Abstract Scope |
Digital Glass Forming uses a fiber laser to heat a glass filament at its intersection with the workpiece, enabling deformation through thermal diffusion. This method allows the glass filament to wet the glass substrate and form continuous structures. However, increased laser power risks excessive temperatures, causing vaporization and bubble formation, limiting deposition rates. This research explores glass deposition in horizontal, vertical, and diagonal orientations using the fiber laser and feedback from thermal and machine vision cameras. The aim is to achieve precision, repeatability, and automation in the process. Additionally, the research addresses the "tailing" phenomenon, where the end of the glass structure becomes pointed. By partially reheating the glass tail and allowing it to reflow, the process aims to produce smooth ends without vaporizing the glass or damaging the structure. The strength of joints between glass structures will be evaluated through shear, cantilever, and 3-point bending tests. |
