Take your prints to the next level with Polymaker™ HT-PLA, engineered for creators who demand performance without the hassle. Designed to withstand temperatures up to 150°C, this next-gen PLA keeps its shape—even under extreme heat—no warping, no sagging, no compromises.
Prints Like a Dream
HT-PLA runs flawlessly on most FDM printers using standard PLA settings—no upgrades or tuning needed. And with print speeds up to 300mm/s, you’ll get pro-quality results faster than ever.
Eco-Friendly Meets Engineering-Grade
Get the reliability and sustainability of PLA with the heat stability of advanced materials. No post-processing required—just print and go
14 Bold, Vibrant Colors
From prototypes to final products, match your vision with 14 rich, eye-catching colors that make every print stand out.
Need Even More Strength?
For next-level mechanical performance, check out Polymaker HT-PLA-GF —a glass fiber-reinforced version built for serious strength.
For higher temperature stability, and HDT properties you can anneal this material for 30 minutes @ 80-100°C. ( 100°C Recommended )

Can you anneal Polymaker™ HT-PLA’s?
Yes, you can anneal BOTH for better Heat Stability performance, however only the GF
version will gain significant HDT properties.
What is in HT-PLA?
HT-PLA is a kind of PLA-based multiphase composites, its main structure is PLA
materials.
What is Heat Stability?
The ability to withstand high temperatures without deformation while NOT under a
load.
Can it print with PLA settings?
Yes! This material prints great with generic PLA settings.
Polymaker™ HT-PLA - Gradient Fire (120g cycle) - Red/Orange/Yellow
Are Polymaker™ HT-PLA’s hygroscopic?
It has similar hygroscopic properties to PLA.
Are Polymaker™ HT-PLA’s UV / Weather resistant?
Similar to generic PLA, no material-modification for UV/weather resistance, we need
further testing.
What is the shrinkage rate?
Very minimal, similar to generic PLA.
Is it dishwasher safe? (Food safety, water steam)
This depends on the 3D print and how sturdy it is. If you have thin walls they may be subject to warping due to the harsher environment.
Are Polymaker™ HT-PLA’s abrasive?
Polymaker™ HT-PLA is non-abrasive however Polymaker™ HT-PLA-GF has glass fibers so
you will need a hardened nozzle to prevent wear and tear on your printer.
Can you print Polymaker™ HT-PLA’s with a smaller nozzle?
Yes, you can use a smaller nozzle, like 0.2mm nozzle.
What is the highest speed you can print at?
HT-PLA you can print up to 300mm/s and HT-PLA-GF you can print up to 350mm/s.
Do all of the color have the same heat resistance?
Yes, all of the colors and variations have the same heat properties
Is it biodegradable?
The resin matrix of HT-PLA contains only a small amount of non-biodegradable
components. Therefore, we consider it to be a material with good biodegradability
similar to polylactic acid
Is it strong?
The layer adhesion is fairly low, not recommended for single wall prints.
Does it has fumes when printing?
It will be similar to standard PLA
Can I anneal HT-PLA in boiling water?
Yes you can, however if you have hard water with high mineral content, boiling your part can cause the minerals to form a white dust coasting on the surface.
Is this PLA also based on NatureWorks?
Yes
Does HT-PLA have similar chemical resistance as regular PLA?
Yes
What percentage of fiberglass will be in the HT-PLA-GF composition?
12%
Could CoPE work well as a support material?
Yes
Do you have to remove the annealed parts out of the oven immediately or let it cool
down in the oven after annealing?
