Polymaker HT-PLA-GF (PA18005) - 1.75mm Glass Fiber Reinforced High-Temperature PLA Filament, 1kg, Black

High-temperature PLA filament reinforced with glass fiber, delivering exceptional stiffness and heat resistance for demanding 3D printing applications. The glass fiber reinforcement significantly increases rigidity and dimensional stability, while the high-temperature PLA base allows printed parts to withstand elevated temperatures after annealing.

Advantages

Glass fiber reinforcement provides high stiffness and low warping, making it ideal for functional prototypes and tooling. The filament prints with a matte surface finish, hiding layer lines for a professional appearance. After annealing, parts achieve a heat deflection temperature above 100°C, suitable for applications requiring thermal resistance.

Suitable for

• Functional prototypes requiring high stiffness
• Tooling and fixtures exposed to moderate heat
• Parts needing dimensional stability under load
• Applications where a matte surface finish is desired
