Argon for additive

A frequently used inert gas in the additive manufacturing processes

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.

Argon is adequate for all types of metal and (non-) ferrous materials.

Helium for additive manufacturing
Helium is an inert and very light gas. Its chemical and physical properties make it ideal for both PBF and DED 3D printing processes. Since Helium is very rare and expensive, it is mainly used in EBM processes, which are known for their low gas consumption. In the DED process Helium is often used, but mixed with other gases.
