Nozzle Cleaning

Cleaning Filament

Extruder cleaning filament is a purging compound for plastic extrusion systems offered in a convenient form for 3D printer operators.
Temperature range from 130°C to 260°C. Actual usable temperature may vary due to differences in extruder construction.1)

How to Use

  1. Set extruder temperature to match filament in use.
  2. Pre-purge the extruder with natural colored filament (matching the filament type currently in use) to initially flush the extruder of color and contaminants.
  3. Unload filament.
  4. Slowly feed cleaning filament into hot-end. Use a series of stop-and-go motion to feed the material. Allow the purging compound to dwell for some time in the hot end before extruding it out the nozzle. The extrusion from the nozzle may be discolored and feel rough from carrying contaminants.
  5. When the extrusion is clear and smooth, cool down the extruder.
  6. When starting with new filament, set extruder temperature appropriate to the new filament. Feed new filament to purge the cleaning compound from the hot end.2)
