SUNLU Classic SB PLA, Matte, 1.75 mm, 1 kg 3D Printer Filament, Light Blue

The SUNLU PLA Classic SB Light Blue Filament, 1.75 mm, 1 kg, is a polylactic acid material designed for Fused Filament Fabrication (FFF) and FDM 3D printers. It is formulated for functional prototypes, decorative models, and detailed visual components. A matte surface finish helps reduce the visibility of layer lines on finished prints. Support structures produced with this filament separate cleanly from the model without leaving residue. The filament is wound neatly on the spool to reduce the risk of tangles during longer prints.

The spool feeds 1.75 mm filament with a diameter tolerance of ±0.02 mm, supporting consistent extrusion. The material is listed as compatible with the Bambu Lab AMS system, allowing automated loading in multi-material setups. Mechanical testing gives an impact strength rating of 18 kJ/m². The light blue colour offers a distinct appearance for visual prints. The spool measures 200 × 200 × 70 mm.
