A specific mixture for the Binder Jet and FDM (Fused Deposition Modelling) process
Under normal circumstances, this gas is inert, and when subject to high temperatures, it can become active influencing the result. It is uaually used in the PBF (Powder Bed Fusion) 3D pronting process, exclusively for copper alloys. This gas mixture is require for BJ and FDM process during the sintering post process.

Argon for additive manufacturing
Thanks to its chemical-physical characteristics, it is the most used gas for all additive manufacturing processes, mostly for those materials that are particularly reactive with oxygen or other air components.

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.

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.
