Analytical Calculation of the Mechanical Properties of Honeycombs Printed Using the FDM Additive Manufacturing Technology

چکیده
FDM 3D printed honeycombs are investigated. A honeycomb is composed of regular hexagonal cells. so that the fused filament runs along walls its We emphasize thickness these one or two times filament. When calculating mechanical properties a honeycomb, considered as Euler-Bernoulli beam bending in plane. To describe honeycombs, homogenization procedure used, which reduces to homogeneous orthotropic medium. An adequate analytical calculation this medium subject our research. Analytical formulae for presented. assess adequacy results, data compared with results simulation commercial ANSYS package. For this, made ULTEM 9085 material determined numerically. properties, from large number selected those predict them adequately. As result calculations, an prediction all obtained, exception in-plane shear modulus honeycomb. This due fact simulate such has use three-dimensional theory does not have description. thin aluminum was considered. In future, three-layer structures will be and similar.
