Stacker Tungsten Steel Nozzles

Our new Tungsten Steel Nozzles are the perfect nozzle for nearly all applications. The hardness of these nozzles makes them perfect for carbon fiber and other highly abrasive “filled” filaments. These nozzles are NOT compatible with printers using our older single piece nozzles. Tungsten nozzles only fit our new Universal Heater Blocks, part number 90-142 and 90-143. These reprap type nozzles will also work great on all other printers using this same nozzle size. Length overall is 12.5mm and the thread size is M6-1.

  • Hardened Tungsten Steel
  • Low Friction Nano Coating
  • Rated up to 450C
  • For all Filaments

Our printer nozzles are available in a variety of sizes:

0.40mm nozzles are perfect for printing fine details in layer heights from 0.1 to 0.3mm.

0.60mm nozzles offer improved printing speeds with layer heights between 0.2mm and 0.5mm.

0.80mm nozzles are designed for bigger and stronger layers, and will dramatically decrease your total print times.  Use layer heights between 0.2mm and 0.7mm.


STACKER nozzles only work with 1.75mm diameter filament; Stacker nozzles will not work on 2.85mm diameter filament.

STACKER nozzles can be swapped out in seconds so you can quickly and easily match the nozzle to your specific printing needs – no more compromises. When changing nozzles, be sure to follow the nozzle installation process exactly to avoid filament jams.
