SUNLU Easy PA Filament (black)

SUNLU Easy PA is a modern nylon filament (PA6/66 copolymer) that eliminates the biggest problems associated with traditional PA materials—cracking, warping, and excessive moisture sensitivity. It is designed to provide maximum strength and durability while remaining easy to print. It features high mechanical strength (tensile strength up to 75 MPa, flexural strength up to 98 MPa), good impact resistance, and dimensional stability thanks to low shrinkage. It also performs excellently at elevated temperatures—the heat deflection temperature reaches as high as 121°C, allowing prints to be used in demanding environments. The filament offers a wide range of printing parameters (250–280°C, 50–150 mm/s), a diameter of 1.75 mm ±0.03 mm, and a perfectly uniform, bubble-free structure, guaranteeing repeatable and professional results.

Print stress-free—no more cracking or warping

The biggest advantage of SUNLU Easy PA is its low shrinkage, which significantly reduces internal stress during printing. In practice, this means no cracks and minimal warping even with larger or more complex models. This allows you to print precise functional parts without frustration or material waste. Dimensional stability translates to better part fit and greater reliability of finished prints—exactly where it matters.

Strength and heat resistance in practice

SUNLU Easy PA combines high impact strength and flexibility with impressive heat resistance, making it ideal for demanding technical applications. Parts made from this material withstand impacts, loads, and operation at temperatures up to 121°C while maintaining their properties. It is the ideal choice for mechanical parts, components operating near heat sources, or wear parts. Additionally, the wide range of print speeds and temperatures allows you to tailor the process to your workflow—from precise details to rapid prototyping.
