What is EBM process?
What is EBM process?
Electron-beam machining (EBM) is a process where high-velocity electrons concentrated into a narrow beam that are directed towards the work piece, creating heat and vaporizing the material.
What are the main differences between SLM and EBM?
Yet, there exist some differences between the two processes, as SLM operates under an inert atmosphere with a cold powder bed while EBM operates under vacuum and generally with a hot powder bed, which hence affects both the quality and properties of the fabricated parts.
When was electron beam melting invented?
1997
Electron beam melting (EBM) is a metal additive manufacturing technology that uses an electron beam to melt layers of metal powder. First introduced in 1997 by Swedish company Arcam, EBM is ideal for manufacturing lightweight, durable and dense end parts.
How are electron guns used in 3D metal printing?
Here, EBM technology uses an electron beam produced by an electron gun. The latter extracts the electrons from a tungsten filament under vacuum and projects them in an accelerated way on the layer of metallic powder deposited on the building plate of the 3D printer.
What is the full form of EBM in manufacturing?
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.
Is SLS the same as SLM?
“Selective Laser Sintering and Direct Metal Laser Sintering are essentially the same thing, with SLS used to refer to the process as applied to a variety of materials—plastics, glass, ceramics—whereas DMLS refers to the process as applied to metal alloys. …
What is difference between SLS and SLM?
In SLM, powdered material is melted, whereas in SLS the powder is heated below its melting point (sintering). When laser heats the powder material to below melting point, it forms solid by fusion. The working principle is almost same in both printing method.
What is a EBM printer?
Electron Beam Melting (EBM) 3D printers use a high energy beam that scans across a thin layer of metal powder causing localized melting and solidification over a defined cross sectional area. These layers are built up to create a solid part.
What is SLM printing?
Selective laser melting (SLM) is a specific 3D printing technique, which utilizes high power-density laser to fully melt and fuse metallic powders to produce near net-shape parts with near full density (up to 99.9% relative density).
What are the main functions of EBM in the manufacturing industry?
The EBM process utilizes a high-power electron beam that generates the energy needed for high melting capacity and high productivity. The hot process allows you to produce parts with no residual stress and the vacuum ensures a clean and controlled environment.

EBM Manufacturing is known for its Gentle Roll™ screener, EBM Manufacturing Aspirator, and Sidewinder™ belt drag conveyor. Also, we provide waterjet and plasma cutting services, custom flighting, metal forming.
What do you need to know about EBM process?
The EBM process allows you to produce light-weight components with a Buy-to-fly ratio very close to 1. EBM also allows you to additively manufacture with crack prone materials. EBM is an innovative technology for manufacturing orthopedic implants and aerospace applications.
Are there any implants made with EBM technology?
The U.S. implant manufacturer Exactech has also received FDA clearance for an acetabular cup manufactured with the EBM technology. Aerospace and other highly demanding mechanical applications are also targeted, see Rutherford rocket engine .
What is electron beam melting ( EBM ) technology used for?
Electron beam melting (EBM) technology has the power to help businesses build the next generation of applications, today. Offering high productivity and lower cost per part, EBM is an innovative technology for manufacturing in the orthopedic implant and aerospace industries.
