Abstract:As 3D printing technology moves into large-scale commercial applications, ensuring consistency in products, especially when using concrete, is a significant challenge. Unlike traditional thermoplastic filaments used today, concrete possesses process parameters that can vary greatly and cause complete structural failure. Therefore a solution is to integrate real-time analysis of defects and correct them during the extrusion process. Specifically, we propose an optically precise linescan camera in two configurations as the main sources of feedback data. For testing, the sensors are directly implemented in the extrusion assembly and collect real-time data with a scale model machine. With the data gathered, we will qualify the design for the control feedback. Limits of self-adjustment, as well as the application to full-size operation, will also be reviewed.
