This study proposes a decision support model to explore the effect of supply chain collaboration on the existing barriers to implementing additive manufacturing in manufacturing supply chains. Based on data from Nigerian manufacturing companies, this study determined the severity of the barriers to implementing additive manufacturing in supply chains and then analyzed the impact of supply chain collaboration initiatives on the investigated barriers. The results indicate that barriers related to the technological category are the most severe as well as pinpoint the systemic relationships among the investigated barriers and determine the supply chain collaboration initiatives that are strongly impacting on the barriers. Furthermore, the study results illustrate that the structural barriers that exhibit the highest sense of priority are lack of infrastructural support, insufficient top management support, inadequate government support, low relative advantage and absence of competitive pressure. Hence, this article presents reliable guidelines to manufacturing firms to be aware of the barriers and ensure the development of proper strategies for successful additive manufacturing project outcomes.

本研究提出了一个决策支持模型，以探索供应链协作对在制造供应链中实施增材制造的现有障碍的影响。根据尼日利亚制造公司的数据，本研究确定了在供应链中实施增材制造的障碍的严重程度，然后分析了供应链协作计划对所调查障碍的影响。结果表明，与技术类别相关的障碍最为严重，并指出了所调查障碍之间的系统关系，并确定了对障碍有强烈影响的供应链协作计划。此外，研究结果表明，表现出最高优先感的结构性障碍是缺乏基础设施支持、高层管理支持不足、政府支持不足、相对优势低和缺乏竞争压力。因此，本文为制造公司提供了可靠的指导方针，以了解障碍并确保制定适当的策略以取得成功的增材制造项目成果。
