“…While customers may not be too concerned with the selection of manufacturer, the manufacturing location and lead time are often essential. The homogeneity of 3DP technology makes it possible to select manufacturers close to the end customer (Khajavi, Partanen, & Holmström, ), while at the same time, manufacturers with assembly operations are motivated to possess in‐house 3DP to reap the benefits of reduced handling, warehousing, and simplified assembly operations (Khajavi et al, ; Lyly‐Yrjänäinen, Holmström, Johansson, & Suomala, ). Thus, a 3DP company can be both a customer and a provider of 3DP services.…”

The direct‐from‐model and tool‐less manufacturing process of 3D printing (3DP) embodies a general‐purpose technology, facilitating capacity sharing and outsourcing. Starting from a case study of a 3DP company (Shapeways) and a new market entrant (Panalpina), we develop dynamic practices for partial outsourcing in build‐to‐model manufacturing. We propose a new outsourcing scheme, bidirectional partial outsourcing (BPO), where 3D printers share capacity by alternating between the role of outsourcer and subcontractor based on need. Coupled with order book smoothing (OBS), where orders are released gradually to production, this provides 3D printers with two distinct ways to manage demand variability. By combining demand and cost field data with an analytical model, we find that BPO improves 3DP cost efficiency and delivery performance as the number of 3DP firms in the network increases. OBS is sufficient for an established 3D printer when alternatives to in‐house manufacturing are few, or of limited capacity. Nevertheless, OBS comes at the cost of reduced responsiveness, whereas BPO shifts the cost and delivery performance frontier. Our analysis shows how BPO combined with OBS makes 3DP companies more resilient to downward movements in both demand and price levels.

“…Detailed information on these AM processes have been given in previous works, see for example Coykendall et al [2], Huang et al [3], and Koff and Gustafson [4]. Compared to conventional manufacturing processes, AM processes carry several significant advantages, such as material efficiency, resource efficiency, part flexibility, production flexibility [3,5] and direct kitting [6,7].…”

“…The need for agile manufacturing arises not only from rapidly changing market demand but also from novel design approaches exploring larger parts of the design space [1]. A potential manufacturing concept to address the need for agility is product-centric control, in which the digital counterpart of the product requests its own manufacturing services [3]. However, the research is specific to an industrial partner's business case of a single manufacturer serving several OEMs producing similar but customized products, and the focus is on the logistics level without investigating how the product-centric control can be applied to assembly planning.…”

This paper proposes a new concept in which a digital twin derived from a digital product description will automatically perform assembly planning and orchestrate the production resources in a manufacturing cell. Thus the manufacturing cell has generic services with minimal assumptions about what kind of product will be assembled, while the digital product description is designed collaboratively between the designer at an OEM and automated services at potential manufacturers. This has several advantages. Firstly, the resulting versatile manufacturing facility can handle a broad variety of products with minimal or no reconfiguration effort, so it can cost-effectively offer its services to a large number of OEMs. Secondly, a solution is presented to the problem of performing concurrent product design and assembly planning over the organizational boundary. Thirdly, the product design at the OEM is not constrained to the capabilities of specific manufacturing facilities. The concept is presented in general terms in UML and an implementation is provided in a 3D simulation environment using Automation Markup Language for digital product descriptions. Finally, two case studies are presented and applications in a real industrial context are discussed.
