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.

Helium for welding
Low density inert gas. It is not usually used pure. It has a high ionisation potential, which on the one hand provides low stability and costly ignitions, and on the other hand, the advantage of being able to work with extreme parameters. This, together with its high thermal conductivity, provides highly energetic arcs and very fluid baths, which increases the welding speed.
