Abstract

Purpose

Additive manufacturing requires a systemic approach to help industry on technology applicability research. Towards this end, the purpose of this research is to help manufacturing business leaders decide whether digitalised manufacturing based on additive manufacturing are suitable for engineering applications and help them plan technology transfer decisions.

Design/methodology/approach

The methodology is based on case study research and action research, involving a mix of quantitative and qualitative research methods. The empirical part involved the study of the fatigue life of industrial component manufactured by laser sintering as well as a combination of quantitative and qualitative methods to define a strategic decision-making.

Findings

Laser-sintered plastic materials are suitable in end use automotive applications, especially when there are multiple product variations. Fatigue life of the tested coupling meets the design requirements. Additionally, production of mechanical parts can be substituted by additive methods while digitalising the manufacturing process to gain productivity, especially when there is a need for mass-customisation.

Research limitations/implications

This research relies on a single case study research. The application used is unique and its technical empirical data cannot be transferred directly to other applications.

Practical implications

Industry practitioners can use this research to shed light on technology transferability challenges considering technical feasibility of additive polymer materials, economic aspects as well as strategic implications for implementing digitalised manufacturing methods based on additive manufacturing.

Originality/value

This research presents a combined study of technical and strategic factors for additive manufacturing transferability using an industrial mass-customisation case as an example. In addition, a new cost comparison model is presented including the impact of geometry variations.

Abstract

The promise of process integration between organizations too often is unfulfilled and new approaches are needed. Distributed control is a new and exciting opportunity to build more effective process networks for a wide range of applications in logistics and product development. A solution based on distributed control around the consumers of services in process networks is proposed. In logistics, it is the physical delivery that becomes the focus for distributed control when you approach the service environment from the consumer perspective. In collaborative design and manufacturing, it is the product model that becomes the focus of control. A consumer perspective provides key guidelines that help manufacturers and service providers identify the design of process networks that most efficiently add value in different industries and for different applications.

Abstract

Purpose

The purpose of this paper is to describe and evaluate the potential approaches to introduce rapid manufacturing (RM) in the spare parts supply chain.

Design/methodology/approach

Alternative conceptual designs for deploying RM technology in the spare parts supply chain were proposed. The potential benefits are illustrated for the aircraft industry. The general feasibility was discussed based on literature.

Findings

The potential supply chain benefits in terms of simultaneously improved service and reduced inventory makes the distributed deployment of RM very interesting for spare parts supply. However, considering the trade‐offs affecting deployment it is proposed that most feasible is centralized deployment by original equipment manufacturers (OEMs), or deployment close to the point of use by generalist service providers of RM.

Research limitations/implications

The limited part range that is currently possible to produce using the technology means that a RM‐based service supply chain is feasible only in very particular situations.

Practical implications

OEMs should include the consideration of RM in their long‐term service supply chain development.

Originality/value

The paper identifies two distinct approaches for deploying RM in the spare parts supply chain.

Abstract

Purpose

The purpose of this paper is to develop a workflow for 3D modeling and additive manufacturing (AM) of patient‐specific medical implants. The comprehensive workflow consists of four steps: medical imaging; 3D modelling; additive manufacturing; and clinical application. Implants are used to reconstruct bone damage or defects caused by trauma or disease. Traditionally, implants have been manually bent and shaped, either preoperatively or intraoperatively, with the help of anatomic solid models. The proposed workflow obviates the manual procedure and may result in more accurate and cost‐effective implants.

Design/methodology/approach

A patient‐specific implant was digitally designed to reconstruct a facial bone defect. Several test pieces were additive manufactured from stainless steel and titanium by direct metal laser sintering (DMLS) technology. An additive manufactured titanium EOS Titanium Ti64 ELI reconstruction plate was successfully implanted onto the patient's injured orbital wall.

Findings

This method enables exact fitting of implants to surrounding tissues. Creating implants before surgery improves accuracy, may reduce operation time and decrease patient morbidity, hence improving quality of surgery. By using AM methods it is possible to manufacture a volumetric net structure, which also allows cells and tissues to grow through it to and from surrounding tissues. The net is created from surface and its thickness and hole size are adjustable. The implant can be designed so that its mass is low and therefore sensitivity to hot and cold temperatures is reduced.

Originality/value

The paper describes a novel technique to create patient‐specific reconstruction implants for facial bony defects.

Abstract

Purpose

The main aim of this paper is to examine how commercial sustainability innovation projects in real estate and construction industries utilise the contemporary market‐oriented innovation models based on the service‐dominant logic.

Design/methodology/approach

A survey of a large set of sustainability innovation projects was conducted and analysed.

Findings

The results show that over a third of the examined projects lack all the necessary innovation components recognised in the literature. Furthermore, very few projects utilised concurrent market feedback in the development phase. The study suggests that sustainability innovations fail commercially in built environment, because they lack active customer participation and value network involvement, and they aim for incremental instead of radical improvements.

Research limitations/implications

Future research should address available ways for companies in the real estate and construction industries to take advantage of their unused potential in climate change mitigation business through innovation.

Practical implications

Organisations striving for sustainability innovations should aim at radical instead of incremental innovation, and focus on customer participation and involvement of the value network. The innovation processes in the construction sector could be organised better by utilising tested service‐dominant models.

Originality/value

This study is among the first to address innovation elements based on the service‐dominant logic in analysing projects aiming at sustainability innovation in real estate and construction industries.

Abstract

Purpose

The patient complaint is one of the main procedures of exercising patient’s rights in the Finnish health care system. Such complaints typically concern the quality of care and/or patient safety. The purpose of this paper is to examine the types of patient complaints received by a specialized medical care organization and the kinds of responses given by the organization’s personnel. The organization’s strategy and good governance principles provide the framework for understanding the organization’s action.

Design/methodology/approach

This study’s data comprise patient complaints and the responses from personnel of a specialized medical care organization from the start of 2012 to the end of January 2014. The data were analyzed through qualitative data analysis.

Findings

The results show many unwanted grievances, but also reveal the procedures employed to improve health care processes. The results are related to patients’ care experiences, provision of information, personnel’s professional skills and the approach to patient complaints handling. The integrative result of the analysis was to find consensus between the patients’ expectations and personnel’s evaluation of patients’ needs.

Originality/value

Few prior studies have examined patient complaints related to both strategy and good governance. Patient complaints were found to have several confluences with an organization’s strategic goals, objectives and good governance principles. The study recommends further research on personnel procedures for patient complaints handling, with a view to influencing strategic planning and implementation of strategies of organizations.
