Design and Development of 3D Wire Bending Machine

ABSTRACT— This project focuses on designing and developing an automated 3D wire bending machine utilizing an Arduino microcontroller for precise control. Traditional wire bending processes, often manual, suffer from inconsistencies, errors, and low efficiency, which affects product quality and increases production time. To address these challenges, the proposed machine integrates CNC-type control to enable accurate and repeatable bending of wire into complex three-dimensional shapes. The machine design involves CAD modelling of components, 3D printing of gears and parts, and assembly of mechanical and electronic systems. By programming the Arduino controller, the machine controls wire feeding, straightening, and bending operations with high accuracy while minimizing human intervention. Testing demonstrated the prototype’s ability to bend wires into desired shapes with improved precision and faster operation, offering a low-cost, flexible solution for industries requiring customized wire bending. This development not only reduces dependency on skilled manual operators but also enhances productivity and product quality in wire bending applications. If a more specific style or detail level is needed, that can be provided as well. This abstract is synthesized based on project report sources describing similar 3D wire bending machines using Arduino and automation principles.
