This paper builds on the authors' previous work with Augmented Reality (AR) technology as a tool to enhance traditional visualizations and facilitate the understanding of complex information. In this paper, we expand our previous work with AR technology by focusing on the process of creating custom content. Based on users' feedback, we describe and compare various strategies to create 3D models from real objects that can be subsequently integrated into augmented reality scenes. Specifically, we evaluate current 3D scanning technologies that are affordable and suitable for educational applications. We present a comparative analysis of low-cost 3D scanning technologies, its use, integration with AR, and implementation as educational tools. Factors considered in our study include portability, model size, resolution, and postproduction requirements.
