Machine Learning in AM: Layer-by-Layer Defect Detection in Powder Bed Fusion
Artificial intelligence (AI) techniques, including machine learning, are increasingly integrated into additive manufacturing workflows to interpret process data and analyze large datasets, such as layer-by-layer powder bed images. In powder bed fusion (PBF), each layer can be imaged and analyzed, providing a basis for data-driven assessments of process stability and part quality. In situ backscattered electron (BSE) imaging serves as an effective inspection technique, utilizing backscattered electron contrast from the solidified layer to detect density variations, cracking, and surface features.By combining machine learning with electron beam-based imaging, this approach demonstrates the potential for scalable, in-situ defect detection in additive manufacturing. It establishes the groundwork for future remelting strategies capable of using melt pool depth to close previously detected defects above a certain threshold in the next layer.AgendaOverview of how a supervised learning approach enables automated defect detection using sequential BSE image datasets, applicable for defect detection in serial production.Discussion of the model training process on a manually annotated dataset, allowing the model to associate BSE data with defect likelihood.Explanation of the inference process, where the trained detector evaluates new layer images, locates regions of interest, and outputs bounding boxes with associated confidence scores to assess defect likelihood.Assessment of model performance through precision and recall metrics, ensuring reliable identification of actual defects while minimizing false positives.

Powder Bed Fusion Mechanics: Electron Beam Technology
Powder bed fusion is a leading additive manufacturing technology for producing high performance parts with excellent mechanical and material properties. Among its variants, electron beam powder bed fusion (EB-PBF) stands out for its unique advantages, such as a vacuum print environment, powder bed preheating, layer by layer backscattered electron imaging and high energy density for refractory alloys. This webinar provides an in-depth technical exploration into how the electron beam in EB-PBF works, focusing on the physics and control systems behind the electron beam. This will include advanced electron beam capabilities, such as beam shaping, charge neutralization and melt pool correction strategies enabled by patented technologies. Agenda: How electron beams are generated and controlled for additive manufacturing and other industrial applications Key hardware innovations that drive melt pool stability and beam control Lessons from electron microscopy/lithography expertise that now power AM hardware How EB-PBF can print fully dense Tungsten and refractory alloys at extremely high melting temperatures

AM In-Situ Process Monitoring with Backscattered Electron Imaging
In additive manufacturing (AM), part quality must be verified layer-by-layer to avoid costly reprinting and delays. Most AM systems rely on optical cameras for this but resolution and image evaluation for defects can be limited. With electron beam powder bed fusion (EB-PBF), backscattered electron imaging (BEI) enables up to 100 times greater resolution and direct interaction with atoms in each layer, giving engineers precise, real-time insights into potential defects and layer integrity during their AM process. Join Jeol’s webinar to explore how this advanced in-situ inspection method improves quality assurance and unlocks new efficiencies in AM production. Agenda: Why traditional camera-based monitoring in AM can have limitations in defect detection per layer How backscattered electron imaging provides higher resolution per layer through atomic interactions How EB-PBF enables real-time, layer-by-layer verification and subsequent defect correction How this approach enhances production reliability and part quality
