In Operando Monitoring by Analysis of Backscattered Electrons during Electron Beam Melting
Electron beam melting (EBM) is an additive powder-bed fusion process, which builds up bulk metallic components by a defined sequence of process steps. Like other additive processes, EBM enables the cost-effective fabrication of complex components in small batches. Nevertheless, to compete with conventional manufacturing methods, high-quality standards have to be fulfilled, which is currently seen as a barrier for the breakthrough of additive manufacturing technologies. Better insight by process monitoring is necessary but so far, there is still a lack of reliable tools for metal additive manufacturing. [...]
