Abstract

Access to adequate anatomical specimens can be an important aspect in learning the anatomy of domestic animals. In this study, the authors utilized a structured light scanner and fused deposition modeling (FDM) printer to produce highly accurate animal skeletal models. First, various components of the bovine skeleton, including the femur, the fifth rib, and the sixth cervical (C6) vertebra were used to produce digital models. These were then used to produce 1:1 scale physical models with the FDM printer. The anatomical features of the digital models and three-dimensional (3D) printed models were then compared with those of the original skeletal specimens. The results of this study demonstrated that both digital and physical scale models of animal skeletal components could be rapidly produced using 3D printing technology. In terms of accuracy between models and original specimens, the standard deviations of the femur and the fifth rib measurements were 0.0351 and 0.0572, respectively. All of the features except the nutrient foramina on the original bone specimens could be identified in the digital and 3D printed models. Moreover, the 3D printed models could serve as a viable alternative to original bone specimens when used in anatomy education, as determined from student surveys. This study demonstrated an important example of reproducing bone models to be used in anatomy education and veterinary clinical training.

摘要

获取足够的解剖标本对于学习家畜解剖学是一个重要的方面。在本研究中,作者使用结构光扫描仪和熔丝沉积建模(FDM)打印机来制作高度精确的动物骨骼模型。首先,使用牛的各种骨骼成分(包括股骨、第五肋骨和第六颈椎(C6))来制作数字模型。然后,使用 FDM 打印机将这些数字模型制成 1:1 比例的物理模型。然后将数字模型和三维(3D)打印模型的解剖特征与原始骨骼标本进行比较。研究结果表明,使用 3D 打印技术可以快速生产动物骨骼成分的数字和物理比例模型。在模型与原始标本之间的准确性方面,股骨和第五肋骨测量的标准偏差分别为 0.0351 和 0.0572。除了原始骨标本上的营养孔之外,所有特征都可以在数字和 3D 打印模型中识别出来。此外,根据学生的调查,3D 打印模型可用作解剖学教育中原始骨标本的可行替代品。本研究展示了一个重要的例子,即复制骨骼模型以用于解剖学教育和兽医临床培训。解剖科学教育 11:73-80。©2017 年美国解剖学家协会。
