Abstract

A process for layer manufacturing comprising: (a) feeding raw material in a solid state to a first predetermined location; (b) depositing the raw material onto a substrate as a molten pool deposit under a first processing condition; (c) monitoring the molten pool deposit for a preselected condition using a detector substantially contemporaneously with the depositing step; (d) comparing information about the preselected condition of the monitored molten pool deposit with a predetermined desired value for the preselected condition of the monitored molten pool deposit; (e) solidifying the molten pool deposit; (f) automatically altering the first processing condition to a different processing condition based upon information obtained from the comparing step (d); (g) protecting the detector with a vapor protection device; and (h) repeating steps (a) through (g) at one or more second locations.
