MICRON E.M.E  is introducing the second generation "all metal" extruder integrated with patent pending "all metal" hot end, featuring a detachable filament guide and nozzle module "DFGNM", a revolutionary solution for the most common problem with 3D printers: material being stuck inside the filament guide or the nozzle.

Unlike existing designs, 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.

Another important feature of the design is that replacing the filament guide and the nozzle module does not change the nozzle height so that it is not necessary to readjust the nozzle height. Thus such a maintenance operation is similar to replacing an ink cartridge on inkjet printer.


  • Innovative "all metal" hot end features a detachable filament guide and nozzle module "DFGNM"
  • All metal design" enables working with polycarbonate at 280- 300 degrees Celsius and with future materials that require higher working temperatures beyond those supported by plastic extruders and hot end.
  • Reliable design: enabling strong filament gripping by using high torque 1:13 gear motor and stainless steel 303 hobbed gear with special teeth profile.
  • Continuous idler bearing preload adjustment using 2 set screws.
  • Easy opening service door that does not change idler springs preload, while opening and closing the service door
  • Smooth filament feeding design that prevents the filament from being stuck after passing the hobbed gear.
  • Tested with PLA, ABS, polycarbonate, nylon and PVA.
