Solutions for additive manufacturing

What Nippon Gases has to offer to the additive manufacturing industry

Effects of oxygen and moisture traces
3D printing is a multilayer process. This means that if the surface oxidizes during the process, it remains trapped in the product.
That's why Oxygen and moisture must be reduced as much as possible. There is no chance to repair damages, which results in product loss.
Gases we use
For the 3D printing of metals, we use Argon or Nitrogen, depending on the type of printer and the material that needs to be printed. In addition, we also use Helium in the EBM process.

In the sintering phase, executed after and not during the printing, the FDM process uses Argon, Nitrogen or mixtures consisting of small percentages of Hydrogen.

Argon for additive manufacturing
Thanks to its chemical-physical characteristics, Argon is a frequently used gas in the additive manufacturing processes. It's mostly used for those materials that are particularly reactive with oxygen or other air components.
Nitrogen for additive manufacturing
Under normal conditions, Nitrogen is an inert gas but at high temperatures it can react with some materials which are also used in 3D printing.
Helium for additive manufacturing
Helium is an inert and very light gas. Its chemical and physical properties make it ideal for both PBF and DED 3D printing processes. Since Helium is very rare and expensive, it is mainly used in EBM processes, which are known for their low gas consumption. In the DED process Helium is often used, but mixed with other gases.
3D Pro® sinter3 for additive manufacturing
This mixture is especially designed for the sintering process after the FDM process.
