Polymaker HT-PLA 1.75mm Black 1kg

Polymaker HT-PLA is a high-performance PLA filament designed for 3D printing applications that require enhanced thermal resistance. This material combines the ease of printing typical of PLA with the ability to withstand higher temperatures after a simple annealing process. The filament is vacuum sealed with desiccant to ensure optimal printing conditions.

Advantages

HT-PLA offers a unique balance of printability and heat resistance. It prints with minimal warping and odor, similar to standard PLA, but after annealing, it can withstand temperatures over 120°C. This makes it ideal for functional parts that may be exposed to heat, such as automotive components or electronic enclosures. The filament has a diameter tolerance of ±0.05 mm, ensuring consistent extrusion and high-quality prints.

Suitable for

• Functional prototypes requiring heat resistance
• Automotive parts under the hood
• Electronic device housings
• Jigs and fixtures for manufacturing
• Educational projects needing durable parts

Recommendations

For best results, use a hardened steel nozzle if printing at higher temperatures. Ensure proper bed adhesion with a heated bed at 50-60°C. After printing, anneal the part at 110°C for 45 minutes to achieve maximum heat resistance. Store filament in a dry environment to prevent moisture absorption.
