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 orthotro...

Due to the need for alternative materials realization of lightweight structures, analysis sandwich structures that have a semi-open thermoplastic honeycomb core as an internal support structure is great technical and scientific interest. Sandwich components with honeycomb-structured layer between two continuous fiber-reinforced face sheets exhibit maximum weight-specific stiffnesses strengths. ...

• Impact behavior of tailored honeycombs with bilinear wall-thickness gradients is studied. Tailored were realised via Digial Light Processing AM . Bilinear cell-wall thickness enhance energy absorption up to 250%. both impact resistance and concurrently. Enhancing the characteristics a material/structure without compromising its strength stiffness has been longstanding challenge in pursuit lig...
