SUNLU PLA+ High-Speed, 1.75 mm, 1 kg 3D Printer Filament, Red

The SUNLU PLA+ High-Speed Red 3D Printer Filament is a 1.75 mm material for fused filament fabrication (FFF) 3D printers. It supports print speeds up to 600 mm/s when paired with a suitably configured hot end and cooling setup. The PLA+ formulation offers greater toughness and impact resistance than standard PLA, making it suitable for functional parts. Precise spool winding reduces tangling during long prints. The spool works with desktop FDM printers that accept 1.75 mm filament, including models from Bambu Lab, Creality, Prusa, and Anycubic.

The material feeds consistently, with a diameter tolerance of 0.02 mm, which lowers the chance of clogging at high speeds. The red polymer has a density of 1,230 kg/m³ and a melting point starting at 164 °C. A recommended nozzle temperature of 200 °C provides reliable extrusion, with a maximum supported temperature of 260 °C. Bed adhesion is maintained with a heated build plate set between 50 °C and 60 °C. The package includes a single 1 kg spool, with a total shipping weight of 1.3 kg.
