Mechanical Study Of Additive Manufactured Honeycomb Structures

The aim of this paper is to present the comparison of the behaviour of additive manufactured honeycomb structures with different geometrical features under quasi-static loading conditions. The regular hexagonal topology is described by two different parameters - wall thickness (t) and radius of a circle inscribed in a elementary cell (r) - which has on the relative density of the entire structure. The experiments were carried out on samples manufactured from ABSplus filament using Fused Deposition Modelling (FDM) technique of 3D printing. The geometrical models of tested topologies were calculated on the basis of MS Excel and designed in the CAD system.
