Hello3D PLA UV Light Change White → Red is a special photochromic filament that changes from white to red when exposed to UV radiation (sunlight, UV lamp). After exposure ends, the color gradually returns to the original white. Suitable for eye‑catching models and practical indicators of sun exposure.
