The use of laser line scanners for powder bed monitoring in 3D printing processes was investigated. It was possible to analyze dependencies in terms of exposure time due to the use of two different wavelengths of the laser line scanners. With a simplified setup – in accordance to a selective laser melting machine – the behavior of materials with nearly the same particle size as metal powder could be analyzed. In order to satisfy the conditions in the building chamber a construction platform was used. The behavior and the settings of the laser line scanner got evident, especially due to the strong reflections.
