Electron Beam Powder Bed Fusion
, 2020Electron beam powder bed fusion (EPBF) is a process in which an electron beam is used to scan a powder bed. In order to comprehend beam-powder bed interactions and the role of various process parameters such as scan speed and beam power, it is essential to know how a beam is generated and manipulated.

Functionally Graded Steels Obtained via Electron Beam Powder Bed Fusion
Key Engineering Materials, 2023Electron-Beam Powder Bed Fusion (EB-PBF) is one of the most important metal additive manufacturing (AM) technologies. In EB-PBF, a focused electron beam is used to melt metal powders in a layer by layer approach. In this investigation two pre-alloyed steel-based powders, stainless steel 316L and V4E, a tool steel developed by Uddeholm, were used to ...

Sintering during Electron Beam - Powder Bed Fusion (EB-PBF) of Ti6Al4V Alloy
Defect and Diffusion Forum, 2022The partial sinter between the powder particles during the electron beam – powder bed fusion (EB-PBF) process is fundamental to guarantee adequate thermal and electrical conductivities and conduct the process safely. The sintering degree is tuned by using the process parameters that, at the present day, are mainly optimised with an experimental trial ...

Spot melting sequences for complex geometries in electron beam powder bed fusion
Progress in Additive ManufacturingAbstract Spot melting in electron beam powder bed fusion is a current research focus. This method exploits the ability of the electron beam to jump almost instantaneously between individual spots. This leads to an immense freedom in scan strategy design compared to line melting and opens up a wide range of ...
