| Abstract Scope |
Glass Laser Additive Manufacturing is an emerging technology with a wide range of applications in chemistry, biology, optical science, and engineering. A custom printer was developed utilizing a 4-axis motion system, infrared radiation-based thermal sensors, and a CO2 laser to heat glass filaments above their working temperatures and deposit them into various shapes. Complex path planning is needed to deposit the glass to maintain a constant pulling action with the rod and maintain a melt pool between the rod and substrate or previous layer for printing. Similar path planning algorithms along with a feedback control system are used to alter the surface morphology of the deposited glass. To mitigate undesirable defects from overheating the glass, a closed-loop feedback algorithm automatically modifies the laser duty cycle given IR camera measurements to maintain a constant melt area temperature. |
