Rainbow or gradient PLA filament shifts colors gradually along its length, flowing seamlessly from one vibrant hue to the next—like red to orange to blue—creating a beautiful spectrum effect. As it prints, the changing filament produces smooth, multicolored transitions that make each 3D object visually unique and striking.

Dual or tri-colored coextruded PLA filament contains multiple colors aligned along the strand, so the printed model appears to shift in color when viewed from different angles. This creates a dynamic, iridescent effect where the object's surface seems to change hue with perspective, adding depth and visual intrigue to every curve and edge.

Translucent PLA filament has a smooth, glass-like appearance that allows light to pass through, giving printed models a soft, glowing quality. Depending on the color and thickness, the object can appear frosted or semi-transparent, enhancing details with a subtle, ethereal effect.
