Heat resistant filament from Siraya is made to handle high temperatures without losing strength or shape.
These materials are perfect for parts that need to stay tough in hot conditions, whether that is in the kitchen, the car, or even outdoors under the sun.
With options designed for durability and stability, our heat resistant filaments give makers the confidence to print parts that will not warp or weaken when things heat up.
Why Choose Heat Resistant Filament?
When your project needs more than just strength, heat resistant filament delivers. It is built to keep its form under stress, even when exposed to higher than normal temperatures.
- ✅ Withstands elevated heat without warping
- ✅ Maintains strength and structure
- ✅ Ideal for functional, real-world parts
Everyday Uses for High-Temp Prints
Siraya heat resistant filaments are designed for practical use. They are perfect for parts that face heat every day, like car components, enclosures, or tools.
- ✅ Great for automotive and industrial applications
- ✅ Durable under repeated heating and cooling
- ✅ Helps prints last longer in harsh conditions
Built Strong, Built to Last
These filaments balance toughness with thermal stability. The result is prints that are strong, dependable, and ready for demanding tasks.
- ✅ High impact resistance
- ✅ Stable performance under heat stress
- ✅ Trusted for both hobby and professional projects
Heat Resistance Without Added Bulk
Heat resistant filaments from Siraya are designed to stay strong without needing extra material or bulk. ASA, for example, is naturally stable and performs well in heat without requiring thick walls.
- ✅ Keeps parts durable without excess weight
- ✅ Maintains shape in high-temperature settings
- ✅ Ideal for functional prototypes and final-use parts
And if your project needs even more flexibility with heat stability, check out our Silicone collection.
It combines softness, stretch, and heat tolerance, opening up new possibilities for molds, grips, and functional parts that face high temperatures.

Frequently Asked Questions on Heat Resistant Filament
What is the most heat resistant filament?
In the 3D printing industry, PEEK and PEI are among the most heat resistant filaments, withstanding temperatures over 200°C. They are commonly used in aerospace and medical industries. For everyday printing, filaments like ASA or polycarbonate also offer strong heat resistance.
Is PLA or PETG better for heat resistance?
PETG is better than PLA for heat resistance. PLA softens around 60°C, while PETG can handle up to 80°C before deforming. This makes PETG more reliable for parts exposed to moderate heat.
How to make PLA filament heat resistant?
You can make PLA more heat resistant by annealing it. This process involves heating the printed part in an oven at around 80–120°C for a set time. Annealing helps PLA parts withstand higher temperatures without warping.
Can PETG handle boiling water?
No, PETG cannot handle boiling water safely. Boiling water is 100°C, but PETG softens at around 80°C, which means it will deform under those conditions. For boiling water applications, a higher-temperature filament like polycarbonate is better.
