Electron beam powder bed fusion process monitoring by in-melt electron analysis

Additive Manufacturing
Insightful monitoring is accountable for good print quality by electron beam powder bed fusion (EB-PBF) which shows advantages among additive manufacturing techniques. The interaction of electron and matter provides a wealth of in-melt information simultaneously during the repeated local melting.

A new approach of preheating and powder sintering in electron beam powder bed fusion [PDF]

The International Journal of Advanced Manufacturing Technology
AbstractPreheating is an essential process step in electron beam powder bed fusion. It has the purpose of establishing a sintered powder bed and maintaining an elevated temperature. The sintered powder bed reduces the risk of smoke and in combination with the elevated temperature improves the processability.

Recovery of residual powder : For Electron Beam Powder Bed Fusion

Additive manufacturing (AM) allows production of complex parts, which would be hard to produce with conventional methods. Theoretically the technology is also more efficient with minimal material losses. However, with the AMmethod of powder bed fusion electron beam (PBF-EB) it has not yet been fully established if powder can be reused.

Vapor chemical composition in electron beam powder bed fusion using Ti–6Al–4V powder

The International Journal of Advanced Manufacturing Technology
This study investigates the vapor chemical composition, during the melting step of an electron beam powder bed fusion process using Ti–6Al–4V powder. A phenomenological model is proposed to analyze and discuss the vapor composition. The model focus on the heat dissipation of the molten powder.

In Situ Monitoring of Powder Bed Fusion Homogeneity in Electron Beam Melting [PDF]

Materials, 2021
Increasing attention has been devoted in recent years to in situ sensing and monitoring of the electron beam melting process, ranging from seminal methods based on infrared imaging to novel methods based on backscattered electron detection. However, the range of available in situ monitoring capabilities and solutions is still quite limited compared to ...
