A1 - Gumenyuk, Andrey T1 - Optical Sensor for Monitoring Quality of 3D Metal Printing N2 - Additive Manufacturing (AM) becomes widespread in many technological fields including the precise machining of steel. To assure quality of final products, thorough monitoring of online process is required. We test several monitoring techniques during the AM printing to quickly detect and possibly correct flaws while building a workpiece. Here we show how optical emission spectroscopy can be used to recognize defects that are artificially introduced on a steel printing substrate.

In the BAM project ProMoAM, results of different process monitoring techniques are combined to achieve quality assurance for the produced parts during the build. Here, first results of simultaneous measurements of optical emission spectroscopy and thermography during the laser metal deposition process using 316L are presented.
