“…While in conventional manufacturing-based supply chains the majority of the cost of a component is traced back to logistical costs; the bulk of the cost of an additively manufactured component is direct manufacturing costs [17]. Additionally, there have been approaches to investigate the technical aspects of distributed AM, describing potential positive effects between AM and cyber-physical production systems [18].…”

Additive manufacturing of digital spare parts offers promising new possibilities for companies to drastically shorten lead times and to omit storage costs. However, the concept of digital spare parts has not yet gained much footing in the manufacturing industry. This study aims to identify grounds for its selective rejection. Conducted from a corporate perspective, outlining a holistic supply chain network structure to visualize different digital spare part distribution scenarios, this survey study evaluates technical and economic additive manufacturing capabilities. Results are analyzed and discussed further by applying the Mann-Whitney test to examine the influence of the company size and the presence of 3D-printed end-use components within supply networks on gathered data. Machines’ limited build chamber volumes and the necessity of post-processing are considered as the main technical challenges of current additive manufacturing processes. Furthermore, it can be concluded that company sizes have a significant effect on perceived technological limitations. Overall, the results lead to the conclusion that the readiness level of the digital spare parts concept demands for further development.

“…Regarding the application of AM for the decentralization of production activities, Khajavi and colleagues present a technical evaluation of the potential impact of introducing AM within a supplychain configuration for spare parts (Khajavi et al 2014). Some approaches exist to evaluate technically and economically the effect of applying AM to decentralize manufacturing activities (Durão et al 2016;Khajavi et al 2014). However, no comprehensive study trying to assess the environmental impacts of a product manufactured in a decentralized manufacturing system employing AM compared to its centralized counterpart exits.…”

SummaryMotivated by the rising costs of doing business overseas and the rise and implementation of digital technologies in production, new strategies are being explored to bring production and demand closer. While concepts like cloud computing, internet of things, and digital manufacturing increasingly gain relevance within the production activities of manufacturing companies, significant advances in three-dimensional (3D) printing technologies offer the possibility for companies to accelerate product development and to consider new supply chain models. Under this production scheme, material supply chains are redefined and energy consumption hotspots are relocated throughout the life cycle of a product. This implies a diversification of energy mixes and raw material sources that poses a risk of shifting problems between life cycle phases and areas of protection. This study compares a conventional mass scale centralized manufacturing system against a 3D printing-supported distributed manufacturing system on the basis of the production of one frame for eyeglasses using the life cycle assessment methodology. The study indicates clearly that the optimization potential is concentrated mainly in the energy consumption at the unit process level and exposes a close link to the printing material employed.

“…In this chapter we look at the quantification of the feasibility and the economics of additive manufacturing from the point of view of spare parts manufacturing that is we use it as the underlying context. The production of spare parts for technically high-end industries such as the automotive and the aerospace industry [8][9][10][11] is something that has already been found economically viable, therefore it constitutes a good ground for quantitative illustrations. Spare parts manufacturing is interesting also from the point of view that the spare parts business has some distinct characteristics, which make it fit especially well with additive manufacturing: there is a need for reducing lead times, for minimizing the supplier's inventory [12], and there is also the issue of extending the time original equipment manufacturers (OEM) are able to offer spare parts support [13,14].…”

In the literature there is a lot of talk about the economics of additive manufacturing—typically the terminology used is imprecise at best, and attempts to quantify the benefits from additive manufacturing are most often based on single case studies. This chapter sets out to create a more general picture of the overall economics and feasibility of using additive manufacturing by using a simulation model. The simulation optimizes the cost of production and the end result is information on how often and where in the production lifetime additive manufacturing is the cost optimizing choice. This information is compared to literature-based production strategies envisioned for additive manufacturing. The context of this model and the chapter is that of spare parts production, however, the results resonate beyond this context. The results presented are illustrative and widen the understanding of where during the production-cycle additive manufacturing is economically feasible.
