3D Scanner Using Arduino

Advancements in accessible electronics and open-source platforms have enabled the development of affordable 3D scanning technologies for diverse applications. This paper presents a robust, low-cost 3D object scanning system that integrates Arduino microcontrollers, infrared sensors, and stepper motors. By automating the rotational capture of an object and recording surface distances via infrared sensing, the system generates a precise 3D point cloud. The collected data is processed using open-source software for mesh reconstruction and visualization. Designed to democratize 3D scanning capabilities, this prototype delivers reliable and accurate scans for small to medium-sized objects. Through careful calibration and testing under varied lighting and surface conditions, the system achieves consistent performance, offering a practical, DIY alternative to expensive commercial scanners. This work underscores the potential of open-source hardware and software integration in expanding access to digital fabrication and reverse engineering technologies.
