SUNLU PLA+ Silk, 1.75 mm, 1 kg 3D Printer Filament, Blue/Purple/Red/Gold

The SUNLU PLA+ Silk Four-Color Filament is a 1,000 g spool of Silk PLA+ designed for FDM/FFF 3D printers. It produces a four-colour gradient across a single print, so there is no need to swap spools manually when making decorative or artistic objects. The formulation is aimed at users who care about surface appearance rather than mechanical performance. The material produces a glossy, silk-like finish suited to display pieces, figurines, and other visual models. It balances gradient colour transitions with print reliability at moderate extrusion speeds.

The filament can be loaded directly into a Bambu Lab AMS for automated material handling and is compatible with 99 percent of FDM printers, including systems from Creality, Prusa, and Anycubic. Proper extrusion requires a heated build plate to maintain bed adhesion during printing. The physical properties include a tensile strength of 50 MPa, a flexural strength of 78 MPa, and an impact strength of 3.5 kJ/m². Elongation at break is 11 percent. These figures point to a rigid material with moderate impact resistance, suited to indoor display use.
