The AMRC Design and Prototyping Group (DPG) has carried out a study of self-supporting printed structures for UAV (Unmanned Aerial Vehicle) wing design.

The designers used fractal mathematics to model an internal structure for a wing resembling that of an insect wing.

The aim was to develop a wing that could be printed by the fused deposition modelling (FDM) process, using Acrylonitrile Butadiene Styrene (ABS) without using additional material for structural support.
