Polymaker HT-PLA 1.75mm Black 1kg Filament PA17005

Engineers and hobbyists who need high-temperature performance without the hassle of ABS turn to Polymaker HT-PLA. This filament prints like standard PLA but withstands heat up to 110°C after annealing, making it ideal for functional parts exposed to heat, such as automotive interior components, electronics enclosures, or kitchen tools. The 1.75mm diameter and 1kg spool ensure compatibility with most FDM printers and long print sessions.

Why choose it

HT-PLA combines the ease of PLA printing with the heat resistance of more advanced materials. After a simple annealing process, parts can withstand temperatures up to 110°C, far beyond standard PLA. This makes it perfect for applications where parts may be exposed to heat, such as in cars, near electronics, or in direct sunlight. Plus, it prints with low shrinkage and excellent dimensional accuracy, reducing warping and failed prints.

Ideal use cases

• Functional prototypes that require heat resistance
• Automotive interior parts (clips, mounts, brackets)
• Electronics enclosures and holders
• Kitchen utensils and tools (after annealing)
• Outdoor fixtures exposed to sunlight

Good to know

Annealing is recommended to achieve the full heat resistance. Place printed parts in an oven at 80°C for 6 hours, then allow to cool slowly. Note that annealing may cause slight dimensional changes; design parts with tolerances if high precision is required. Store filament in a dry, cool place to maintain print quality.
