For anyone else curious, the HT-PLA-GF is Glass Fiber. You'll want a hardened steel nozzle for that one.
Had no idea this existed, thanks for sharing! I haven't added venting for ABS/ASA, but this means I can still print accessories for my car.
Yeah, the HT line is relatively new.
I got a nice chunk a few weeks back on a PM. Otherwise, I'd by a few rolls now. I haven't even had a chance to mess around with it yet.
Hopefully we won't have the $10 or less per kg people. Polymaker isn't the same stuff. Elegoo is generally my go to just because Polymaker rarely goes on sale. outside of the PM, I haven't seen the HT this low since launch.

It's slightly less temperature resistant than PETG, so it may or may not be safe for your cat depending on your climate.
So just to understand this better, HT-PLA is better to print than PETG, but PETG is slightly better resistant.
And this is why HT-PLA exist?
I'm still trying to navigate the complicated world out 3d printing.
I'll try to answer without actually having used this HT-PLA yet (I think I'll mess around with some of the rolls I have this weekend).
The "HT" here stands for "high temperature" as generally PLA is not as temp resistant as PETG. PLA will print more precise and give you finer details and will handle overhangs better. The finish in my opinion looks much nicer on PLA than PETG - for the most part, I just don't love the shiny/glossy finish on most PETG. PLA is stronger but PETG has a little more flex. PETG is hygroscopic, so it can attain moisture easier and you need to ensure it's always dry. I do print with both, but for my purposes, I'd say I'm 80% PLA and the rest PETG combined with a few other filament types.
If you are just starting printing, I would suggest starting with PLA as it's a bit easier to print and then try PETG once you are comfortable.
PETG has a heat resistance of about 70 deg celsious.
HT-PLA does 107 deg celsius. a lot better than PETG and more importantly higher than the exreme heat of a hot car so it can be used outdoor and car
PETG is far more UV resistant, chemical resistant, abrasion resistant, water resistant and more durable than PLA by miles. This HT PLA is significantly worse in every meaningful way except heat resistance without a load.
The biggest thing people need to understand here is the heat resistance advertised is with no load!!! This HTPLA actually deforms under load at lower temps than regular PETG does. At a low load of .45 mba HTPLA deforms at 61c, PETG deforms at 78c. It only gets worse the more load is put on it. See for yourself. https://app.polymaker.com/compare
So no, this is not at all comparable to PETG unless what you are printing is 100% decorative.

"but this means I can still print accessories for my car."
No it does not. Performs basically the same as regular PLA under any type of load. Deforms at a much lower temp than regular PETG with any load applied. https://app.polymaker.com/compare
A lot of people misunderstanding things in here. This filament basically has no practical uses. Its for decorative stuff that needs heat resistance. Any load at all and it is pretty much identical to regular PLA.

Having printed HT-PLA-CF I can tell you that it is VERY sensative to moisture and will print like crap if not thoroughly dried before use.
I print both HT-PLA-CF and PETG regularly (almost daily lately) and I don't care what the data sheets and manufacturers claims are in my experience HT-PLA is more moisture sensitive than PETG.
This being said I can also tell you the HT-PLA-CF prints as well as PLA, gives a great surface finish, handles heat very well, is surprisingly strong and rigid while not shattering easily and if annealed per the directions can handle surprising temps under load. Layer adhesion is excellent also.

Thumbs up and repped. Thank you for sharing OP.
