SUNLU PLA+ Silk, 1.75 mm, 1 kg 3D Printer Filament, Blue-Green-Purple

The SUNLU PLA+ Silk Tri-Color Filament Blue-Green-Purple 1.75 mm 1000 g is a material for FDM and FFF 3D printers. It produces a colour-shifting surface effect that transitions between blue, green, and purple depending on the viewing angle. The PLA+ formulation is designed for smooth feeding and consistent extrusion during printing. A full spool provides enough material for decorative models, display pieces, and prototypes where appearance is the main concern. The filament gives a glossy, silk-like finish suitable for artistic and display applications.

It is compatible with standard desktop 3D printers that accept 1.75 mm filament. The manufacturer recommends a nozzle temperature of around 220 °C and a heated build plate temperature of 50–60 °C. A printing speed of 50 mm/s is advised to balance detail and material flow. The material is formulated for straightforward printing and smooth feeding without specialised hardware. These settings match standard PLA profiles on most FDM machines.
