  "slug": "outdoor",
  "useCase": "outdoor",
  "useCaseLabel": "Outdoor",
  "updated": "2026-10-14",
  "shortAnswer": "Use ASA for a part that stays outdoors in the sun. PETG is the cheaper community fallback, ABS is the third option, and plain PLA softens and degrades outside. Dark colors get much hotter in the sun.",
  "recommendedMaterials": [
    "asa",
    "petg",
    "abs"
  ],
  "printerConsiderations": [
    "ASA and ABS want a hot bed and a stable air temperature. Compare the row to the printer’s maximum nozzle and bed before buying the spool.",
    "An open printer is a reason to drop to PETG. The open-printer guide is the fit check. It does not change the outdoor ranking.",
    "Dark filament in direct sun is a heat problem on top of UV. The consensus does not give a temperature rise. It only says dark colors get far hotter."
  ],
  "pros": [
    "ASA is the default for long-term outdoor UV in this consensus, and the two ASA rows have listed temperatures.",
    "PETG stays on the list because it is the cheaper print when ASA’s temperatures are out of reach."
  ],
  "cons": [
    "PLA is the wrong outdoor default. The consensus is that it softens and degrades in the sun.",
    "A dark ASA part still heat-soaks. Color is not in the temperature table."
  ],
  "community": "The consensus is that ASA is the community default for long-term outdoor UV exposure, PETG is the cheaper option, and plain PLA softens and degrades in the sun. The materials named are ASA, PETG, and ABS. The caveat is that dark colors in the sun get far hotter.",

    {
      "q": "How is this different from the other outdoor guide?",
      "a": "That guide is the earlier ASA-first recommendation tied to manufacturer notes. This page follows this question’s consensus, which also names ABS and the dark-color heat caveat, and it cites a different set of threads."
    },
    {
      "q": "Does the catalog list a UV rating?",
      "a": "No. UV resistance is not a column. The ranking is the consensus order, and the temperatures are the product records."
