Mechanical properties of two types of lattice structures fabricated with the use of hp multijet fusion technology

Popis výsledku v původním jazyce

Research in lattice structures and its application belongs to one of the most emerging disciplines in development of new types of engineering materials. High strength-to-weight ratio, special damping capabilities or auxetic behaviour are just a set of properties which can be directly influenced during design of these materials. Due to the geometric complexity of these structures, additive manufacturing is usually the only way to manufacture such a material. Among the others, HP Multijet Fusion additive technology with its supportless manufacturing approach offers one of the most convenient methods for production of lattice structures. Scope of this paper is design and mechanical testing of two types of lattice structures, namely body centred cubic structure and simple cross structure. Main attention is focused on printability of structures with different volume ratio in connection with their mechanical performance under uniaxial tensile loading. With respect to evaluated data, the cross structure shows more stiff behaviour for the same volume ratio and the same orientation in the build space of the machine. Body centred cubic structure on the other hand offers higher displacement to break.
