Gas and Equipment for Additive

Special products for the additive manufacturing market.

Effects of oxygen and moisture traces
3D printing is a multilayer process, and if during this process, the surface oxidises, then it remain strapped 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 othertypes of materials. We can help you analyse whatis the best performing mixture for your DED orPBF process. Another gas solution is helium, which is used in the EBM process, although beingexpensive for this process, it consumes a littleamount.

On the other hand, the FDM process uses argonnitrogen and small percentages of hydrogen inargon, but only in the metal sintering phase. Forfurther 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. In 3D printing, nitrogen is mainly used for processing austenitic steels.
Helium for Additive manufacturing
The chemical and physical characteristics of helium make it ideal for PBF and DED 3D printing processes, it is often used mixed with other gases. Also, helium is mainly used in EBM processes which due to the low gas consumption.
