To review the basics of 3-D printing and discuss the future of 3-D printing and its place in medical imaging.
A literature search was conducted using EBSCO, JSTOR, ProQuest, and Google Scholar. Recent publications that provided robust and current information were preferred, but older articles were used, if needed.
3-D printing began by converting a computer-aided design into a physical model. Also referred to as additive manufacturing, 3-D printing was developed as an alternative to the more costly process of subtractive manufacturing. The construction, application, and implementation of 3-D product designs has allowed for 3-D printing in various environments, from manufacturing to medicine.
Since its beginning, the purpose and applicability of 3-D printing have shifted from the simple production of visual prototypes to the provision of innovative solutions to problems. 3-D printing has allowed for greater creativity in medicine and is increasing the popularity of medical imaging because of its suitability for anatomic modeling, teaching, and patient education.
Radiology departments are becoming vital components of 3-D printing in health care by providing computed tomography or magnetic resonance imaging data sets to designate anatomical structures for 3-D fabrication. 3-D medical printing programs in hospital settings might be limited to larger facilities because of associated start-up costs. However, as competition in the 3-D market increases, costs are expected to decline, which will help reduce barriers to 3-D printing across the health care community.
回顾 3D 打印的基础知识，并讨论 3D 打印的未来及其在医学成像中的地位。
通过 EBSCO、JSTOR、ProQuest 和 Google Scholar 进行文献检索。首选提供可靠和最新信息的近期出版物，但如果需要，也会使用较旧的文章。
3D 打印始于将计算机辅助设计转化为物理模型。也称为增材制造，3D 打印是作为成本更高的减法制造工艺的替代方法而开发的。3D 产品设计的构建、应用和实施使得 3D 打印能够在从制造到医学等各种环境中使用。
自成立以来，3D 打印的目的和适用性已经从简单的视觉原型生产转变为提供创新的问题解决方案。3D 打印使医学领域更具创造力，并因其适用于解剖模型、教学和患者教育而提高了医学成像的普及度。
放射科通过提供计算机断层扫描或磁共振成像数据集来指定 3D 制造的解剖结构，成为医疗保健中 3D 打印的重要组成部分。由于与启动成本相关，医院环境中的 3D 医疗打印计划可能仅限于较大的设施。然而，随着 3D 市场竞争的加剧，成本预计会下降，这将有助于降低医疗保健界 3D 打印的障碍。
