This listing is for a 1kg spool of 1.75mm PLA filament designed for FDM machines. The material features a silk finish that provides a shiny, reflective surface to finished objects. It is engineered to change colors gradually throughout the spool, creating a rainbow effect on printed parts without needing to swap materials manually.

The gradient transitions are designed to happen relatively quickly, ensuring that even medium-sized prints show multiple color shifts. This makes it a popular choice for decorative items, vases, and artistic models where a unique visual look is desired. The filament is compatible with most standard 3D printers that use 1.75mm diameter materials.

Using this silk PLA results in smooth surfaces that hide layer lines better than standard matte filaments. The material is easy to print with and does not require a heated bed, though one can be used for better adhesion. It provides a simple way to add professional-looking color variety to any 3D printed project.
