How much helium could kill you? Quora

Helium is an inert gas, meaning it doesn’t do anything with your body. When you inhale it your body absorbs it via your lungs and alveoli into the blood stream and you will also eventually excrete it. It’s not toxic and therefor safe to breathe.

Helium gas, which is significantly lighter than argon and nitrogen, was successfully implemented in the LPBF process of Ti6Al4V. Helium and argonhelium gas mixtures enable a reduction in the porosity upon higher build rates. This is attributed to the positive balance of density and thermal properties offered by these mixtures. The obtained results could be used to initiate the development ...
