Machine Learning-Based Real-Time Tracking and Modeling of Binder Deposition in Additive Manufacturing
The approach employs computer vision algorithms for image segmentation to identify and isolate wetted regions from captured print bed images. By distinguishing binder-affected zones, the system enables continuous tracking of deposition patterns with high spatial and temporal resolution. The segmented image data is then used to train predictive machine learning models that characterize binder flow behavior, spread rates, and deposition uniformity across layers.
This method provides a non-invasive, automated monitoring tool that can detect deviations such as over-saturation, under-deposition, or inconsistencies in binder distribution—critical factors affecting part integrity and dimensional accuracy. The integration of data-driven modeling not only facilitates in-process quality assurance but also supports closed-loop feedback control and process optimization.
Experimental validation confirms the system’s ability to track binder behavior in real time and model key parameters influencing print quality. The insights derived from this analysis can inform adaptive control strategies, reduce material waste, and improve repeatability in AM workflows.
In summary, this work demonstrates how combining image processing with machine learning delivers a powerful platform for real-time analysis and predictive modeling of binder deposition. It supports smarter, more autonomous manufacturing environments and lays the groundwork for future advancements in precision AM process control.
