Just like the name, this 3D printing material has a luminous effect! The main composition is a mixture of phosphorescent pigment and PLA 3D printing material. During the day, the phosphorus in the material will absorb UV. Still, when placed in the dark, the phosphorus-absorbed UV will start to glow beautifully, making the usually smooth and creamy appearance produce unexpected results! Designed especially for your unique artwork! Come and experience the fun of lighting in the dark!
