PLA Color Change by Light

★ Product Features
We have two types of luminescent materials, one emits light at night: it maintains its original color during the day, but in the pitch black environment at night, it presents blue, green, and purple luminescent colors, which are very eye-catching. Another type of daytime luminescence: it is the original color indoors or without ultraviolet radiation, which absorbs the energy of ultraviolet radiation and produces color changes when exposed to sunlight or ultraviolet radiation outdoors. When it loses sunlight or ultraviolet radiation, it will return to its original color.
