Abstract
Cadaver bones and artificial bones are utilized to perform preoperative studies and education purposes. Cadaver bones are hard to find, require ethical permissions, and have infection hazards. Therefore, commercial artificial bones are preferred in practice. Nonetheless, since these commercial alternatives are standardly produced in an average size and geometry, it is almost impossible to adapt them to a specific surgical simulation. In addition, these artificial bones have relatively high costs, which limits their accessibility. On the other hand, ColorJet printing (CJP), one of the three-dimensional printing technologies, offers a rapid and cost-effective alternative. However, whether the printed 3D-printed models can mechanically comply with artificial bones is unclear. In this study, 3D-printed bones and artificial commercial composite bones were compared in terms of mechanical properties. Compression tests were applied over 14 printed and 14 composite bones using the ISO 5833 standard. Mechanical properties including stress-strain, load to failure, and elastic modulus were calculated, and these results were compared using the two-sample independent t-test, which is one of the statistical analysis methods. Consequently, there was no significant difference between the bone models in terms of stress and failure load values (p
