Presentation Title Customized Glove Box for In Situ Monitoring of Laser Directed Energy Deposition
Author(s) Sarah J. Wolff, Marwan Haddad
On-Site Speaker (Planned) Sarah J. Wolff
Abstract Scope This talk focuses on showing up-to-date features for a customized directed energy deposition (L-DED) glovebox system. The system includes a laser head with 4 nozzles, a laser controller, a 3-axis motor system, and powder hoppers for feedstock delivery. For closed-loop system control, an on-axis charge-coupled device (CCD) camera acquires images of the melt pool in real time which are then processed in LabView to control the laser power input and the motors scanning speed. Multi-material printing is enabled with remotely controlled powder hoppers that reside inside the glovebox. These are integrated with lab-based toolpath generation. Finally, these custom features can modify the resulting properties of printed components, including consistency, defects, and mechanical performance.
