eSUN PLA-UV Color Change Filament - Purple 1.75mm

For optimal results, print eSUN PLA-UV between 190-220°C with a heated bed temperature of 45-60°C. Maintaining a consistent temperature within the printing environment helps prevent warping. A layer height of 0.1-0.2mm and print speed of 40-80mm/s are typically effective, ensuring good layer adhesion and surface finish for color-changing effects.

eSUN PLA-UV contains photochromic pigments that react to ultraviolet light, changing color when exposed to direct sunlight or UV lamps, and reverting to the original color indoors. To preserve this effect, store the filament in a cool, dry, dark place when not in use, and avoid prolonged exposure to direct UV light during storage.

While eSUN PLA-UV offers enhanced toughness and UV-reactive properties, standard PLA materials are generally not recommended for continuous outdoor applications. Prolonged exposure to direct sunlight and moisture can lead to degradation, reducing mechanical properties and potentially fading the color-change effect over time. For robust outdoor use, consider UV-resistant materials like ASA.

The eco-friendly paper spool reduces plastic waste, contributing to a more sustainable 3D printing ecosystem. It is designed for compatibility with standard filament holders and offers the same reliable feeding experience as traditional plastic spools, ensuring smooth printing without tangles or snags. This choice supports environmental initiatives without compromising performance.
