Heat Ready. Impact Ready. Still PLA
Polymaker™ HT-PLA Pro is a tough PLA for functional parts that need better durability in real-world use. It prints as easily as standard PLA and keeps its shape without load in warm environments. It is made for makers, engineers, and print farms that need real durability without added printing complexity.
Won't sag up to 150 °C straight off the plate
Polymaker™ HT-PLA Pro is designed to keep its shape in heat-exposed environments without load. Its Vicat softening temperature reaches 148.3 °C straight off the build plate and 150.5 °C after annealing, tested off the plate with no load. For applications that require heat resistance under load, annealing is needed. A 30-minute anneal at 100 °C increases the Heat Deflection Temperature (HDT @ 0.45 MPa) from 56.3 °C to 107.6 °C. This makes it better suited for warm-use cases such as sunlit windowsills or parts placed near heat-emitting machinery.
2x PLA durability
HT-PLA Pro keeps strong thermal properties while improving mechanical performance. Compared with regular HT-PLA, it delivers more than 2x higher impact strength (9.94 kJ/m² vs 4.94 kJ/m²) and 30% higher Z-axis interlayer adhesion (26.8 MPa vs 20.8 MPa). This helps printed parts resist impact and splitting along layer lines.
Prints with PLA settings
Unlike many high-temperature filaments, HT-PLA Pro prints with standard PLA settings. It runs on most standard FDM printers, with no enclosure, no specialty hotend, and no complex tuning required. Supporting print speeds up to 300 mm/s, it can fit into existing production workflows with minimal changes.
Please note: Annealing is required for heat resistance under load

prints just like PLA this stuff is great!!!!!!!!!!
Great filament, just takes some tuning. But it will figure itself out.
I had seen an early review video on HT-PLA Pro and felt like I had the perfect project to try it out - a simple lid for my wife's facial wax heater. The things run quite hot to keep the wax at temperature but I wanted a lid to cover the molten wax for safety reasons. A temperature resistant material was called for.
I won't bore you too much with the design - think hemisphere with a large void under the dome where the wax container sits. Being that it had a curved top, I decided to print it right-side-up, which meant having a lot of support for the large void area.
I loaded up the HT-PLA Pro on my Bambu A1 Mini, modified a Polylite PLA profile to increase the nozzle temp a bit (per the box instructions) and set it to printing.
The result was flawless and all that support came out in one block with a slight tug with plyers, leaving a very smooth interior. All of the surface areas were excellent and after several days of use my wife is very pleased with it and there are zero artifacts or any sort of warping.
It is a big deal when you order Pink and they give you 2 Purple rolls. Now I won't be able to make an item for a client and lost business! I truly doubt Polymaker will make this right, seems another reviewer got Purple instead of Pink. Definitely a quality control issue!
Also Fake 5 star reviews from L.H. 3 reviews try to boost ratings
We are very sorry about this! There was an initial issue of our SKU syncing wrong but that has been fixed and we are happy to replace with no return needed! Just reach out to support@polymaker.com and we can get that handled for you.
As for fake reviews - we certainly are not making any reviews! I see the 3 duplicate reviews now and will remove two of them.
EDIT: Well looks like I am unable to remove verified reviews from customers even when they seem to be duplicates like this - I am sending to web team to investigate.
This review is mainly here to balance out the silly person who gave a new product a 1 star review because polymaker mixed up purple and pink, oh the horror.
My first order of 10 rolls showed up perfectly and my first print in HT-PLA-Pro also printed perfectly. It is a high impact object where previous HT-PLA’s have not worked well because of layer adhesion issues. Only time will tell, but so far so good.
I’ll be leaving this test print in my hot car to watch for warping. If this review is still at 5 stars, assume everything has worked out well.
I printed the obligatory Benchy and a couple other items to test. This prints flawlessly right out of the box. I used the Polymaker HT PLA Pro profile settings for my printer. I am looking forward to doing more with PLA that I don’t need to worry about getting too hot or leaving it in the car.
I’m missing the roll of pink ht pla pro, you have sent a purple in its place. I would like to request a correction though the website has made it very difficult. Money back or correction because you messed up please.
We are sorry if there were any fulfillment issues! Please reach out to us at support@polymaker.com with photos and order details and we can help further!
Great to work with. Prints like butter. Soo far, prints stand up to heat in the car, so great for kids toys. Guess I may have to get L colors in my inventory

Excelente producto, se fue a impresión directo de la caja, no hubo tiempo de secado y la impresión fue muy buena
Great filament for me. I have done some strength tests, both before and after annealing, and have been very impressed. My post annealing horizontal force test came in above ABS. Going to be using this for smaller parts until I find it's tolerances, but so far very impressed
