HT-PLA

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.

How long are the gradient transtions for HT-PLA?

Polymaker™ HT-PLA - Gradient Rainbow (200g cycle) - Red/Orange/Yellow/Green/Teal

Polymaker™ HT-PLA - Gradient Tropical (120g cycle) - Red/Yellow/Green

Polymaker™ HT-PLA - Gradient Ice (100g cycle) - Blue/White

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?

No, you can remove them immediately if needed.

Can HT-PLA be used as support material for higher temperature materials?

Yes! HT-PLA has been tested by the community and it does work as great support material for PET-CF. It may work for other high temperature materials as well, but so far only PET-CF has been tested.
