Polymaker UV Color Change is a specialty 3D printing filament designed to change color when exposed to UV light. This innovative material adds a dynamic and interactive element to 3D printed objects, allowing them to shift hues in response to sunlight or other UV sources. The filament typically appears in one color under normal indoor lighting conditions, and transforms to a different shade or color when taken outside or placed under UV light. The change is reversible, so the object returns to its original color when removed from the UV light.
