Metal Additive Manufacturing. Es gehört zu den generativen Fertigungsverfahren. Electron – beam additive manufacturing , or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts. The raw material (metal powder or wire) is placed under a vacuum and fused together from heating by an electron beam.
This technique is distinct from selective laser sintering as the raw. That is, that view assumes a powder-bed machine—a machine in which a laser or electron beam moves through a stationary bed of powder metal to create each incremental layer of .
Each layer is melted to the exact geometry defined by a CAD model. EBM Beam machine window . Electron beam additive manufacturing with wire (EBAMW) is a novel technology which can directly fabricate 3-D near-net shape elements from metal wires. Of specific interest are the additive layer manufacturing processes with wires that are capable for producing fully dense metallic and . This research evaluates the fatigue properties of Ti-6Al-4V specimens and components produced by Electron Beam additive manufacturing. It was found that the fatigue performance of specimens produced by additive manufacturing is significantly lower than that of wrought material due to defects such as porosity and . ADDITIVE MANUFACTURING.
SELECTIVE ELECTRON BEAM.
The powder bed is selectively melted layer-by-layer by an electron beam under high vacuum atmosphere. Electron Beam Melting (EBM) is a powder-based process for the additive manufacturing of 3D parts. Advantages compared to manufacturing. Electron beam melting (EBM) is an innovative additive manufacturing (AM) process in which metal powder or filament is completely melted by a concentrated beam of electrons. Production in a vacuum chamber ensures that oxidation will not compromise highly reactive materials like titanium.
Vacuum production is also . Alles über Electron Beam Additive Manufacturing. Aktuelle Nachrichten, Hintergründe und mehr zu dem Thema gibt es auf 3Druck. Many standard welding processes, such as gas metal arc-, laser-, or electron – beam welding, can be used for additive manufacturing (AM) with only slight adaptions. Wire-based additive manufacturing.
In this study, a three dimensional (3D) thermo-fluid model for the Powder Bed Electron Beam Additive Manufacturing (PB-EBAM) process was developed using ANSYS FLUENT software. Temperature dependence of both the surface tension and material physical properties was incorporated. In addition, the melt-pool .
