Polymaker HT-PLA 1.75mm Orange 1kg

Polymaker HT-PLA is a high-temperature PLA filament designed for 3D printing applications that require improved thermal resistance compared to standard PLA. This filament combines ease of printing with enhanced heat resistance, making it ideal for functional prototypes and end-use parts exposed to moderate heat. The material is plant-based and biodegradable, offering an eco-friendly choice for makers and professionals.

Advantages

HT-PLA offers a unique balance of printability and performance. It prints at temperatures similar to standard PLA (190-230 °C) but provides a glass transition temperature of ~60 °C, allowing parts to withstand higher temperatures without deforming. The matte finish gives a premium look, and the filament is produced with tight diameter tolerances (±0.03 mm) for consistent extrusion. The spool and packaging are made from recycled cardboard, reducing environmental impact.

Suitable for

• Functional prototypes requiring heat resistance
• Automotive interior parts
• Electronic enclosures
• Household items exposed to warm environments
• Educational and hobbyist 3D printing

Recommendations

For best results, store filament in a dry environment and use a filament dryer if moisture absorption is suspected. Print with a part cooling fan for improved overhang performance. Ensure the build plate is clean and level. This filament is compatible with most FDM 3D printers that support 1.75 mm filament.
