At this year’s Formnext in Frankfurt/Germany, EOS has launched the EOSTATE MeltPool Monitoring as an add-on to the EOS M 290 DMLS system. This innovative tool paves the way for complete part traceability as well as an automated surveillance and analysis of the melt pool during the DMLS® build process – every spot, every layer, every part. With the tool EOS expands its existing comprehensive portfolio of monitoring solutions for AM by adding this high-performance online monitoring which ensures even greater transparency of the complex build process. As such, EOSTATE MeltPool targets R&D and manufacturing customers with demanding quality requirements.
The EOSTATE MeltPool Monitoring allows to move part quality assurance from post- to in-process, as such not only supporting a better risk management, but as well reducing time and costs for quality assurance and as a consequence overall costs per part.
EOSTATE MeltPool observes the light emitted by the melt pool. Key element are two photodiodes located on- and off-axis, a camera adapter, a specialized signal amplifier and according spectral filters to separate process light from reflected laser light. EOSTATE MeltPool software offers automatic data error correction and real-time process visualization and evaluation. For data analysis, the EOSTATE MeltPool Analysis Toolbox visualizes data in 2D or 3D mappings and enables the evaluation of indication clusters. The tool works based on three advanced algorithms to obtain different data interpretations.
