Abstract—The problem associated with the development ofspecialized equipment for the production of sheet elements ofaircraft structures is considered, taking into account the use oflayer-by-layer growth capabilities, optimization of the rig dieusing finite element analysis. Finite element modeling of thetooling used as a tool for sheet stamping was carried out. In thework it is proposed to use as a tooling a model of plastic materialobtained by layer-by-layer growing. As a structure of rigging,various grid structures were considered, an estimation of thestrong properties of this structure was made under the conditionsof the impact of the load from the press. In addition, acomparative analysis of models of optimized snap-ins constructedby layer-by-layer growth of the grid structure and topologicaloptimization due to material redistribution, based on loadingconditions. Analysis of the stress-strain state of the stamp iscarried out.
