Abstract

The increasing need for fast delivery drives the development of drones as an alternative logistics solution. However, increasing payload capacity impacts thrust requirements, power consumption, and structural stability, necessitating integrated mechanical design. This study aims to design a mechanical system for a 2-3 kg package delivery drone with a stable and energy-efficient quadcopter configuration at maximum payload conditions. The method used is a design engineering approach through 3D CAD modeling, mass distribution and center of gravity (CoG) analysis, and thrust and power estimation using momentum theory. Evaluations were carried out on the total system weight, hover thrust requirements, hover power, and peak power with a thrust-to-weight (T/W) ratio of 1.8-2.0. The results show that at a total mass of ±6.5 kg, a minimum thrust of approximately 1.63 kgf per motor is required for stable hovering. The estimated hover power is around 1.04 kW, while the peak power is close to 3 kW. The 6S 15,000 mAh battery configuration is capable of providing a hover duration of approximately 15 minutes. This design demonstrates technical feasibility for medium-scale logistics drone applications.

Abstract

3D printing has rapidly evolved due to its significant advantages in rapid prototyping. 3D-printed products for industrial applications require stable mechanical properties, which are influenced by various factors. The lack of a comprehensive discussion addressing the factors affecting mechanical properties is the main reason for this review. This article aims to provide an overview of Fused Deposition Modeling (FDM) 3D printing concerning the factors that influence the mechanical performance of FDM 3D products using polylactic acid (PLA) material. The article covers the impact of material factors, process parameters (such as layer thickness, infill patterns, print orientation, infill patterns, infill density, infill width, temperature, and printing speed), as well as post-processing treatments as key considerations. The contribution of this article is to explain to researchers and industry practitioners the factors that affect the mechanical performance of FDM 3D printed products.
