The Impact of Low-Fidelity Three-Dimensional-Printed Models of the Equine Distal Limb and the Canine Forelimb in Teaching Veterinary Anatomy in Practical Classes

Limited cadaver availability and health risks from formaldehyde-treated cadavers have increased the need for alternative learning materials in veterinary anatomy education. Two studies were conducted to investigate whether low-fidelity 3D-printed models provide comparable learning outcomes to real specimens. In study 1, veterinary students were assigned to two groups to study the equine distal limb on a real specimen (<i>n</i> = 67) or a 3D model (<i>n</i> = 68). In study 2, students were divided into four groups to study the canine forelimb on a real specimen (<i>n</i> = 44), a 3D model (<i>n</i> = 45), a 3D model followed by a real specimen (<i>n</i> = 47), or the reverse combination (<i>n</i> = 47). Learning outcomes were measured through a knowledge assessment. Afterwards, learning materials were evaluated by students. Both studies showed significantly higher learning outcomes in the groups learning with real specimens compared to other test groups. While students preferred to start learning with 3D models before switching to real specimens, this method had the lowest learning outcomes. However, students emphasized the value of 3D models for independent learning outside the dissection hall and desired further 3D models of other anatomical specimens. Findings indicated that low-fidelity 3D-printed models cannot replace real specimens but are a useful complementary tool in veterinary anatomy education.
