Your second assumption is correct. There is not a flow meter alarm on
nitrogen flow - so as long as your O2 sensor is below alarm level, you will
continue to run, regardless of N2 flow.

  What happens to an SLS build (in a DTM 2500+ if that matters) if you run
out of Nitrogen.

  If the flow / pressure drops to zero. . .should the machine stop?

  Or will it keep running until the Oxygen sensor indicates that the build
chamberís level of O2 has raised too high?

  Thanks in advance for any input.
