3-D Printed Structural Elements And Their Modeling For Aerospace Usage

Abstract

This research aims to analyze how of the commonly used 3D printing filaments provided by the MakerSpace Lab to students, who partake in aerospace competitions, when varying infill density and printing orientation, and compared to traditionally used materials like wood, perform when subjected to tensile tests. After undergoing the tests, the specimens made from PLA, PETG, and Nylon of 50% and 20% infill densities and printed in both flat and side orientations showed that PLA of 50% infill density had the highest yield among the filaments. Filaments surpassed the Young’s modulus of Basswood but not Balsawood. Out of all the filaments, Nylon proved to be the most elastic.
