Principles of 3D printing techniques are briefly introduced. Based on the digital model file, the object is constructed by means of adhesive material, which is printed layer by layer. Then the research status of 3D printing glass is highlighted, including 3D printing glass with or without laser. Problems existing in the study of 3D printed glass are described. We further deepens the cognition of laser 3D printing glass technology through the detailed introduction of principle and application. Finally, we make a summary and future prospect about the emerging technique.
