SUNLU PLA+ Silk, 1.75 mm, 1 kg 3D Printer Filament, Red Yellow Blue

The SUNLU PLA+ Silk Tri-Color Filament Red Yellow Blue, 1.75 mm, 1000 g is a 1.75 mm printing material formulated for desktop 3D printing. It combines red, yellow, and blue pigments in a single spool to produce a continuously shifting tri-colour gradient that changes appearance depending on the viewing angle and lighting. This silk formulation is designed to give a smooth, glossy surface finish straight off the printer, with no post-processing required. Supplied on a 1000 g spool, the material is suited to decorative models, figurines, and display pieces where visual appearance is the main priority.

Mechanical specifications include a tensile strength of 50 MPa, a flexural strength of 78 MPa, and a flexural modulus of 2600 MPa. The material has an impact strength of 3.5 kJ/m² and an elongation at break of 11 per cent, indicating a balance of rigidity and slight flexibility. For best results, the extruder should be set to a typical temperature of 210 °C, with a build-plate temperature of 50 to 60 °C. The recommended print speed is around 50 mm/s to keep extrusion consistent. Operating within these ranges helps maintain dimensional accuracy and surface finish across the printed object.
