Abstract [en]

This paper is focused on automotive stamping tools and dies as well as the impact of 3D metal printing and metals related 3D-printing on design and production of such tools and dies. The purpose has been to find out the current industrial potential of 3D-printing as far as lead time, costs, shapes, material usage, metal piece size, surface roughness, hardness, strength, and machinability are concerned. The business transformational impact of 3D-printing is also addressed in this paper. The obtained results show that the lead time can be halved, the costs are somewhat higher, and the strength, hardness, surface roughness, and machinability of the 3D-printed metallic tools and dies are as good as those of the conventionally made. The maximum size of a metal piece that can be 3D-printed today by Powder Bed Fusion (PBF) is, in the best case, 500 mm × 500 mm × 500 mm. 3D-printing can also be used for the pattern to make the mold box in iron and steel casting. It is also possible to eliminate the casting pattern, since the mold box can be 3D-printed directly. All this has started to have a large business impact, and it is therefore of great significance to outline and execute an action plan almost immediately.

Abstract [en]

Purpose: With the overarching idea of disruptive technology and its effects on business, this paper focuses on how companies strategically consider meeting the challenge of a disruptive technology such as additive manufacturing. The purpose of this paper is to describe and discuss changes in positions and roles related to the implementation of a disruptive technology.

Design/methodology/approach: Additive manufacturing could be expected to have different consequences for parties based on their current supply chain positions. The paper therefore investigates companies' strategies related to various supply chain positions and does so by departing from a position and role point of view. Three business cases related to metal 3D printing - illustrating sub-suppliers, manufacturers and logistics firms - describe as many strategies. Data for the cases were collected through meetings, interviews, seminars and secondary data focusing on both current business activities related to additive manufacturing and scenarios for the future.

Findings: The companies attempted to defend their current positions, leading to new roles for them. This disconnects the change of roles from that of positions. The changed roles indicate that all parties, regardless of supply chain positions, would move into competing producing roles, thereby indicating how a disruptive technology may disrupt network structures based on companies' attempts to defend their positions.

Originality/value: The paper contributes to previous research by reporting a disconnect between positions and roles among firms when disruption takes place. The paper further denotes how the investigated firms largely disregarded network consequences at the disruptive stage, caused by the introduction of additive manufacturing. The paper also contributes to research on additive manufacturing by including a business dimension and linking this to positions and roles.

Abstract [en]

Additive manufacturing, that is 3D printing technology, may change the way companies operate their businesses. This article adopts a business model perspective to create an understanding of what we know about these changes. It summarizes current knowledge on additive manufacturing within management and business research, and it discusses future research directions in relation to business models for additive manufacturing. Using the scientific database Web of Science, 116 journal articles were identified. The literature review reveals that most research concerns manufacturing optimization. A more holistic view of the changes that additive manufacturing may bring about for firms is needed, as is more research on changed value propositions, and customer/sales-related issues. The article contributes to previous research by systematically summarizing additive manufacturing research in the business and management literature, and by highlighting areas for further investigation related to the business models of individual firms.

Abstract [en]

IMP research is often treated as an empirical perspective describing complexities of repeated business-to-business exchanges and their embeddedness. While building on some common understandings and concepts, this paper asks: How homogeneous is the IMP research? This paper uses cluster analysis to capture the roots and various sub-groups of IMP research as means to depict the question of homogeneity (i.e. a core focus in the research) or heterogeneity (i.e. using references from other fields or specific to sub-fields) of the IMP thought. In this scientific work in progress paper we introduce how we design to use bibliographical methods in order to harvest data from an extensive amount of IMP-related articles written from the 1970’s onwards. In this first attempt to reveal IMP we used overall 294 articles yielded to 10,615 co-citation relationships. A threshold of minimum number of citations of a cited reference was set to five (5) to capture such references that have been cited in multiple publications. We introduce visual mapping of defined subject area clusters and as an example we describe shortly clusters. Perhaps not surprisingly our findings suggest that IMP research is not so homogenous, with at least four clear clusters of IMP-research each utilizing different key references.
