标题： Informing Additive Manufacturing technology adoption: total cost and the impact of capacity utilisation

摘要： 在告知增材制造（AM）技术采用决策方面，本文研究了在包装行业用于复杂部件制造的工艺间比较中，构建体积容量利用率与高效技术运行之间的关系。 将传统机械加工和焊接路径的报告成本与通过使用直接金属激光烧结（DMLS）的AM路线产生的成本估算进行对比，我们综合了四个方面：优化的容量利用率、辅助工艺步骤、构建失败的影响以及设计适应性。 认识到AM用户可以利用其他潜在不相关的几何形状来填充未使用的机器容量，我们提出了一种“可替代”的构建容量特性。 这一方面通过计算构建体积打包整合到成本估算框架中，借鉴了一组样本几何形状。 我们表明，在满容量的混合构建中，单位成本低于仅限于一种几何形状的构建；在我们的研究中，这导致单位成本平均高估了157%。 从AM采用中估计的制造成本节约范围为36%至46%。 此外，我们指出，由于设计适应性带来的运营成本节约可能远超过制造成本优势。 显示英文摘要

摘要： Informing Additive Manufacturing (AM) technology adoption decisions, this paper investigates the relationship between build volume capacity utilisation and efficient technology operation in an inter-process comparison of the costs of manufacturing a complex component used in the packaging industry. Confronting the reported costs of a conventional machining and welding pathway with an estimator of the costs incurred through an AM route utilising Direct Metal Laser Sintering (DMLS), we weave together four aspects: optimised capacity utilisation, ancillary process steps, the effect of build failure, and design adaptation. Recognising that AM users can fill unused machine capacity with other, potentially unrelated, geometries, we posit a characteristic of 'fungible' build capacity. This aspect is integrated in the cost estimation framework through computational build volume packing, drawing on a basket of sample geometries. We show that the unit cost in mixed builds at full capacity is lower than in builds limited to a single type of geometry; in our study this results in a mean unit cost overstatement of 157%. The estimated manufacturing costs savings from AM adoption range from 36% to 46%. Additionally, we indicate that operating cost savings resulting from design adaptation are likely to far outweigh the manufacturing cost advantage.
