Polymaker HT-PLA Gradient Tropical 1.75mm 1kg 3D Printer Filament

Polymaker HT-PLA Gradient Tropical is a high-temperature PLA filament designed for 3D printing applications that require improved heat resistance and a vibrant gradient color effect. This 1.75mm diameter filament comes on a 1kg spool, vacuum sealed with desiccant for optimal storage. The gradient tropical color transitions smoothly between multiple hues, adding a unique aesthetic to your prints.

Advantages

HT-PLA offers higher thermal resistance compared to standard PLA, with the ability to withstand temperatures up to 100°C after annealing. It maintains excellent printability and low warpage, making it suitable for both beginners and advanced users. The gradient color effect provides a visually striking finish without the need for painting or post-processing.

Suitable for

• Functional prototypes requiring moderate heat resistance
• Decorative objects with gradient color effects
• Educational projects and hobbyist prints
• Parts exposed to higher temperatures (e.g., automotive interiors, electronics enclosures)

Recommendations

For best results, use a heated bed at 45-60°C and an enclosure to maintain stable temperatures. Anneal printed parts at 80-100°C for 30-60 minutes to enhance heat resistance. Store filament in a dry environment to prevent moisture absorption.
