摘要

Fused Deposition Modeling (FDM), a convenient method to manufacture complex parts, has its drawbacks of uncontrollable defects, which often results in low precision of the desired product. An image-based monitoring system for plastic material FDM technology has been proposed in this study. During the FDM process, images of the nozzle are captured through the monitoring system. By calculating the real-time height, width and gathering pixel information of the product profile, criterions are then established to control the feed of the nozzle which can, in turn, ameliorate the precision and quality of the product.
