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: "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 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: "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? and heat. PLA versus PETG is the functional-part split.
What the sheets actually list
PrimaSelect PLA lists 190–220 °C (374–428 °F) and a bed of 30–60 °C (86–140 °F). The heat-resistance dataset records HDT 57 °C (135 °F), ISO 75, load not stated. 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 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 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, PETG, and ASA are the hubs. 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.
Pros and cons
Pros
- The hinge-versus-handle distinction is a direct quote, including the joke that follows it.
- HDT figures stay labeled ISO 75 with the load missing.
Cons
- The bottle-shelf comment mixes a one-or-two-day guess with a wine review. It is not a test method.
- "Make it colder outside" is the whole comment. It does not name a material or a temperature.
Printer considerations
- A hinge or a joint is the case the score-52 comment treats as creep. A static spear handle is the case that comment says will not elongate.
- ISO 75 HDT figures on these PrimaCreator pages do not state the load. They are not a creep ranking against each other.
- The car and outdoor pages cover sun and a closed cabin.

Questions
Is a day or two the creep life of PLA?
That is the opening of a score-2 comment on r/3Dprinting, and the same comment then reviews a wine. It assumes regular PLA and a couple of perimeters. It is not a measured creep curve.
Does the catalog have a creep column?
No. PrimaSelect PLA, PETG, and ASA list ISO 75 heat-deflection temperatures of 57 °C (135 °F), 69 °C (156 °F), and 94 °C (201 °F), and none of those pages states the load. Heat deflection is not creep.
