Abstract

The use of 3D scanning technology has revolutionized paleontology by enabling the creation of precise digital fossil replicas. This non-invasive method reduces physical contact and allows for detailed analysis of complex structures. Our research used the Revopoint 3D scanner with RevoScan5 software, which required a learning curve. Initial scans of a replica of Michelangelo’s David helped refine techniques involving light, depth, and color, improving overall scan quality. In the lab, where conditions are controlled, the scanner performed adequately, producing high-quality models. However, fieldwork presented major challenges. Environmental variables—such as lighting, surface instability, and terrain—disrupted scans, and the scanner struggled with small or finely detailed fossils. It also failed to capture sufficient depth in permineralized specimens and showed color inaccuracies. Merging multiple scans was often problematic, requiring rescanning. These limitations directly impact the potential for 3D printing fossils for educational use. Since printing relies on high-quality scans, the scanner’s inability to capture fine detail and depth restricts what can actually be printed. While effective in controlled lab environments, the scanner is not yet reliable for field use. Nonetheless, it remains a cost-effective tool that promotes accessibility in research and STEM education, especially for institutions with limited resources.
