Advanced visualization firm TeraRecon and 3D printing firm WhiteClouds have created a fan-like 3D-printed model based on CT scans of an ailing rhinoceros.
A resident at Brookfield Zoo in Chicago, Layla is a 7-year-old, 2,300-lb eastern black rhinoceros that underwent CT scanning after getting a sinus infection due to an impacted molar tooth, according to statement by TeraRecon.

Printing with this method enabled the surgeons to open up the 3D-printed model and visualize targeted areas, which, in turn, helped them plan two surgeries to remove the impacted tooth and infected tissue.

The CT image is shown in the axial plane. The PMV is automatically extracted using the developed deep learning model and overlayed onto the lungs for visual clarity.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/03/genkin.25LqljVF0y.jpg?auto=format%2Ccompress&crop=focalpoint&dpr=2&fit=crop&h=167&q=70&w=250)
