Abstract Scope |
The advantages of Additive Manufacturing (AM) highlight the capability to become an inherent part within the product development process. However, AM-inherent challenges harm the industrial establishment, for instance the high geometrical deviations. Different process factors influence the manufacturing accuracy and lead to large dimension, form and location deviations. Published deviations are also difficult to compare, because they are based on several specimens that were manufactured with different processes, materials and machine settings. This fact emphasizes that reliable tolerances for AM are hard to define in standards. Within this investigation, a universally applicable method was developed to examine geometrical deviations for AM processes. The main aim of this method is the derivation of achievable tolerance values considering important influencing factors. Furthermore, due to the locally varying surface roughness of additively manufactured parts, several tactile and optical measurements were compared in order to select a suitable measurement method. |
