The inert gas par excellence
Noble gas is 1.38 times heavier than air and has a low ionisation energy. Its weight determines the ability to protect the melting bath generated in 3D printing processes and promotes its management in the printing chamber (Powder Bed Fusion - PBF- process).

Nitrogen fo additive manufacturing
Under normal conditions nitrogen is an inert gas but which at high temperatures can react with some materials also used in 3D printing. The use of nitrogen in this process is indicated for austenitic steel powders.

Helium for additive manufacturing
Helium is an absolutely inert and very light gas. Its chemical and physical characteristics make it ideal for both PBF (Powder Bed Fusion) and DED (Direct Energy Deposition) 3D printing processes, but it is very rare and expensive, so it is mainly used in EBM (Electron Beam Machine) processes given the low gas consumption that this process has. In DED processes it is often used mixed with other gases.
