Abstract

With the development of unmanned aerial vehicle (UAV) systems for a multitude of real-time applications, 3D printing technologies have been developed to make thermoplastic structures by fusing filament Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF). However, we consider that the realization of new technologies of experimental models / technological demonstrators / prototypes becomes profitable by using 3D printing technologies. The main aim of the paper is to highlight how the use of three types of materials, which are processed differently, influences the Von Mises stresses of the payload used for a UAV, with the mission of photographing and filming from high altitude.

Highlights

unmanned aerial vehicle (UAV) (Unmanned Aerial Vehicles) [1] are defined as generic air vehicles capable of operating autonomously, without a pilot on board [2]
Once the Textolite reaches the threshold of the plasticity area, it will suffer a rupture of the cotton fibers, the piece showing traces of exfoliation
ABS have some advantages over Textolite and PET-G: greater resistance to thermal degradation; greater thermal stability; a lower statistical dispersion of ABS compared to PET-G; increased flexibility in 3D printing

Summary

Introduction

UAVs (Unmanned Aerial Vehicles) [1] are defined as generic air vehicles capable of operating autonomously, without a pilot on board [2]. The most common types of UAVs are multi-rotor, fixedwing, flap-wing, and hybrid wing systems [2] (Figure). The most common types of UAVs are multi-rotor, fixedwing, flap-wing, and hybrid wing systems [2] (Figure1) They are considered very useful for activities such as mapping, topography, telecommunications [3,4], surveillance, and agricultural management [5,6]. Through the introduction of new lightweight materials and manufacturing technologies to enable the development of detection and control systems - payloads [14]. The use of additive manufacturing allows remote work, and the production of parts, close to the final requirements, consistently reduce emissions due to transport and delivery of parts to a desired location [15,16,17] (Figure 1)
