Purpose

Although additive manufacturing (AM) has been demonstrated to have significant potential in improving spare part delivery operations and has been adopted to a degree in the aviation and automotive industries, its use in spare part production is still limited in other fields due to a variety of implementation barriers. The purpose of this article is to assess the significance of previously reported barriers in the context of the machine-building industry.

Design/methodology/approach

Adoption barriers are identified from the literature and formulated as hypotheses, which are verified with a set of focus group interviews consisting of original equipment manufacturers (OEMs), AM service providers and quality inspection and insurance institutions. The results of the interviews are reported qualitatively, and the transcripts of the interviews are subjected to quantitative content analysis.

Findings

The article identifies distrust in quality, insufficient material and design knowledge among stakeholders and poor availability of design documentation on spare parts as the key barriers of adopting AM in the production of spare parts. The three key barriers are interconnected and training engineers to be proficient in design and material issues as well as producing high-quality design documentation will yield the highest increase in AM implementation in spare parts.

Originality/value

The article offers a unique approach as it investigates the subjective views of a cross-organizational group of industrial actors involved in the machine-building industry. The article contributes to the theory of digital spare parts by verifying and rejecting presented barriers of AM implementation and how they are interconnected.

评估机械制造行业中制造增材制造数字零件的行业壁垒：跨组织焦点小组访谈研究

目的

尽管增材制造（AM）已被证明在改善备件交付操作方面具有巨大潜力，并且已在航空和汽车行业得到一定程度的采用，但由于其他各种原因，其在备件生产中的使用仍然受到其他领域的限制。实施障碍。本文的目的是评估在机械制造行业中先前报告的障碍的重要性。

设计/方法/方法

从文献中可以识别采用障碍，并将其表述为假设，并通过一组由原始设备制造商（OEM），增材制造服务提供商以及质量检查和保险机构组成的焦点小组访谈进行验证。定性报告访谈结果，并对访谈笔录进行定量内容分析。

发现

该文章指出，对质量的不信任，利益相关者之间的材料和设计知识不足以及零件设计文档的可用性不足是在零件生产中采用AM的主要障碍。这三个主要障碍是相互联系的，培训工程师精通设计和材料问题以及生成高质量的设计文档，将使备件中AM实施的增加最大。

创意/价值

本文提供了一种独特的方法，因为它调查了涉及机械制造行业的跨组织工业参与者群体的主观观点。本文通过验证和拒绝AM实施的障碍以及它们之间的相互联系，为数字备件理论做出了贡献。
