Abstract Scope |
Small unmanned aerial vehicles that are fabricated with material extrusion additive manufacturing are often single-perimeter structures with sparse internal structure. The large distance between internal supports creates an ``unsupported wall distance'', which leaves the wall prone to deformation during fabrication. This work explores and quantifies the relationship between the deformation of the wing perimeters and two geometric parameters: (1) unsupported wall distance and (2) local surface curvature. An experimental study was designed to investigate this relationship. Wing sections of varying surface curvature and unsupported wall distance were built. The surfaces of the wing sections were then digitized into point clouds with a coordinate measuring machine, and the point cloud data were compared to the toolpaths used to print each wing section. The deformation data were then analyzed to quantify the relationship between deformation and the experimental parameters. |
