In-Situ Process Monitoring on EWI’s Open Architecture LPBF System (LM2B.1)
Presenter: Ajay Krishnan, EWI

This invited talk will emphasize the importance of in-situ process monitoring in AM as a tool to aid NDE and process development. It will also cover recent research executed on EWI’s Open Architecture LPBF System.

Analysis of Melt Pool Inhomogeneity in LPBF Using Optical Process Monitoring Systems (LM2B.2)
Presenter: Jana Harbig, Technical University of Darmstadt, Institute of Production Management, Technology and Machine Tools

Process anomalies affected by unsteady process conditions due to scanning strategy are quantified by photodiodes and high-speed-camera in order to correct them with locally adapted parameters. This approach enables the homogenization of the process quality.

The Role of X-ray Computed Tomography in L-PBF Manufacturing (LM2B.3)
Presenter: Nick Brierley, diondo GmbH

X-ray Computed Tomography (XCT) is the key to quality control for additive manufacturing of critical parts by Laser Power Bed Fusion (L-PBF), facilitating process qualification and detailed inspection of both feedstock and parts in production.

In-Situ Monitoring and Ex-Situ Inspection Data Registration for Laser-Based Powder Bed Fusion for Metals (LM2B.4)
Presenter: Shaw Feng, NIST

This talk describes a procedure to register in-situ monitoring and ex-situ Inspection data for Laser-based Powder Bed Fusion for Metals. Methods to register data to a common coordinate system are described for establishing process-structure-property relationships.
