The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.

人体发育生物学教育的实际方面通常仅限于观察和使用动物模型来阐明发育解剖学。这在一定程度上是由于获取人类胚胎和胎儿标本的困难，以及将这些标本作为教学材料呈现的固有敏感性。本报告提出了一种新方法，即在实践课中使用实际人体材料的 3D 打印复制品，从而可以在教育环境中纳入准确的人类发育解剖学实例。一系列 3D 打印品是通过对存档的一系列保存的人类胚胎和胎儿标本进行计算机断层扫描 (CT) 成像收集的数字数据制作的。最终版本的 3D 打印品由多种单一或多种材料生成，以说明人体发育的进展，包括内部解剖结构的发育。此外，为了进行大班教学，每种复制品都打印了多个副本。除了检查准确的 3D 复制品的教育益处外，这种方法还减少了学生对观察实际人类胚胎/胎儿解剖标本产生不良反应的可能性（由于文化背景或个人经历），并降低了原始标本损坏或丢失的可能性。这种方法结合了数字数据管理和分析以及扫描技术的不断改进，使胚胎学学生能够访问本地和国际人类妊娠材料收藏。解剖科学教育 00: 000-000. © 2018 美国解剖学家协会。
