Low-Cost 3D Scanning Machine Using ESP32 and IR Sensor

Abstract

The design and development of a low-cost 3D scanning machine using an ESP32 microcontroller and an infrared (IR) distance sensor. The system uses a rotating platform and vertical sensor movement to capture object geometry from multiple angles. Distance measurements are recorded and stored in digital format for further processing. The collected data is converted into a 3D point cloud and reconstructed into a mesh model using open-source software. The proposed system offers a simple, affordable, and efficient solution for basic 3D scanning applications. It can be used in areas such as reverse engineering, rapid prototyping, and education. The results demonstrate that reliable 3D models can be generated using low-cost components with acceptable accuracy.
