SUNLU TPU Silk filament black 1.75mm TPU Silk B

SUNLU TPU Silk is a black flexible 3D printing filament with a 1.75 mm diameter, supplied on a 1000 g spool containing roughly 330 metres of material. The thermoplastic polyurethan combines the elasticity of TPU with a smooth, silky surface, making it suitable for both functional parts and visually appealing prints. Printed components bend without breaking, withstand impacts and everyday wear, and show an even, slightly glossy finish.

The properties can be tuned through your print settings. With no infill and 0.8 to 1.2 mm wall thickness, you get very soft parts, while 5 to 15 % infill and walls of 1.2 mm or more add stiffness and strength. Recommended speeds are 50 mm/s with retraction or 60 mm/s without on direct extruders, and 20 to 30 mm/s on Bowden systems. The filament performs best on models of medium height with limited overhangs.
