A tale of two whales: applying digital imaging and 3D printing to cetacean research and education

Abstract

Emerging technologies are changing how scientists and the public see and interact with cetacean specimens. As staff at a small, rural, marine science center, we employed LIDAR (light detection and ranging), x‐ray, computational tomography, and structured light scanning along with three‐dimensional (3D) printing to study and exhibit the remains of a 7.9‐m transient male killer whale (Orcinus orca) and a 22.4‐m female blue whale (Balaenoptera musculus). In collaboration with larger institutions, we applied these technologies to bone replication, skeletal articulation, soft‐tissue anatomical studies, and digital modeling to create high‐quality specimen replicas. These techniques surpass traditional modeling and restoration methods, and advance specimen‐associated research and documentation. In addition, 3D technology supports education and public awareness through in‐person and online exhibits and demonstrations. The decreasing cost and increasing appeal of advanced imaging can be used to enhance community engagement and the accessibility of science.
