One of the big hassles of 3D printing, is keeping having problems with your extruder. It happens quite often that the filament gets stuck and the extruder is not able to push the filament any more. That's why Micron E.M.E Ltd has introduced an all-metal, "J style" hot end, featuring a detachable filament guide and nozzle module "DFGNM". All parts are made by a CNC machine. The all metal design allows printing over the wide range of plastic materials up to 300° celsius.

The new mechanical design enables fast and easy replacement of the most critical and problematic components: the filament guide and the nozzle, without the need to disassemble the heating block. It enables strong filament gripping by using high torque 1:13 gear motor and stainless steel 303 hobbed gear with special teeth profile. Another important feature of the design is that replacing the filament guide and the nozzle module does not change the nozzle height so it is not necessary to re-adjust the nozzle height.

The extruder prints with PLA, ABS, polycarbonate, nylon and PVA. Price for the Micron's extruder is US$ 289.95.

Arik - Just seen your message. I'm printing mainly with PLA, but also with ABS and sometimes Nylon. The results are great! very good thermal design! will post photos soon. THX!!!

Mario, Did you print already? what material are you using as the support? Any link to printed parts?

Mounted the dual micron 3dp extruder head on my mendel-max. took me a few hours to calibrate my machine, but now I have a printer which prints support material, for less then 2K$ !

Took some time but I've just received it, was worth waiting! now I need to figure what's the best way to mount this baby on my mendelmax :)

I wish my replicator had this extruder (frustrated from removing/assmeble the nozzle alllllll day long)

Those guys are fast, just bumped in their dual version >> http://www.ebay.com/itm/DUAL-HEAD-ALL-METAL-3D-PRINTER-EXTRUDER-1-75-FILAMENT-HOT-END-REPRAP-/181295108788?pt=LH_DefaultDomain_0&hash=item2a3607d2b4 The price is a bit higher then other dual extruders, but I guess that CNC machining parts worth it..

Makerbot (Stratasys) should learn from those guys!

Wish I had one on my Replicator..
