Aurochs vs. Cattle – Cranium Comparison
We were particularly pleased by the scans of two large cattle craniums made with the Artec Eva scanner.
Since the scanner is particularly accurate to produce 3D models, we were able to compare scans side by side to display differences in shape and size.
The project was carried out by Atticus Pinzon Rodriguez.
Our zoology course comprises several practical sessions, where the students study diverse groups within the animal kingdom. Among the models and specimens used, there are several items that are more than 100 years old, which makes them unique and not ideal for constant manipulation by the students.
To make more sturdy models, the wax models of echinoderm larvae were 3D scanned by a CT (computer tomograph) scanner. The produced files were corrected and converted to 3D printer friendly files. Noise, blobs and other artefacts were cut away and irregularities fixed. The cleaned models were then made hollow to produce an empty model suitable for printing.
The models were printed in a Selective Laser Sintering machine, on white nylon powder; and coated by a layer of matt finishing varnish, for protection.
