Electron-optical in-situ metrology for electron beam powder bed fusion: calibration and validation [PDF]

Measurement Science and Technology, 2021
AbstractA major advantage of metal additive manufacturing is the possibility for tool-free production of complex shaped parts. Currently, the geometrical and dimensional accuracy of these parts can only be reliably controlled by time and cost intensive post-process inspection, e.g. using x-ray computed tomography (XCT).

Recovery of residual powder : For Electron Beam Powder Bed Fusion [PDF]

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.

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.

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

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.

Prediction of Process Parameters for Powder Bed Fusion Using Electron Beam [PDF]

, 2020
Powder Bed Fusion med Electron Beam (PBF-EB) är en mycket komplex additiv tillverkningsprocess. Det finns ett fåtal antal material som går att använda i processen. Detta är ett förhinder för applikationer trots processens väldokumenterade fördelar över konventionell framställning. Framtagning av nya material är dock hejdad på grund av okunskap kring de
