hot-End - Contains no PEEK or PTFE, all metal design will withstand temperatures well in excess of that ever required for thermoplastic extrusion. Extremely mechanically strong.
This update to our previous design uses fewer parts, offers much better cooling, is more easily assembled and is directly compatible with standard 16mm extruder bodies. All CNC-machined parts assure quality and accuracy.
This hot-end has been tested to beyond 400 degrees centigrade, all heated parts are either steel, aluminium or brass. By using stainless steel insulation and active cooling we have reduced the distance in which the plastic transitions from ambient temperatures to extrusion temperatures to 2mm. An extremely short transition from cold filament to molten plastic provides highly precise extrusion with little extrusion force.
The fully assembled hot end emulates J-Head style mounting, and should fit most extruder bodies accordingly.
It is UK based, but they ship worldwide.
This is pretty awesome, and it opens up some amazing new opportunities for high-temp printing. Rich talks about it at the bottom of this post: http://richrap.blogspot.com/2013/04/3d- … nt-in.html
I would order one for sure, but I already spent enough on my J-Head for now 
Here is the e3d picture:
