Explanation: In this technology, first the part is designed by the 3D CAD software, and then the file is transferred to the processing software where the geometry is sliced into thin layers. The material is melted by electron beam to fit the geometry defined by the computer model. Then the metal parts are made by layers forming via electron beam melting process in a vacuum chamber.

Explanation: In the electron beam technology, when the whole process from CAD software to metal formation is completed, then the net shape metal part can be cleaned and finished by any conventional methods. Finishing and cleaning are very necessary and important for a casting to be used in applications.

Explanation: In electron beam melting process, the electron beam is generated by a device called electron beam gun which is generally located at the top of a vacuum chamber. The Electron Beam Gun is fixed and the beam is deflected to arrive at the desired area, which can melt the metal to form the desired shape of metal parts.

Explanation: In electron beam melting technology, the electrons are emitted from a filament which is generally heated to very high temperature. Then the electrons are accelerated to half the speed of light in the electric field. The beam of electrons is mainly controlled by two magnetic fields in the vacuum chamber. No object can achieve the speed equal to the speed of light in the universe.

Explanation: Electron beam melting is a vital technology in industries. This method has many advantages like high strength properties of metal, high energy level and the most important is the negligible impurities in the metal parts, because this process uses a vacuum chamber that eliminates the all kind of impurities like oxides, nitrides etc.

Explanation: In electron beam melting technology, the vacuum chamber is used which requires maintenance time to time and a shield is also used during the process which covers the x-rays produced by the electron beam in the process. These all expensive equipment are used which makes this technology very costly.

Explanation: The operations of fabricating 3D part in the electron beam melting (EBM) are very similar to that of laser beam melting (LBM). However, the major differences between the two systems are the different thickness of powder layer and different building speed which is generally high in the LBM system which gives rise to more rapid cooling in the fabrication of small size specimens.

Explanation: The electron beam melting (EBM) process can produce hollow metal parts with internal features, which are not easily produced by any other method. The EBM technology can provide the required mechanical strength and many properties with much less mass of the metal parts. This reduces the cost involved in the raw materials and the weight of the component.

Explanation: Electron Beam Melting (EBM) is a rapid manufacturing process in which when the high-speed electrons emitted from the electron beam gun, strikes the metal particles, the kinetic energy is instantly converted into the thermal energy. This makes a substantial increase in temperature above the melting point of the material.
