Polymaker HT-PLA 1.75mm Teal 1kg

Polymaker HT-PLA is a high-temperature PLA filament designed for 3D printing applications that require improved heat resistance and mechanical properties. This filament combines the ease of printing of standard PLA with enhanced thermal stability, making it ideal for functional prototypes, jigs, fixtures, and end-use parts that may be exposed to elevated temperatures.

Advantages

HT-PLA offers a unique balance of printability and performance. It prints with the same ease as standard PLA, with low warpage and excellent layer adhesion, but can withstand temperatures over 100°C after a simple annealing process. This makes it a cost-effective alternative to engineering materials like ABS or polycarbonate for many applications.

Suitable for

• Functional prototypes requiring heat resistance
• Jigs and fixtures for manufacturing
• Automotive and electronic components
• Educational and hobbyist projects
• Parts that need to withstand hot environments
