SUNLU Classic B PLA 1.75 mm, 1 kg 3D Printer Filament, Black

SUNLU PLA Classic B Black PLA Filament is a 1.75 mm material supplied on a 1 kg spool, designed for FDM and FFF 3D printers. It is formulated to support high-speed printing without compromising extrusion. The filament produces a clean matte black finish suitable for prototypes, decorative models, enclosures, and everyday functional parts, and the non-reflective surface aids detailed visual inspection. The polymer prints easily, making it usable for both beginners and experienced operators.

Standard desktop hardware accepts this material without specialised components. A heated build plate is recommended to aid bed adhesion. The polymer has a density of 1240 kg/m³, giving a total package weight of 1330 g. Mechanical properties include a tensile strength of 27 MPa, an elongation at break of 20 %, a flexural strength of 50 MPa, and an impact strength of 18 kJ/m². These values make printed parts suitable for moderately stressed applications.

• Print speed up to 600 mm/s
• Nozzle temperature range of 190 to 230 °C
• Typical extrusion temperature of 210 °C
• Heated bed temperature of 50 to 60 °C
• Diameter tolerance of ±0.02 mm for consistent flow
• Specific gravity of 1.24 g/cm³
