For a car-interior part that must survive 80 °C with UV, the chooser puts ASA first (HDT around 95 °C, good UV resistance) and warns that it needs an enclosure; PLA is ruled out below 55 °C.Open the Filament Chooser — PLA vs PETG vs ABS vs ASA

What is the Filament Chooser — PLA vs PETG vs ABS vs ASA?
PLA is easy, PETG is tough, ABS and ASA handle heat, TPU bends, nylon wears — but which one does your part need? Set how strong it must be, how hot it will get, whether it must flex, how much UV and chemical exposure it sees, what difficulty you accept and what hardware you have (enclosure, hardened nozzle, dry box) and the chooser ranks twelve materials with a match score and the reasons.
Each result lists nozzle and bed temperatures, heat deflection, approximate price, pros and cons and a food-contact note. Values are typical manufacturer figures and vary by brand, so always check the spool's data sheet.
