Powder bed-based additive manufacturing has become increasingly important for industrial
applications. In the light of this, qualitative considerations such as the geometrical accuracy, the
resulting mechanical properties, and the surface quality of additively manufactured parts must
be taken into account. Optical measuring techniques such as confocal laser scanning
microscopy, fringe projection and focus variation as well as profilometers are evaluated here, to
determine the surface quality of powder bed-based manufactured parts. Even though these
surface evaluation methods are established commercially, no standardized measuring procedure
has yet been established. Within an experimental study the validity and accuracy of surface
measurement methods are evaluated below, taking the limitations of each measurement system
and the comparability of areal surface textures into account. The examinations are carried out
with the powder materials EN-AW2024, Ti-6V-4Al and PA12, which are processed by electron
beam melting, and laser beam melting of metals and polymers. Guidance for a consistent and
comparable surface evaluation is thereby provided.
