Abstract
A system for inspecting a part while said part is produced by additive manufacturing, includes an additive manufacturing apparatus having a build tray, the apparatus being configured to fabricate the part layer-by-layer on the tray; an automated tool holder carrying a tool configured to deposit, add or weld layer-upon-layer of material; the tool holder and tray are configured to move relative to one another along a defined path; and an inspection device attached to the tool holder and configured to scan a layer of material in situ. The tool holder alternately arranges the tool and inspection device in a working position so that the tool holder fixes the tool in the working position for depositing, adding, or welding the layer of material and thereafter the tool holder switches said tool with the inspection device into the working position for scanning and detecting defects in the layer of material.
