Laser Beam Melting as a member of Additive Manufacturing processes allows the
fabrication of three-dimensional metallic parts with almost unlimited geometrical complexity and
very good mechanical properties. However, its potential in areas of application such as aerospace
or medicine has not yet been exploited due to the lack of process stability and quality
management. For that reason samples with pre-defined process irregularities are built and the
resulting errors are detected using high-resolution imaging. This paper presents an overview of
typical process errors and proposes a catalog of measures to reduce process breakdowns. Based
on this systematical summary a future contribution to quality assurance and process
documentation is aspired.Mechanical Engineerin
