There are 2 common ways to make the 3D head crystal engraving
1. Take a 3D picture by a specialized 3D Camera, and import the image into the laser engraving machine
2. Convert the portrait images (2D format) into a 3D image by using computer softwares, quality varies.
Laser Crystal Portraits — etch your favorite photo inside the solid crystal, there are normal few kind of the crystal for you to choose, different sizes and shape. And simply input the scanned Photo or 3D image (taken by the 3D camera) to the laser engraving machine, it takes few minutes to make a custom crystal portraits.
The sub surface laser engraving or SSLE is the process of engraving an image inside the surface of a solid material, which is typically a glass material with a good optical clarity to lessen the distortion of the laser beam. The sub surface laser engraving technique was discovered around 1980s in Russia.
For the crystals we refer here , it’s the gift product produced by the laser glass surfing machine. And custom
crystals are crystals of different shapes and sizes, which have one ore more 2D or 3D images etched inside the
crystal.
