Abstract— Polylactic Acid (PLA) filament is one of the organic polymers that commonly wide-used in making a model by using a 3D Print method. This material can be applied on the UAV wing structure, by using semi- monocoque structure concept. The sizes of the wing structure components are determined by the forces acting on the wing itself, and derived into shear and bending moment stresses, so it created an optimum semi-monocoque structure to carry the load. This paper discusses the use of 3D printed PLA filaments for spars on the acrobatic UAV in order to optimize vehicle weight.

Index Terms— UAV, semi-monocoque wing structure, Polylactic Acid filament, 3D print, lightweight structure
