There are a lot of Polymaker Filament options built in to the firmware. Way more than other Brands which usually only have 1 type of filament like PLA. It would be nice to have a lot more types of filament options for the other brands (Elegoo, Amolen, Hatchbox, etc…). Could you include Polymakers HT-PLA and HT-PLA-GF with the next update?

Cool! It successfully imported:
I still have to set the shrinkage coefficient, but it’s same with everything else.
Anyone else played around with the this HT GF PLA filament? I bought a roll of it off amazon and am trying it out right now to see whether it will eliminate curling on big prints.
If it really is high temperature of 150C… it could be amazing:
I’m going to start by confirming the essential parameters:
but at least this gives me a running start.
I measured Max flow at 30mm^3/sec, so I’ll derate to 26mm^3/sec instead of the given 24mm^3/sec in the profile. Meh, it’s a judgement call. 24 is only slightly more conservative.

I have some PET variants from Polymaker and a PC-ABS from sunlu. Going to have to create them myself.
Apparently without annealing its HDT is around 75C, or about the same as PETG.

Yeah, I don’t mind annealing. It’s new, fun, and another thing that can go wrong for me to bang my head against a wall over.
I ordered it the week I ordered the H2S. Jut to play with. I honestly have no current application for it.
No, it’s not. But it can handle more than a standard PLA. Bear in mind that the standard creepage of PLA applies…
Refer to this channel and video (highly suggest for material testing)
I measured the shrinkage factor to be: 99.85949518%
which is more shrinkage than I would have hoped for, because over a print that’s 320mm long it would translate into 0.42mm shrinkage. Is that enough to trigger a curl? I’m not sure what the threshold number would be for curling
Anyhow, I’ll give it a try and then I’ll know for sure…
Maybe it won’t be all that bad, because it’s the amount of shrinking from print temperature all the way down to ambient temperature.
This is the first time I’ve done a GF print. The surface has a definite texture to it:
How to describe it: stipled? Powder Coated? Orange Peel? Sand casted? Sand blasted? What would be the right term? Considering it’s PLA, it’s a heavy texture.
The print is the lower half of a rugged 6x6 gridfinity box, so it kinda goes with that theme.
Well, I got a bit of broken glass under one of my fingernails, where it became painful. Luckily I was able to pull it out, with a bit more pain, using tweezers. The fact that this happened so early in the testing pretty much killed my enthusiasm for this filament, unless it were encapsulated in something else. Maybe I was just exceptionally unlicky? Has this happened to anyone else here using a GF filament?
I’m pretty sure it happened because there was some stringing I had to break through with my calipers in order to do the shrinkage measurements. Perhaps with that out of the way, it’s now safe. Not sure.
Anyhow, consider this a PSA for anyone else considering the same.

Supports stuck to it a bit too well using the same filament. Given the sharp glass content within this filament, I’m reluctant to post-process it. So, I’m running another print using PETG as the support filament.
I think in terms of anti-warp, I’d like to find a plain non-fiber formulation, as it’s just generally less hazardous. If anyone has suggestions that would fit with that, please post. Next on deck for those testing purposes will be PLA+ 2.0. It won’t have the heat resistance, so it’s a tradeoff.
Reporting back: after playing around with this more, it seems that it’s not just the shrinkage factor that matters. The added rigidity also helps in avoiding curling.
OK, here’s a GF filament I wouldn’t have expected…
Tinmorry sometimes has interesting stuff (and I think people like their PETG), but they are on my “question mark” list so I really haven’t had much interest in trying more of their filament.
I love this HT GF but… I am finding the dimensional accuracy is quite bad. Corners are very round compared to PLA CF, and parts don’t fit together well. Otherwise I love the printability and the stiffness/aesthetics of this stuff. It says you can run it through an AMS but after hearing what it sounded like to retract it… I don’t think i’m going to do it again.
