# 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.

<details>

<summary><strong>Can you anneal HT-PLA-GF?</strong></summary>

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

</details>

<details>

<summary><strong>What is High Temperature Stability?</strong></summary>

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

</details>

<details>

<summary><strong>Is it hygroscopic?</strong></summary>

Similar hygroscopic properties to PLA.

</details>

<details>

<summary><strong>Is it UV / Weather resistance?</strong></summary>

Similar to generic PLA, no material-modification for UV/weather resistance, we need further testing.

</details>

<details>

<summary><strong>What is the shrinkage rate?</strong></summary>

Very minimal, similar to generic PLA.

</details>

<details>

<summary><strong>Is it dishwasher safe? (Food safety, water steam)</strong></summary>

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.

</details>

<details>

<summary><strong>Can it print with PLA settings?</strong></summary>

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

</details>

<details>

<summary><strong>Is it abrasive?</strong></summary>

Polymake&#x72;**™** HT-PLA-GF has glass fibers so you will need a hardened nozzle.

</details>

<details>

<summary><strong>Can you print with a smaller nozzle?</strong></summary>

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

</details>

<details>

<summary><strong>What is the highest speed you can print at?</strong></summary>

HT-PLA-GF can print up to 350mm/s.

</details>

<details>

<summary><strong>Do all of the color have the same heat resistance?</strong></summary>

Yes, all of the colors and variations have the same heat resistance.

</details>

<details>

<summary><strong>Is it biodegradable?</strong></summary>

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.

</details>

<details>

<summary><strong>What is in HT-PLA-GF?</strong></summary>

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

</details>

<details>

<summary><strong>Is it strong?</strong></summary>

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

</details>

<details>

<summary><strong>Does it has fumes when printing?</strong></summary>

Similar to standard PLA.

</details>

<details>

<summary><strong>Can I anneal HT-PLA-GF in boiling water?</strong></summary>

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.

</details>

<details>

<summary><strong>Is this PLA also based on NatureWorks?</strong></summary>

Yes

</details>

<details>

<summary><strong>Does HT-PLA have similar chemical resistance as regular PLA?</strong></summary>

Yes

</details>

<details>

<summary><strong>What percentage of glass fiber will be in the HT-PLA-GF composition?</strong></summary>

12%

</details>

<details>

<summary><strong>Could CoPE work well as a support material?</strong></summary>

Yes

</details>

<details>

<summary><strong>Do you have to remove the annealed parts out of the oven immediately or let it cool</strong><br><strong>down in the oven after annealing?</strong></summary>

No, you can remove them immediately if needed.
