Abstract

In recent years, additive manufacturing (AM), primarily metal AM developed rapidly. AM has advantages such as energy saving, less material consumption, efficient production, and so forth. In-situ inspection is an important practice during the AM process which can help to improve product quality and reduce material consumption.
This paper presents the development and implementation of a layer by layer in-situ optical inspection system embedded within a commercial Ebeam machine. The inspection system is based on fringe projection profimometry. The system is applied for testing of the powder bed surfaces before melting and the solidified metal surfaces post layer processing. A novel high dynamic measurement method for the solidified metal surfaces was investigated. An example of high dynamic range surface during a part build is used to demonstrate the system capability.
