text: Additive Manufacturing (AM) processes generate plastic or metal parts layer-by-layer
without using formative tools. The resulting advantages highlight the capability
of AM to become an inherent part within the product development. However, process
specific challenges such as a high surface roughness, the stair-stepping effect
or geometrical deviations inhibit the industrial establishment. Thus, additively
manufactured parts often need to be post-processed using established manufacturing
processes. Many process parameters and geometrical factors influence the manufacturing
accuracy in AM which can lead to large deviations and high scatterings. Published
results concerning these deviations are also difficult to compare, because they
are based on several geometries that are manufactured using different processes,
materials and machine settings. It is emphasized that reliable tolerances for
AM are difficult to define in standards. Within this investigation, a uniform
method was developed regarding relevant test specimens to examine geometrical
deviations for Laser Beam Melting (LBM), Fused Deposition Modeling (FDM) and Selective
Laser Sintering (SLS) in order to derive geometrical tolerance values. The manufactured
test specimens were measured using tactile and optical systems to examine the
occurring geometrical deviations. The results show possible geometrical tolerance
values that were classified according to the international standard DIN EN ISO
286-1.
