(Only if the material has absorbed moisture)

For higher temperature stability, you can anneal this material for 30 minutes @ 80-90°C.

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 Heat Stability?

The ability to withstand high temperatures without deformation while NOT under a
load.

Are Polymaker™ HT-PLA’s hygroscopic?

Similar hygroscopic properties to generic 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.

Are Polymaker™ HT-PLA’s 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.

Can it print with PLA settings?

Yes! This material prints great with generic PLA settings.

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.

Does all the colors have the same heat resistance?

Yes, all of the different color variations have the same heat resistance.

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.

What is in HT-PLA?

HT-PLA is a kind of PLA-based multiphase composites, its main structure is PLA
materials.

Is it strong?

The layer adhesion is fairly low, not recommended for single wall prints.

Does it have fumes when printing?

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 coating 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 glass fiber (GF) is in the HT-PLA-GF composition?

12%

Why do we choose to not put the fiber content % in the name similar to Fiberon?

Polymaker™ prime materials naming convention is about keeping the naming
convention simple.

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.
