Although 3D printing (3DP) technology has become an increasingly popular educational tool in recent years, very little is known about the learning benefits of this technology. This systematic literature review synthesized empirical research on learning with 3DP in various educational settings, focusing on publication and study participants' characteristics, curriculum areas, research methodologies, instructional approaches, educational outcomes and benefits. A comprehensive survey of published and unpublished studies identified 78 empirical studies that met the inclusion criteria. In addition to positive effects on learning, 3DP facilitated innovative curriculum development and created opportunities for cross-disciplinary research. The findings revealed five major trends in 3DP learning: (1) prepare a new generation of engineers, (2) democratize additive manufacturing technology and production, (3) support learning using low-cost 3D printed learning aids, (4) produce assistive technologies, and (5) promote creativity and innovation. The review identifies critical gaps in the literature and offers suggestions for future research.

3D打印技术学习实证研究的系统回顾

尽管 3D 打印 (3DP) 技术近年来已成为一种日益流行的教育工具，但人们对该技术的学习优势知之甚少。这篇系统的文献综述综合了在各种教育环境中使用 3DP 学习的实证研究，重点关注出版和研究参与者的特征、课程领域、研究方法、教学方法、教育成果和好处。对已发表和未发表研究的综合调查确定了 78 项符合纳入标准的实证研究。除了对学习产生积极影响外，3DP 还促进了创新课程的开发，并为跨学科研究创造了机会。调查结果揭示了 3DP 学习的五个主要趋势：（1）培养新一代工程师，(2) 使增材制造技术和生产大众化，(3) 使用低成本 3D 打印学习辅助工具支持学习，(4) 生产辅助技术，以及 (5) 促进创造力和创新。该评论确定了文献中的关键空白，并为未来的研究提供了建议。
