Ratings are relative, 1-5, for a typical filament of this type. Start from your filament maker's recommended settings.

Use it for

  • Outdoor brackets, garden fixtures, camera and sensor housings, vehicle exterior parts, and anything left in the sun and rain for years.
  • It keeps its color and strength where PLA, PETG, and ABS fade or crack.

Watch out for

  • Needs an enclosure and no drafts; it can still warp, though sources rate it slightly easier than ABS.
  • Fumes while printing. Vent the enclosure to the outdoors.
  • Costs more than PETG and ABS.

Tips

  • Use a brim and a hot bed for good adhesion, and print the walls a little thicker for outdoor parts.
