Three-Dimensional Modeling of Sheep Humerus by Photogrammetry

Abstract

The increasing use of three-dimensional models, one of the developing technologies in education, directs researchers to new studies in this field. The aim of this study is to create a low-cost model for the first time in long bones using the photogrammetry method and to contribute to the easy production of bones that are difficult to obtain in the future. In this study, images of sheep humerus were arranged and three-dimensional modeling was done in Cinema 4D software. The model, whose design was completed, was printed with a three-dimensional printer using Polylactic Acid (PLA) filament. In this study, for the first time, a three-dimensional model of the sheep humerus, which is a long bone, was created using the photogrammetry method, printed and compared with the real bone. It has been seen that anatomical structures can be designed and printed in the most realistic way, using only photographs, without the use of three-dimensional reconstruction devices. However, it has been observed that small artifacts occur on the contact surface between the PLA filament used for printing and support during the printing process. It was considered that this issue could be resolved in subsequent studies by using different support filaments during the printing of models.
