How 3D Laser Engraving Works Inside Glass! 🤯
Have you ever wondered how intricate 3D designs are carved right into the center of solid glass without touching or scratching the outer surface?
It’s called Sub-surface Laser Crystal Engraving! A high-precision laser beam focuses entirely inside the glass at targeted 3D points . Just like focusing sunlight through a magnifying glass, the intense focal point creates millions of tiny microscopic fractures inside , shaping breathtaking 3D art while leaving the outside completely smooth!
