Nitrogen for additive manufacturing

The inert gas that can become active.

Cheap but difficult to use

Under normal circumstances (temperature and pressure) this gas is inert, and when subject to high temperatures, it can become active influencing the result. It is usually used in the PBF (Powder Bed Fusion) 3D printing process, exclusively for stainless steel products. It is also used for the inerting of metal powders in the storage phase.

The use of nitrogen is often relegated solely to the processing of stainless steel powder.

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.
