What is EBM?
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. Watch the video to see the process in action.
High productivity and lower cost
We worked with an independent consultant to evaluate the production costs of EBM compared to several laser machines. Two applications were selected for the study: a bracket for the aerospace industry and a hip cup for the orthopedic industry. Both applications were produced in titanium (Ti64). The consultant found Electron Beam Melting had a significant cost advantage compared to other methods.
"Depending on the characteristics of the part, the production cost per part can be up to 50% lower for EBM."
Frequently asked questions
What is the hot process?
Answer
During the hot process, the electron beam heats each layer of the build until the entire powder bed reaches an optimal process temperature specific to the material used.
As a result, the EBM process produces components without residual stresses and have microstructures free from martensitic structures.

How does the vacuum chamber work?
Answer
The Electron Beam Melting process takes place in a vacuum chamber to ensure a clean and controlled build environment.
Vacuum production is an important aspect of the EBM process as it maintains the chemical specification of the build material.

What is sintering?
Answer
During sintering, parts are produced free floating in sintered powder. This allows parts to be stacked tightly and limits, or eliminates, the need for supports.
What benefits does EBM offer the orthopedic industry?
Answer
EBM technology offers greater freedom of design, as well higher build volume builds, thanks to part-stacking capability. This combination allows for the manufacture of complex and detailed orthopedic implants.
There is a growing number of CE-certified and FDA-cleared implants on the market produced with the Arcam EBM technology.

What benefits does EBM offer the aerospace industry?
Answer
Aerospace is an innovative industry, and engineers are always searching for ways to make parts lighter, faster and more efficient. The EBM process allows you to produce lightweight components with a very efficient buy-to-fly ratio. EBM also allows you to additively manufacture parts using crack-prone materials.
