SUNLU PLA High-Speed Marble, 1.75 mm, 1 kg 3D Printer Filament, Ashen Concrete

The SUNLU PLA High-Speed Marble 3D Printer Filament, Ashen Concrete, 1.75 mm, 1 kg, is a high-speed PLA material formulated for FDM and FFF 3D printers. Stone-like particles within the filament produce a matte, concrete-grey surface finish, making the spool well suited for architectural models and sculptures that require a natural stone appearance. A defining capability is its support for rapid extrusion, with a typical recommended print speed of 400 mm/s and a maximum of 600 mm/s. The material maintains consistent extrusion at these velocities to minimise warping, stringing, and clogging.

Compatibility extends to standard desktop systems that accept 1.75 mm PLA, including printers from Bambu Lab, Creality, Prusa, and Anycubic. For reliable feeding, the filament features a diameter tolerance of ±0.02 mm. Optimal printing requires a nozzle temperature of approximately 230 °C and a build plate temperature between 50 °C and 60 °C. The material exhibits a flexural strength of 72 MPa and an impact strength of 11 kJ/m². With a tensile strength of 41,000 kPa, the resulting prints offer measurable rigidity for display purposes.

• 1,000 g net filament weight supports extended printing sessions.
• 330,000 mm total wire length per spool.
• 164 °C melting point provides a specific threshold for thermal processing.
• Extruder temperature range of 190 °C to 260 °C accommodates varied hardware configurations.
• 1,250 kg/m³ material density.
• 25% elongation at break indicates material flexibility before structural failure.
