# Does PLA creep or deform under a sustained load?

One comment says PLA creep shows up in joints and hinges, and that a static handle is a different case. Heat and sun are the other failure the comments name.

PLA creep, in the comment that uses the word, is a joint or a hinge under load. A part that only has to keep its length is a different case in that same comment. Sun and cabin heat are the other thread. Neither one is a creep rate.
## Joints, not a spear handle

[a Reddit thread in r/3Dprinting](https://www.reddit.com/r/3Dprinting/comments/1vro9bw/): "PLA Creep goes for joints and hinges and such. It won't matter in this case, no. Mythra will not have to switch to a spear because the handle elongated;)".

[a Reddit thread in r/3Dprinting](https://www.reddit.com/r/3Dprinting/comments/1afdylq/) starts with "A day or two" for regular PLA and a couple of perimeters, then reviews a wine. Do not file that as a lifetime.
## Heat is the other comment

[a Reddit thread in r/FixMyPrint](https://www.reddit.com/r/FixMyPrint/comments/ukqtmt/): "I would stick with ABS. I live in South Texas and that's the only thing that holds up to the intense heat and sun down here." is only "Make it colder outside." Outdoor sun and a closed car are [Can PLA be used outdoors?](/answers/pla_outdoor) and [heat](/answers/heat). [PLA versus PETG](/answers/pla_vs_petg) is the functional-part split.
## What the sheets actually list

[PrimaSelect PLA](/brand/primacreator/primaselect-pla) lists 190–220 °C (374–428 °F) and a bed of 30–60 °C (86–140 °F). The [heat-resistance dataset](/data/filament-heat-resistance) records HDT 57 °C (135 °F), ISO 75, load not stated. [PrimaSelect PETG](/brand/primacreator/primaselect-petg) lists 225–245 °C (437–473 °F) and 70–80 °C (158–176 °F), HDT 69 °C (156 °F), ISO 75, load not stated. [PrimaSelect ASA](/brand/primacreator/asa) lists 240–260 °C (464–500 °F) and 80–100 °C (176–212 °F), HDT 94 °C (201 °F), ISO 75, load not stated. Missing load means those three HDT figures are not a ranking. [Prusament PETG](/brand/prusament/petg) lists 240–260 °C (464–500 °F) and 70–90 °C (158–194 °F) on its technical data sheet and has no creep cell. [PLA](/material/pla), [PETG](/material/petg), and [ASA](/material/asa) are the hubs. [PrimaCreator](/brand/primacreator) is the brand index for the three HDT rows.

The comments do not say that. The second of those titles is about heat creep in a hotend, which is a different failure from a part sagging under load.
