Creation of three-dimensional (3D) objects inside the transparent glass-ceramic (GC). (a) Schematic of the computer-controlled scanning system that employs two galvanometer mirrors and an optical lens to control light deflection and focus. (b) Blue (left), green (middle) and red 3D (right) objects were created by fast moving the laser focus using a computer-controlled scanner. The inset represents the object image that was generated by the computer.
