- Volumetric heating in digital glass forming(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2023-06-01) Deutsch Garcia, Luis; Ahuett Garza, Horacio; emipsanchez; Urbina Coronado, Pedro Daniel; Landers, Robert G.; Orta Castañón, Pedro Antonio; School of Engineering and Sciences; Campus Monterrey; Kinzel, Edward C.This research study investigates the use of volumetric heating in Digital Glass Forming (DGF) to enhance heat absorption and deposition rates in the glass printing process. A 1070 nm wavelength laser and various art glasses with colorants are explored to improve the volumetric heat absorption capacity of the soda-lime glass. A coaxial configuration is implemented to achieve uniform heating in filaments. The achieved deposition rates (V̇ = 15.7 mm3 /s) surpass previous reports in the literature. The study examines the behavior of glass material during printing and identifies different morphologies under varying conditions. Limitations include heat absorption restrictions within the glass and the occurrence of bubbles inside the filament. Simulation results suggest an optimal deposition rate where the glass can be deposited at higher speeds without encountering bubbles or defects by carefully adjusting the Optical Penetration Depth (OPD) of the glass filament This research contributes to overall DGF process, optimizing deposition rates, and identifying areas for future research. It demonstrates the potential of volumetric heating and lays the groundwork for advancements in glass manufacturing processes.
- A proof of concept system for the implementation of path planning strategies in the context of additive manufacturing of composites(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-06-05) Salinas Sáenz, Sergio Alejandro; Ahuett Garza, Horacio; ilquio/tolmquevedo; Orta Castañón, Pedro; Urbina, Pedro; School of Engineering and Sciences; Campus MonterreyIn recent years, the use of additive manufacturing (AM) technologies has increased significantly in industrial applications. In AM processes, which can produce complex shapes layer by layer, the end-product presents anisotropic properties that depend mostly on the deposition trajectory. The problem is that there is a bottleneck in research and improvement of these properties, due to limitations on the deposition trajectory control. In the case of commercial systems, the end-product mechanical properties are not taken into consideration, and the limited selectable options impedes the designer’s tool-path strategies to be implemented. This thesis presents a proof of concept system integrated by an adapted machine system and a software framework that allows the designer to implement and test the path planning strategies for the deposition trajectory control. An overview of the hardware conditioning is explained, and a proof of concept strategy is proposed for increasing the deposition trajectory continuity, as a proof of use of the system in the context of additive manufacturing of composites.
