Abstract

Desain frame quadcopter yang ringan dan kuat sangat dibutuhkan dalam riset dan perlombaan, namun penggunaan carbon fiber memiliki kendala biaya dan produksi. Penelitian ini mengembangkan alternatif menggunakan material PLA+ melalui metode Additive Manufacturing berbasis 3D printing (FDM). Perancangan dilakukan menggunakan perangkat lunak CAD (Autodesk Inventor), dilanjutkan dengan analisis topologi dan simulasi statis struktural menggunakan ANSYS. Proses pencetakan divariasikan dengan pengaturan parameter cetak (seperti: layer heigth, extrusion width, dan nozzle temperatur) untuk mendapatkan kualitas hasil terbaik. Selain itu, dilakukan pengujian pembebanan secara eksperimental untuk mengukur deformasi aktual. Dua desain diuji: Desain A (variasi ketebalan) dan Desain B (variasi lebar arm). Optimasi topologi menunjukkan pengurangan massa sebesar 65% (Desain A) dan 30% (Desain B). Simulasi deformasi statis menunjukkan Desain A lebih unggul dengan deformasi maksimum 0,227 mm dibanding Desain B sebesar 1,583 mm. Uji kekakuan menunjukkan deformasi 0,3355 mm pada Desain A yang merata dan simetris, sedangkan Desain B sebesar 0,3555 mm dengan distribusi deformasi lebih luas. Uji pembebanan aktual menunjukkan deformasi 0,045 mm pada pembebanan 100%, dan deformasi 0,16 mm pada pembebanan 200%, hasil ini membuktikan bahwa Sampel 6 secara struktural paling efisien dan layak untuk drone berperforma tinggi.

A lightweight and strong quadcopter frame design is essential for research and competition purposes; however, the use of carbon fiber presents challenges in terms of cost and production complexity. This study proposes an alternative by using PLA+ material through additive manufacturing based on 3D printing (FDM). The design was created using CAD software (Autodesk Inventor), followed by topology optimization and static structural simulation using ANSYS. To achieve optimal print quality, the printing process was varied by adjusting print parameters (such as layer height, extrusion width, and nozzle temperature).
Additionally, experimental load testing was conducted to measure the actual deformation. Two design variants were tested: design A (thickness variation) and design B (arm width variation). The topology optimization showed a mass reduction of 65% and 30% for Design A and B, respectively. The static deformation simulation indicated that Design A performed better, with a maximum deformation of 0.227 mm compared with that of Design B, which was 1.583 mm.
Stiffness testing revealed 0.3355 mm deformation in Design A, which was evenly and symmetrically distributed, while Design B showed 0.3555 mm deformation with wider distribution in the central area. Experimental load testing showed 0.045 mm deformation under 100% load and 0.16 mm under 200% load, confirming that Sample 6 is structurally the most efficient and suitable for high-performance drone applications.
