To review the elements of the vat-polymerization workflow, including the 3D printing parameters, support structures, slicing, and post-processing procedures, as well as how these elements affect the characteristics of the manufactured dental devices.
Collection of published articles related to vat-polymerization technologies including manufacturing workflow description, and printing parameters definition and evaluation of its influence on the mechanical properties of vat-polymerized dental devices was performed.
Three search engines were selected namely Medline/PubMed, EBSCO, and Cochrane. A manual search was also conducted.
The selection of the optimal printing and supporting parameters, slicing, and post-processing procedures based on dental application is in continuous improvement. As well as their influence on the characteristics of the additively manufactured (AM) devices such as surface roughness, printing accuracy, and mechanical properties of the dental device.
The accuracy and properties of the AM dental devices are influenced by the technology, printer, and material selected. The printing parameters, printing structures, slicing methods, and the post-processing techniques significantly influence on the surface roughness, printing accuracy, and mechanical properties of the manufactured dental device; yet, the optimization of each one may vary depending on the clinical application of the additively manufactured device.
The printing parameters, supporting structures, slicing, and post-processing procedures have been identified, but additional studies are needed to establish the optimal manufacturing protocol and enhance the properties of the AM polymer dental devices.
The understanding of the factors involved in the additive manufacturing workflow leads to a printing success and better outcome of the additively manufactured dental device.
回顾 vat 聚合工作流程的要素，包括 3D 打印参数、支撑结构、切片和后处理程序，以及这些要素如何影响制造的牙科设备的特性。
收集了与 vat 聚合技术相关的已发表文章，包括制造工作流程描述以及打印参数定义，并评估了其对 vat 聚合牙科设备机械性能的影响。
选择了三个搜索引擎，即 Medline/PubMed、EBSCO 和 Cochrane，并进行了手动搜索。
基于牙科应用，最佳打印和支撑参数、切片和后处理程序的选择仍在不断改进。以及它们对增材制造（AM）设备特性的影响，如表面粗糙度、打印精度和牙科设备的机械性能。
AM 牙科设备的准确性和性能受所选技术、打印机和材料的影响。打印参数、打印结构、切片方法和后处理技术对制造牙科设备的表面粗糙度、打印精度和机械性能有显著影响；然而，每个参数的优化可能因增材制造设备的临床应用而异。
已确定打印参数、支撑结构、切片和后处理程序，但需要进一步研究以确定最佳制造协议并提高 AM 聚合物牙科设备的性能。
了解增材制造工作流程中涉及的因素可实现打印成功并改善增材制造牙科设备的结果。
