In-situ monitoring systems can be extremely beneficial in this regard, as they allow to detect faulty parts at a very early stage and reduce the need for post-process analysis. After providing an overview of Additive Manufacturing and of the state of the art and challenges of in-situ defects...
Published literature shows defect formation during laser powder bed fusion additive manufacturing (AM) of nickel base superalloys are sensitive to alloy chemistry, processing conditions, and geometry. In this work, ability to detect spatial distributions of defects is explored using in-situ monitoring ...

In this paper, the progress of using acoustic techniques for AM process and part quality monitoring has been reviewed, and critical discussion has been made for the potential application of acoustic techniques toward quality inspection and monitoring in AM technology. 展开 关键词: acoustic emission (...
This article presents a millimeter-wave diagnostic for the in-situ monitoring of liquid metal jetting additive manufacturing systems. The diagnostic leverages a T-junction waveguide device to monitor impedance changes due to jetted metal droplets in real time. An analytical formulation for the time-...
