|---|---|---|---|---|---|---|---|
| 1 | Polymaker Polylite PLAThe PLA row people are asking about. Nozzle 190–230 °C (374–446 °F), bed 25–60 °C (77–140 °F), drying at 55 °C (131 °F) for 6 h. The sheet does not list an outdoor life or a UV-hours figure. | PLA | 190–230 °C (374–446 °F) | 25–60 °C (77–140 °F) | — | Datasheet | |
| 2 | Bambu Lab PLA BasicBambu PLA Basic technical data sheet V3.0. Nozzle 190–230 °C (374–446 °F), bed 35–45 °C (95–113 °F), drying at 50 °C (122 °F) for 8 h. Same gap: no outdoor rating on the row. | PLA | 190–230 °C (374–446 °F) | 35–45 °C (95–113 °F) | — | Datasheet | |
| 3 | Prusament PETGThe PETG fallback from the outdoor guide. Nozzle 240–260 °C (464–500 °F) and bed 70–90 °C (158–194 °F) on the Prusament PETG technical data sheet. Drying is not stored. | PETG | 240–260 °C (464–500 °F) | 70–90 °C (158–194 °F) | — | Datasheet | |
| 4 | Bambu Lab ASAThe ASA choice when the part stays in the sun. Nozzle 235–260 °C (455–500 °F) and bed 90–110 °C (194–230 °F). The ASA sheet adds drying at 80 °C (176 °F) for 8 h. Enclosure required is blank. | ASA | 235–260 °C (455–500 °F) | 90–110 °C (194–230 °F) | — | Datasheet |

Shade and a cool climate are the case where people report PLA surviving. Hot sun and a closed car are the case where it softens. Switch to PETG or ASA for the second case. The outdoor guide is the material ranking. This page does not replace it.
What the comments report
A comment on r/3Dprinting 1ew3jx5 says PLA prints last well over 5 years outside, and it mentions a light color and moisture. A second comment on that thread starts an Illinois outdoor-light story. The supplied text does not finish a lifespan number, so this page does not invent one.
A comment on r/prusa3d 1m2ycdo says PLA outdoors in the Stockholm area for more than 3 years was fine unless the place gets very warm, which that comment puts at 60 °C (140 °F) and above, and that a previous ABS part went brittle in about 2 years. Another comment on the same thread says a PLA sign in the sun is still there and warped a lot, and that PLA doorknobs on a south-facing door broke after about 6 years. Those are reports. They are not a catalog UV test.
The bank also lists r/BambuLab 1b9r3zz, r/3Dprinting t81zr7, and r/functionalprint 184n94a. The supplied excerpts for this page do not include a temperature from those three threads.
When to switch
Prusament PETG lists 240–260 °C (464–500 °F) and 70–90 °C (158–194 °F). Bambu Lab ASA lists 235–260 °C (455–500 °F) and 90–110 °C (194–230 °F), with drying at 80 °C (176 °F) for 8 h. How to print ASA is the enclosure and ventilation process. Heat and car interiors are the next questions when the part is more than "outside in the shade."
What the PLA rows do not say
PolyLite PLA lists 190–230 °C (374–446 °F), 25–60 °C (77–140 °F), and drying at 55 °C (131 °F) for 6 h. Bambu PLA Basic lists 190–230 °C (374–446 °F), 35–45 °C (95–113 °F), and drying at 50 °C (122 °F) for 8 h. Those are print settings. PLA has no outdoor-life column on this site.
Pros and cons
Pros
- The page is about PLA's limits. The general outdoor ranking stays on the outdoor guide.
- PETG and ASA are catalog rows with temperatures, which is the switch the summary names.
Cons
- Community reports conflict. Supplied comments describe multi-year outdoor PLA, a warped sign, and doorknobs that broke after about six years. The editorial summary says a season or two in hot sun. Both are reported here, and neither is a lab result.
- A comment's 60 °C (140 °F) threshold is that comment. It is not a glass-transition cell on these PLA rows.
Printer considerations
- A shaded porch and a south-facing dark part are different tests. The comments below disagree on lifespan, and this page does not average them into one number of seasons.
- A closed car is the heat case. One wall-count thread, cited on that page, mentions a PLA boomerang on a dashboard. This page does not turn that anecdote into a car temperature.
- ASA's listed bed is 90–110 °C (194–230 °F) on the Bambu row and 100–120 °C (212–248 °F) on Prusament ASA. An open printer that cannot hold that bed is a reason to look at PETG instead.
What the community says
The editorial summary says PLA softens in hot sun and degrades over a season or two, is fine in shade or a cool climate, and should give way to ASA or PETG otherwise. Supplied comments disagree on the clock. r/3Dprinting 1ew3jx5 says PLA prints last well over 5 years outside. r/prusa3d 1m2ycdo says PLA outdoors in the Stockholm area for 3+ years was fine unless it gets very warm, stated as 60 °C (140 °F) and above, and that a previous ABS print went brittle. Another comment on that thread says a PLA sign in the sun warped a lot and PLA doorknobs on a south-facing door broke after about 6 years. This page does not pick one lifespan and does not publish a UV-hours test.

Questions
How is this different from the outdoor filament guide?
That guide ranks ASA, then PETG, then ABS for a part that lives outside. This page stays on PLA: shade and cool weather on one side, hot sun and a closed car on the other, and the comments that report both multi-year survival and warping.
Is 60 °C (140 °F) the PLA softening point in the catalog?
No. A comment on r/prusa3d 1m2ycdo uses 60 °C (140 °F) as a warmth threshold for outdoor PLA in the Stockholm area. PolyLite PLA and Bambu PLA Basic do not list an outdoor softening temperature. Their nozzle and bed cells are print settings.
