The effect of nodal topology on cellular solid mechanics: A preliminary diagnostic experimental investigation

Additive manufacturing allows material structuring, supporting the fabrication of multiple-level structures or metamaterials. Through the lens of classical stress reduction, nature’s cellular solid structures feature stress-homogenizing nodal topologies. Avian long bones are an example. Research into the mechanics of open cell cellular solids...

Mechanical Behaviour of PA2241FR used in Selective Laser Sintering

This research focuses on the possible causes of variation in the tensile strength and stiffness of witness specimens that are used in the manufacturing of aerospace grade selective laser sintered parts. Using specimens and data obtained from Materialise of the PA2241FR samples, the crystallinity and porosity of the samples was determined. The...

Implementing 3D printers to produce airworthy aircraft cabin parts

The research phase starts with an extensive literature study. To this end, a research question was drawn up, which reads as follows: What possibilities does Additive Manufacturing (AM) offer in airworthy aircraft part production and in what way can suitable parts be selected and redesigned? The most interesting findings from this literature...
