由于添加制造(AM)过程的复杂性和变化性，存在一定程度的不确定性，从而在质量保证(QA)中产生关键问题，必须通过耗时和成本密集型任务来解决。这降低了工艺的重复性、可靠性和部分再现性。到目前为止，AM的许多工作都是在几十年内以孤立和分散的方式执行的。本文提出了一种系统集成的整体视图来实现AM的质量保证，并提出了一种系统集成的视图来确保在AM过程之前/过程中/之后的预定义的零件属性。它包括四个阶段，即质量保证计划、前瞻性验证、并行验证和追溯验证。作为质量保证计划的基础，利用功能设计模型ICAM Definition for Function Model提出了QA计划的功能工作流程和所需的信息流。QA计划的功能设计模型提供了系统集成的视图，可作为检查AM过程的重复性和AM部件的再现性的基础。最后，通过粉末床融合过程验证了该QA计划的可行性。在许多假设下证明了可行性；本研究不包括真正的验证。本研究提供了一种创新和变革性的方法，可以提高跨行业AM部件的生产率和质量。此外，QA指南和功能设计模型为开发QA架构和管理系统提供了基础。这种系统集成的观点和相应的QA计划可以向AM社区提出基本问题，并在AM过程和部件的现场数字检测方面启动新的研究努力。
Due to the complexity of and variations in additive manufacturing (AM) processes, there is a level of uncertainty that creates critical issues in quality assurance (QA), which must be addressed by time-consuming and cost-intensive tasks. This deteriorates the process repeatability, reliability and part reproducibility. So far, many AM efforts have been performed in an isolated and scattered way over several decades. In this paper, a systematically integrated holistic view is proposed to achieve QA for AM.,A systematically integrated view is presented to ensure the predefined part properties before/during/after the AM process. It consists of four stages, namely, QA plan, prospective validation, concurrent validation and retrospective validation. As a foundation for QA planning, a functional workflow and the required information flows are proposed by using functional design models: Icam DEFinition for Function Modeling.,The functional design model of the QA plan provides the systematically integrated view that can be the basis for inspection of AM processes for the repeatability and qualification of AM parts for reproducibility.,A powder bed fusion process was used to validate the feasibility of this QA plan. Feasibility was demonstrated under many assumptions; real validation is not included in this study.,This study provides an innovative and transformative methodology that can lead to greater productivity and improved quality of AM parts across industries. Furthermore, the QA guidelines and functional design models provide the foundation for the development of a QA architecture and management system.,This systematically integrated view and the corresponding QA plan can pose fundamental questions to the AM community and initiate new research efforts in the in-situ digital inspection of AM processes and parts.
