It can survive fine when under no load. It probably fades color less than abs does actually. However When experiencing any kind of mechanical load - say, a tablet squeezing at the edges for a friction fit - it fails rapidly at elevated temperatures.
Yup, and any interior vehicle parts I’ve done that have any loads have yielded after any kind of sunny week or so.
Massively oversized parts can last a bit longer, but they just have very low creep temperatures.
That's exactly how I know. Made some very nice interior car parts and experimented with the 3 plastics. PLA failed in a day, PETG made it a week before it sagged too much to be usable, but ABS is still going.
Yeah, I haven’t bitten the bullet and tried abs yet, mostly because I’m not ready to setup ventilation and better temp control.
Asa seems to be another option, but I’ve been having too much fun printing TPU parts to bother.
ahhh, TPU is addictive isn't it. So squishy and flexy. I've even made gaskets out of it for an ATV- not good ones, because it fails to seal when too cold, but gaskets that still work nonetheless.
