Clogs and jams can be common with current 3D printer extruders, but Micron E.M.E Ltd hopes to curb that with their next generation all metal construction extruder. Micron’s extruder is built via a CNC machine and features a J style hot end, a detachable filament guide and nozzle module.

Unlike many extruders, Micron’s 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. Micron’s unique design eliminates the need to readjust the nozzle height after replacing the filament guide and nozzle module.

Other main advantages of the all metal design are working temperatures with polycarbonate up to 280- 300 degrees Celsius and the ability to print with future materials that require higher working temperatures. High torque 1:13 gear motors and stainless steel hobbed gears with special teeth provide reliability not seen in common extruders. Tested materials include PLA, ABS, polycarbonate, nylon and PVA at a resolution of 50 microns.
