Polymaker™ HT-PLA-GF

This is an amazing filament. Perfect for everyday functional prints. If you want a natural non-smooth finish that shows minimal layer lines then look no farther.

prints as easy as PLA, but significantly better heat resistance, and the GF versions have a really nice textured finish that obscures the layer lines nicely.

I’ve used it for functional parts that are exposed to pretty hot temperatures inside our motorhome and they’ve held up very well.

I am in love! This filament is amazing to work with and definitely adds the next level I needed to do some work with PLA. I had some brand specific projects I wanted to do and wanted the colors to match. It was great to see them come to life.

HT-PLA-GF Grey printed on X1C using default PLC-CF profile, 230 C temp. Printed without any issue. Most importantly the supports came off very easily and cleanly. By far that is my favorite property of PLC-CF now GF. I hope they stock them as refills so they'll run better in an AMS.

Excellent heat resistance. Gives an amazing finish for walls. Just wipe down any parts you make with this to break off any glass fibers that are protruding.

Easiest fiber reinforced filament I have ever used. Easiest high temp filament I have used. Printing functional power tool parts for outdoor use.

Great to work with

Polymaker is my go-to source for filament, with an amazing color palette and an unbeatable, strong, tough series. I haven’t tried HT-PL-GF yet, but from the reviews I’ve read, everyone praises its strength and ease of printing.

EXCELLENT filament! I own mainly Milwaukee tools, and these new filaments are perfect! I have even turned some friends (they are all Makita) to your new colors!

Perfect for this project (PLA Filament Spool). It is a little finicky to print. Very Hard but also brittle. It broke in the PTFE tube once. High temperature characteristics were spot on, just as described. It has a very interesting texture. It feels nice to the touch, but the extruder had some trouble grabbing it.

I purchased this to print a battery holder for a friend and it worked flawlessly.

This is absolutely my favorite PLA to use!! Will continue using it unless an even better material comes out!

I love this filament. I designed and printed a phone holder for my car. The glass fibers make it look incredible. I've annealed the print, I've had no issues with softening in the car on a hot day. Also, it's about the only PLA I have that I don't have warping issues with, it's super stable and dimensionally accurate. It's my new favorite filament. Make sure you use a hardened nozzle with it.

I was very impressed with the PolyMaker HT-PLA-GF. I printed using .4 hardened nozzle with my Qidi Plus 4 with typical speeds used for PLA with additive in it. I push temps up to the 230C-234C, which for speed I run works out perfect in my experience after thousands of hours perfecting my Plus4 tuning. I then decided to anneal this filament to see full benefits. This was a very easy process and the results were very noticeable. Two parts of item I made when banged together rung out like solid wood.

I was very happy with my final results, will keep this material on hand for other unique projects that require the amazing tensile strength of PLA mixed with the high temp resistance found with Poly Maker HTPLA-GF. Do anneal your prints, this can very easily be done direct on your build plate if your part is not too thick. The result of annealing was impressive. Thank you PolyMaker for such a wonderful product. I will be purchasing your HT line more often going forward.

I would love to see PCTG from PolyMaker?

Good filament but does not work for structural parts in the heat. Annealing helps but I can achieve better results with GF ASA with no post processing

This is definitely my favorite PLA. It can withstand high heat temperatures. I already have stuff 3-D printed and put on my boat and it’s doing great. I love the texture of the Glassfield PLA it prints great if I had to give it a couple cons, it is stringy, but that can be fixed with just a little bit heat heat and I also printed at 250° C because I tried to get the best of layer adhesion and that’s the only other con. But it prints so beautifully

It prints like a dream, has the finish texture that you love of fiber filaments and won't turn into a puddle when accidentally left in your car! The support removal is impressive as well, it really does release from itself as a support material quite nice.

I live in Florida, so gear has to hold up to not only the 90+f temps and high humidity, it has to survive inside 110+f vehicle interiors. It's nice to be able to print something quick and easy that will survive those conditions. It's a nice, simple alternative to ABS or PA for some applications, without the need for a lot of dryer time, or annealing. Just print and go.

Also very impressed with the quality of the print without any tweaking, just used Polylite presets in Bambu Studio and it worked a treat.

This PLA is tough, very stiff, and stood up to being left in a hot car

Nice texture and amazing temperature resistance!
