Customers praised this heat-resistant filament for printing "like a dream" with "barely any layer lines" and smooth finishes. Most found it as easy to print as regular PLA while offering superior heat tolerance for outdoor/automotive applications. Some reported layer adhesion issues under heat, warping concerns, and color inconsistencies (yellows appearing dull/greenish).
great filament and doesn’t seem to cause any issues on my a1 mini!
It prints beautifully but failed in a hot car in less than an hour while the identical model in PETG didn't deform at all. I'm terribly disappointed in it.
Edited to add: per Polymaker's suggestion I repeated the print and annealed it at 100C for 30 minutes before testing it again. This time it performed the same as the PETG. The second photo shows the same model/same setting in PETG (far), HT PLA (middle) and annealed HT PLA (closest). I'm satisfied now, as the extra annealing step really isn't that big of a deal.
We are very sorry about this experience! HT-PLA will have heat stability under it's own weight up to 150C with no annealing required. But if the part is under weight/stress - it can deform closer to the 60C mark. Annealing can improve this but will only bring it to around PETG levels.
But unfortunately under weight like from this candle - I assume HT-PLA might not be the best bet. But we always stand behind our products so please reach out to the email listed on the spool with your order info and a photo of the spool where the batch number is located and we can certainly help further!
Prints great and looks great!! Used the blue it for my first nerf blaster!
Excellent quality
I printed a rather thin part and heated it to 65c, after an hour of this the parts snapped very easily along the layer lines. I will update if need be as I continue to print with it, but right now it is not what I was anticipating.
I'm using this for RC models and it's fantastic! Prints easily, barely any layer lines and so smooth. Performance matches appearance. I have ordered more for body parts as well.
Prints like a dream! I normally use PETG for outdoor/heat resistant projects but don't care for the print quality/shine of PETG. Love how PLA prints but ofcourse it won't survive the heat. Gave this HTPLA a try and so far so good. My only complaint is that the yellow is rather dull and almost has a light greenish hue to it, it's not as vibrant as I had hoped for coming from Polymaker.
Prints easier than PETG, ASA, PC, or ABS just as strong, with a comparable heat tolerance.
The color is rich and vibrant — a beautiful, true teal that looks great on finished prints. It feeds smoothly, layers cleanly, and I had zero stringing or clogging issues. The added heat resistance compared to standard PLA is a real bonus for functional parts. Highly recommend to anyone looking for a reliable, gorgeous filament!
Tangles on the roll, poor adhesion and warping using the recommended settings. Does not print just like pla.
Hey Ash!
We are sorry you are having a negative experience with our HT-PLA! We use auto winding without human interference so tangling should not be possible but we will still always stand behind our products and replace if this occurs. Please reach out to support@Polymaker.com with your order information and a photo of the spool where the batch number sticker is located.
Our HT-PLA should also print just like PLA without warping or having worse layer adhesion than standard PLA so that is odd! We can not only help to replace but also help to troubleshoot here.
HT-PLA is great.
The filament was very good. It printed smoothly and didn’t require very much change to the printing set up I had for regular PLA.
Extremely clean prints with great temperature stability.
Bought 5kg of red for a project and really wanted to make sure that it was gonna be heat resistant. the color is vibrant and print quality it perfect for parts that need to be interlocked and assembled. Will have to post a picture once the project is done.
Printing with Polymaker HT-PLA is a great experience! I need to print a project where a higher temp tolerance was a must but I wanted the ease of printing with PLA. HT-PLA was the perfect match and my prints came out great.
Looks great.
Best quality printing of any PLA that I have used no layer
Lines visible. Only filament I have found that is better is PLA-cf. but very limited color selection. I usually wait till it’s on sale for under $20 to purchase
I 3D print a lot of parts that spend time outside during the day. It's nice to not have to worry so much about direct sunlight. HT-PLA is so much easier to 3D print than PETG or some of the other more heat resistant filaments I've experimented with. A real game changer.
Some of the cleanest looking prints ive ever had. I love the matte finish it leaves
Can the ht-pla be used in the Bambu AMS without respooling it?
Yup! All of our spools have hardened edges to spin great in AMS like systems!
