The inert gas par excellence
A noble gas is 1.38 times heavier than air and has a low ionization energy. Its weight determines the ability to protect the melting bath during the 3D printing processes.

Helium for Additive manufacturing
Helium is an absolutely inert and very light gas. Its chemical and physical characteristics make it ideal for both PBF and DED 3D printing processes, but it is very rare and expensive, so it is mainly used in EBM processes given the low gas consumption that this process has. In DED processes it is often used mixed with other gases.
