Description
Summary:Three‐dimensional (3D) printing technology is a rapid prototyping method that has recently been increasingly used in anatomy education. Magnetic resonance imaging, computed tomography, and 3D scanners are generally used to create 3D models. The aim of this study, which was performed without using the aforementioned devices, is to design sheep scapula models in a computer environment and compare bone models created with different filaments printed by a 3D printer with real bone. Photographs of sheep scapula were taken for modelling, and measurements were made from certain points. After the photographs were transferred to a computer environment, they were transformed into 3D using the Cinema 4D software, a computer‐aided design program. Models were created using a 3D printer employing polylactic acid (PLA) and thermoplastic polyurethane (TPU) filaments. By comparing the models created with PLA and TPU filaments to the real bone, it was found that they have a similar anatomical structure, with dimensional‐morphometric differences found at some points. It was also observed that the scapula model created with PLA filaments was more resistant to impacts than the real bone and that the model created with TPU filaments was more flexible, with very low fragility as compared to PLA and real bone. Therefore, this method allows obtaining a large number of durable models as an alternative to the real bone without the need for much manpower or equipment and without the need for a 3D reconstruction device.
