英文摘要:
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.

中文摘要:
在通知增材制造(AM)技术采用决策时,本文通过对包装行业中使用的复杂组件的制造成本进行工序间比较,研究了批量生产能力利用率与高效技术操作之间的关系。面对传统加工和焊接路径的报告成本,以及通过使用直接金属激光烧结(DMLS)的AM路径产生的成本估算,我们将四个方面结合在一起:优化的产能利用率、辅助工艺步骤、制造故障的影响和设计适配。认识到AM用户可以用其他可能不相关的几何图形填充未使用的机器容量,我们提出了“可替代”构建容量的特征。这方面通过计算构建体积包装,在一篮子样本几何图形上绘制,集成到成本估算框架中。我们表明,在满容量条件下,混合构建的单位成本低于仅限于单一类型几何体的构建;在我们的研究中,这导致平均单位成本多报了157%。AM采用后的估计制造成本节约从36%到46%不等。此外,我们指出,设计调整带来的运营成本节约可能远远超过制造成本优势。
