Abstract
Additive manufacturing enables the production of defined cellular and lattice structures. These additively manufactured meso structures offer various potentials like lightweight design or defined inner properties. To reduce the design effort a methodological approach is derived to enable fit for purpose design of components with meso structures using analytical calculation rules. The analogy to the analytical calculation of solid components emphasises the relevant parameters for the design as well as their influence on the properties of meso structures. Furthermore, based on the streamlined preliminary design, indications for the selection of suitable elementary cells regarding arising, even inhomogeneous, stresses are provided. The design method is exemplary applied to a cantilever beam.
