Abstract Scope |
An in-situ process monitoring system was developed to track geometric and thermal data during large-format thermoplastic additive manufacturing (LFAM). The monitoring system is designed to repeatably mount near the nozzle and consists of dual stereoscopic depth cameras and eight thermal cameras. The data streams are gathered and combined utilizing a Robot Operating System (ROS) framework to synthesize top-down bead width and temperature information unobstructed by the nozzle and used for print validation. We present the hardware and software design for this system, as well as performance validation. |
