EOSTATE MeltPool Monitoring brings quality to AM parts
EOS has launched a process monitoring and analysis system called EOSTATE MeltPool Monitoring. An add-on to the EOS M 290 DMLS (direct metal laser sintering) system, the tool paves the way for complete part traceability, as well as automated surveillance and analysis of the melt pool during the build process for every spot, layer and part.
EOSTATE MeltPool observes the light emitted by the melt pool. The key elements are a pair of photodiodes located on- and off-axis, a camera adapter, a signal amplifier and spectral filters to separate process light from reflected laser light. The associated software offers automatic data error correction and real-time process visualisation and evaluation.
For data analysis, the toolbox visualises data and enables the evaluation of indication clusters. Three advanced algorithms are deployed to obtain different data interpretations. From the collected data, conclusions on resulting part quality can be drawn. Note: see also Machinery feature
