Original abstract

This paper describes impact resistance of porous structures made by metal additive technology Selective Laser Melting (SLM). Porous structures are formed by repeated basic unit-cells composed of merged thin trusses. There were tested BCC types of structures made from material AlSi10Mg. Geometric parameters such as the diameter of the rod were changed .The samples were tested by the impact testing device with the spherical shape of the penetration body (indentor). The results show that the BCC structure with various truss diameter have various impact resistance and various energy absorbing capability.

Czech abstract

Tento článek popisuje odolnost proti nárazu porézních struktur vyrobených aditivní technologií Selective Laser Melting (SLM) z materiálu AlSi10Mg. Testovaná porézní struktura byla tvořena základní BCC buňkou, u které byly měněny základní geometrické parametry. Vzorky byly testovány na impaktovém zařízení s kulovým tvarem vnikacího tělesa. Výsledky ukazují, že struktura s různým průměrem prutu má různou schopnost absorbovat impaktovou energii.
