Effects of oxygen and moisture traces
3D printing is a multilayer process, and if during this process, the surface oxidises, then it remains trapped in the product.
It is precisely for this reason, these two pollutants must be reduced as much as possible, since there is no chance to repair damages, which translates into product loss.
Gases we use
The PBF process commonly use nitrogen withmaterials like stainless steel, or Argon for other types of materials. We can help you analyse what is the best performing mixture for your DED or PBF process. Another gas solution is helium, which is used in the EBM process, although being expensive for this process, it consumes a little amount.

On the other hand, the FDM process uses argon and nitrogen and small percentages of hydrogen in argon, but only in the metal sintering phase. For further information don’t hesitate to contact us.
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. 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 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.
