AI Technical Summary
Technical Problem
Existing tie rods used in applications such as aircrafts are heavy and costly due to their traditional manufacturing methods and materials, which limits their ability to provide both high tensile strength and light weight.
Method used
The development of 3D printed tie rods using continuous fibers and variable density infill, which provides high tensile strength and light weight, while also allowing for adjustable or fixed lengths depending on the application.
Benefits of technology
The 3D printed tie rods achieve a significant weight reduction of up to 75% compared to traditional tie rods, while maintaining or exceeding their tensile strength, thus offering substantial weight benefits and cost-effectiveness in applications like aircrafts.

Abstract
A tie rod can include an elongated shaft, and one or more eyes, where continuous fibers extend from the shaft to the one or more eyes. The shaft can include a set of continuous fibers, made of a first material, extending continuously along a length of the elongated shaft, and a variable density infill disposed in at least a portion of the elongate shaft. The variable density infill formed of a second material, the variable density infill having a variable density at least along the length of the elongated shaft. An eye can extend from a first end portion of the elongated shaft and include a curved portion. One or more continuous fibers of the set of continuous fibers extend continuously along the curved portion of the eye.
