In order to advance from “Prototyping” to “Series Production” in selective laser melting (SLM), it is crucial to obtain proper understanding of how the microstructure of the final components is influenced by the processing parameters. Since its beginnings, microscopy has been used to assist both investigation and optimisation of manufacturing processes by allowing to observe the macro- and micro- structures of materials. Light, electron and x-ray microscopy techniques offer the possibility to measure many material features, such as, porosity, grain structure and crystallography - just to name a few, allowing for deeper insight and correlation with energy density and SLM processing parameters in general.
In this webinar, we will discuss how microscopy tools can be successfully employed in microstructure characterisation of selective laser melted parts and how correlative microscopy can be used in SLM quality control.
- How to use light microscopy to study SLM processing parameters
- How to use correlative microscopy for SLM quality control
- How laboratory diffraction computer tomography (LabDCT) can be used to characterize metal AM parts
