YouTube channel How To Mechatronics has created a great tutorial with full instructions on how to create your very own Arduino powered 3D wire bending machine. Created using 3D printer parts, a handful of stepper motors, and an Arduino Nano development board, the wire bending machine can be programmed to create a wide variety of different shapes and angles.
Components and Assembly
The core components of this project include 3D printer parts, stepper motors, and an Arduino Nano development board. The stepper motors are crucial as they provide the precise control needed to bend the wire into intricate shapes. The 3D printer parts are used to construct the frame and various mechanical components of the machine. The Arduino Nano serves as the brain of the operation, executing the code that dictates the machine’s movements.
In addition to these primary components, you will also need a wire straightener, a feeder, and a z-axis mechanism. The wire straightener ensures that the wire is perfectly straight before it enters the bending mechanism. The feeder controls the length of the wire that is fed into the machine, and the z-axis mechanism allows for vertical movements, adding another dimension to the shapes that can be created.
Programming and Functionality
The programming aspect of this project is handled through the Arduino IDE. The tutorial provides detailed instructions on how to write and upload the code to the Arduino Nano. The code includes custom functions for creating various shapes such as stars, cubes, and simple stands. There is also a manual mode that allows users to input commands through the serial monitor, offering greater flexibility in creating custom wire forms.
Watch the demonstration video below to learn more about the Arduino wire bending machine, which is equipped with a straightener, feeder, and z-axis. “In this tutorial, I will show you how I built an Arduino-based 3D wire bending machine. This is actually a typical mechatronic system because it involves mechanical, electrical, and computer engineering. Therefore, I believe many engineering students or anyone who is new to mechatronics will find this project interesting. I made a few custom functions for making various shapes, like a star, a cube, and a simple stand, as well as a manual mode where we can make the wire forms by entering commands through the serial monitor.”

Applications and Future Improvements
The potential applications for a 3D wire bending machine are vast. It can be used in various fields such as art, engineering, and manufacturing. Artists can use it to create intricate wire sculptures, while engineers can use it to prototype parts or create custom tools. In manufacturing, such a machine can be used to produce components for electronics, automotive parts, and more.
Future improvements to this project could include adding more axes for even greater flexibility in wire bending. Another enhancement could be the integration of a graphical user interface (GUI) to make the machine more user-friendly. Additionally, incorporating sensors to provide real-time feedback could improve the accuracy and reliability of the wire bending process.
