Effects of oxygen and moisture traces
3D printing is a layer-by-layer manufacturing process, and if the surface oxidises during the process, oxides are trapped in the component.
Since there is no possibility to reduce these effects subsequently and in order to avoid component losses, impurities by moisture and oxygen must be minimized as much as possible.
Gases we use
The PBF process commonly uses nitrogen with materials like stainless steel, or Argon for  reactive materials such as titanium or aluminum. We can help you select the best performing gas mixture for your DED or PBF process. Helium is another gas solution and is used in small quantities in the EBM process due to its properties. 

In addition, the FDM process uses argon, nitrogen and small percentages of hydrogen in argon, but only in the subsequent metal sintering operation.

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.
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. In 3D printing, nitrogen is mainly used for processing austenitic steels.
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.
