HT-PLA-GF

Built for serious performance, Polymaker™ HT-PLA-GF combines high-temperature stability with enhanced strength and durability. Withstands up to 150°C without sagging or losing form - perfect for functional parts that need to endure the heat.

Effortless Printing, Supercharged Prints beautifully with standard PLA settings and supports speeds up to 350mm/s. Just load and go - no specialized tuning required.

Reinforced with Glass Fiber Tougher. Stronger. Smarter. HT-PLA-GF is glass fiber-reinforced, delivering higher stiffness and durability for demanding applications.

Note: This material is abrasive - use a hardened steel or ruby nozzle for best results.

Anneal for ABS-Like Heat Deflection Need even more thermal resilience? Anneal at 80–100°C for 30 minutes (we recommend 100°C)

9 Striking Colors Available in 9 bold shades, HT-PLA-GF brings serious strength and style to your prints.

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

Can you anneal HT-PLA-GF?

Yes you can anneal HT-PLA-GF for better heat stability and better HDT properties.

What is High Temperature Stability?

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

Is it hygroscopic?

Similar hygroscopic properties to PLA.

Is it UV / Weather resistance?

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.

Can it print with PLA settings?

Yes! This material prints great with generic PLA settings. You will just need a hardened nozzle

Is it abrasive?

Polymaker™ HT-PLA-GF has glass fibers so you will need a hardened nozzle.

Can you print with a smaller nozzle?

Yes, you can use a smaller nozzle, such as 0.2mm nozzle.

What is the highest speed you can print at?

HT-PLA-GF 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 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-GF?

HT-PLA-GF is a kind of PLA-based multiphase composites, it's main structure is PLA materials.

Is it strong?

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

Does it has fumes when printing?

Similar to standard PLA.

Can I anneal HT-PLA-GF 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 glass fiber 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.
