Abstract

Purpose

This paper aims to present a pilot study’s aims to identify opportunities and limits deriving from the use of low-cost 3D printing (3DP), fused deposition modelling (FDM), open-source technologies in co-design and co-production processes involving persons with rheumatic diseases (RDs).

Design/methodology/approach

In the paper, the authors outline why the use of low-cost, entry-level FDM can be meaningful for this scenario, implying a complete sharing of the design and the production phases of small assistive devices. The +TUO process is composed of several stages, among which the generative session represents the core.

Findings

This study highlights as the introduction of this low-cost technology in co-generative processes with people with RDs is a real challenge that can lead to new products and solutions, and that can sustain a social and local manufacturing approach for people facing a specific disablement.

Research limitations/implications

This research is a first step of a broader research, new researches are going to explore further details related with the technology and of the adopted method.

Practical implications

Involving actively, the end user during the creation process can bring advantages such as meeting more precisely their needs and create innovative products, as shown in the text.

Social implications

For people living with RDs, an occupation is important to sustain a process of empowerment. Adopting assistive devices supports daily activities and facilitates the occupation.

Originality/value

+TUO is a pilot study that explore a topic already discussed in the scientific arena, without focusing on the specific use of low-cost 3DP technologies.

Abstract

Purpose

The purpose of this paper is to evaluate the existing scenarios for 3D printing (3DP) in order to identify the “white space” where future opportunities have not been proposed or developed to date. Based around aspects of order penetration points, geographical scope and type of manufacturing, these gaps are identified.

Design/methodology/approach

A structured literature review has been carried out on both academic and trade publications. As of the end of May 2016, this identified 128 relevant articles containing 201 future scenarios. Coding these against aspects of existing manufacturing and supply chain theory has led to the development of a framework to identify “white space” in the existing thinking.

Findings

The coding shows that existing future scenarios are particularly concentrated on job shop applications and pull-based supply chain processes, although there are fewer constraints on geographical scope. Five distinct areas of “white space” are proposed, reflecting various opportunities for future 3DP supply chain development.

Research limitations/implications

Being a structured literature review, there are potentially articles not identified through the search criteria used. The nature of the findings is also dependent upon the coding criteria selected. However, these are theoretically derived and reflect important aspect of strategic supply chain management.

Practical implications

Practitioners may wish to explore the development of business models within the “white space” areas.

Originality/value

Currently, existing future 3DP scenarios are scattered over a wide, multi-disciplinary literature base. By providing a consolidated view of these scenarios, it is possible to identify gaps in current thinking. These gaps are multi-disciplinary in nature and represent opportunities for both academics and practitioners to exploit.

Abstract

Purpose

3D printing (3DP), which is technically known as additive manufacturing, is being increasingly used for the development of bespoke products within a broad range of commercial contexts. The purpose of this paper is to investigate the potential for this technology to be used in support of the preparation and response to a natural disaster or complex emergency and as part of developmental activities, and to offer a number of key insights following a pilot trial based in the East African HQ of a major international non-governmental organisation.

Design/methodology/approach

Using an illustrative example from the water, sanitation and hygiene (WASH) field this paper demonstrates, from both a theoretical and practical standpoint, how 3DP has the potential to improve the efficiency and effectiveness of humanitarian logistic (HL) operations.

Findings

Based on the pilot trial, the paper confirms that the benefits of 3DP in bespoke commercial contexts – including the reduction of supply chain lead times, the use of logistic postponement techniques and the provision of customised solutions to meet unanticipated operational demands – are equally applicable in a humanitarian environment. It also identifies a number of key challenges that will need to be overcome in the operationalisation of 3DP in a development/disaster response context, and proposes a hub-and-spoke model – with the design and testing activities based in the hub supporting field-based production at the spokes – to mitigate these.

Research limitations/implications

In addition to an extensive review of both the HL and additive manufacturing literature, the results of the pilot trial of 3DP in support of humanitarian operations, are reported. The paper recommends further detailed analysis of the underpinning cost model together with further field trials of the recommended organisational construct and testing of the most appropriate materials for a given artefact and environment.

Practical implications

3DP has the potential to improve the response to disasters and development operations through the swift production of items of equipment or replacement spare parts. With low capital and running costs, it offers a way of mitigating delays in the supply chain through on site fabrication to meet an identified requirement more swiftly and effectively than via the traditional re-supply route, and it allows for adaptive design practice as multiple iterations of a product are possible in order to optimise the design based on field testing.

Social implications

The logistic challenges of responding in a disaster affected or development environment are well documented. Successful embodiment of 3DP as part of the humanitarian logistician’s portfolio of operational techniques has the potential to deliver more efficient and effective outcomes in support of the beneficiaries as well as a sense of empowerment in relation to problem solving. In addition, it has the longer term potential for the creation of a new industry (and, hence, income source) for those living in remote locations.

Originality/value

The research demonstrates that, whilst 3DP is increasingly found in a commercial environment, its use has not previously been trialled in a humanitarian context. The research reported in this paper confirms the potential for 3DP to become a game-changer, especially in locations which are logistically difficulty to support.

Abstract

Purpose

The purpose of this paper is to explore the microfactory model, the elements that enable it and its implications. The authors argue that microfactories reduce the risks and costs of innovation and that they can move various industries toward more local, adaptive and sustainable business ecosystems.

Design/methodology/approach

This conceptual paper explores several processes and practices that are relatively new; hence, it uses online secondary sources (e.g. interviews with CEOs, videos, blogs and trade magazine articles) extensively.

Findings

Given its versatility and high automation levels, the microfactory model can fill the gap between artisanal and mass production processes, boost the rate of innovation, and enable the local on-demand fabrication of customized products.

Practical implications

Currently, manufacturers generally need to make large investments when launching a new product, despite high uncertainty about customer acceptance, thus risking considerable losses. The microfactory model offers a safer alternative by allowing a firm to develop and fabricate new products and test their acceptance in a local market before mass producing them. Microfactories also enable the local on-demand fabrication of highly customized products.

Originality/value

This paper contributes to the discussion on the economic advantages and disadvantages of scale and scope, which have been insufficiently explored in the digital domain.

Abstract

Purpose

Three-dimensional printing (3DP) is an established process to print structural parts of metals, ceramic and polymers. Further, multi-material 3DP has the potentials to be a milestone in rapid manufacturing (RM), customized design and structural applications. Being compatible as functionally graded materials in a single structural form, multi-material-based 3D printed parts can be applied in structural applications to get the benefit of modified properties.

Design/methodology/approach

The fused deposition modelling (FDM) is one of the established low cost 3DP techniques which can be used for printing functional/ non-functional prototypes in civil engineering applications.

Findings

The present study is focused on multi-material printing of primary recycled acrylonitrile butadiene styrene (ABS), polylactic acid (PLA) and high impact polystyrene (HIPS) in composite form. Thermal (glass transition temperature and heat capacity) and mechanical properties (break load, break strength, break elongation, percentage elongation at break and Young’s modulus) have been analysed to observe the behaviour of multi-material composites prepared by 3DP. This study also highlights the process parameters optimization of FDM supported with photomicrographs.

Originality/value

The present study is focused on multi-material printing of primary recycled ABS, PLA and HIPS in composite form.

Abstract

Purpose

This study aims to develop a system framework to organise, manage and evaluate 3D printing (3DP) services in the cloud and help users select the best service according to application requirements.

Design/methodology/approach

Users can personalise their 3DP services based on their application requirements. The user is supplied with the performance capabilities and trust of all possible services. If the user is unable to select a service directly from the list of possible 3DP services, he/she can assign preference values for the application requirements to make a trade-off between the performance capabilities of services provided in terms of response time, manufacturing capabilities, lead time, cost and data integrity. After obtaining the finished product, the performance trust of the selected service are modified based on consumer feedback regarding their satisfaction. The accumulated input of a service's users is used to dynamically update its performance trust and is offered to new customers as a guide.

Findings

An industry case study is applied to verify the proposed methodology. The systematic order of the system framework demonstrated its efficiency in customising production based on trusted 3DP service providers.

Originality/value

The system upgraded the conventional 3DP service evaluation and selection approach. It considers the evaluation criteria of 3DP resources and the trust of service performance in the cloud context. The system favours 3DP cloud service providers. A registry tool is proposed to allow 3DP service providers to comprehensively define their services. By implementing a trust evaluation approach, 3DP service providers' trust are regularly updated based on their historical performances. In addition, a punishment mechanism is designed to motivate service providers to publish their true performance capabilities, therefore promoting a competitive environment and resulting in more reliable services.

Abstract

Purpose

The emergence and application of 3D Printing (3DP) is changing the way products are developed and reach the customer, allowing for unprecedented customisation options. Past research has focussed on the modus operandi of the technology, providing indications for wider future adoption. 3DP is predicted to complement current production processes and is anticipated to have a profound effect on the value chain and, therefore, on supply chain (SC) management. Management-related 3DP research has, however, been largely fragmented in terms of analysing the strategic deployment of 3DP and the corresponding effects on performance objectives. The aim of this paper is to identify, define and exemplify typical 3DP deployment strategies pursued.

Design/methodology/approach

The approach taken is a critical literature review, synthesising and interpreting past research on cross-industry deployment of 3DP, including illustrative examples. This enabled the development of a framework of current stage knowledge.

Findings

Building on past research, the authors propose a conceptual framework to be used as a classification system for 3DP operations, based on process and SC level configurations across different industries. They discuss the potential impact on operations performance objectives and then highlight research gaps, proposing specific research avenues to enhance understanding of the effects of 3DP adoption on SCs.

Practical implications

The proposed framework outlines strategic guidelines for 3DP and provides practitioners with the range of strategic options available for 3DP deployment and anticipated impacts on performance.

Originality/value

The framework can be used to map 3DP deployment at an operational level and identify the likely impact on performance objectives. Relevant implications and a future research agenda are explored.

Abstract

Purpose

The purpose of this paper is to theoretically hypothesize and empirically test the impact of 3D printing (3DP) implementation on stock returns. It further explores how the stock returns due to 3DP implementation vary across different industry environments.

Design/methodology/approach

This paper integrates the dynamic capabilities view with contingency theory to provide a contingent dynamic capabilities (CDC) perspective on 3DP implementation. It argues that implementing 3DP enables firms to enhance their manufacturing capabilities and gain a competitive advantage, but the extent to which the competitive advantage can be realized is contingent on the fit between 3DP-enhanced manufacturing capabilities and firms’ operating environments. Those arguments are tested based on an event study of 232 announcements of 3DP implementation made by US publicly listed firms between 2010 and 2017.

Findings

The event study results show that firms implementing 3DP gain higher stock returns compared with their non-implementation industry peers over two years after the implementation. Such stock returns due to 3DP implementation are more pronounced for firms operating in more munificent, more dynamic and less competitive industry environments. Those findings are consistent with the CDC perspective.

Originality/value

This is the first research empirically examining the impact of 3DP implementation on stock returns. It provides important implications for managers to implement 3DP to enhance firms’ manufacturing capabilities and for researchers to study 3DP implementation from the CDC perspective.

Abstract

Purpose

Additive manufacturing (AM) technology has a huge influence on the real world because of its ability to manufacture massively complicated geometrics. The purpose of this study is to use CiteSpace (CS) visual analysis to identify fused deposition modeling (FDM) research and development patterns to guide researchers to decide future research and provide a framework for corporations and organizations to prepare for the development in the rapid prototyping industry. Three-dimensional printing (3DP) is defined to budget minimize manufactured input and output for aviation and the medical product industrial sectors. 3DP has implemented its potential in the Coronavirus Disease of 2019 (COVID-19) reaction.

Design/methodology/approach

First, 396 original publications were extracted from the web of science (WOS) with the comprehensive list and did scientometrics analysis in CS software. The parameters are specified in CS including the span (from 2011 to 2019, one year slice for the co-authorship and the co-accordance analysis), visualization (show the merged networks), specific criteria for selection (top 20%), node form (author, organization, region, reference cited; cited author, journal and keywords) and pruning (pathfinder and slicing network). Finally, correlating data was studied and showed the results of the visualization study of FDM research were shown.

Findings

The framework of FDM information is beginning to take shape. About hot research topics, there are “Morphology,” “Tensile Property by making Blends,” “Use of Carbon nanotube in 3DP” and “Topology optimization.” Regarding the latest research frontiers of FDM printing, there are “Fused Filament Fabrication,” “AM,” in FDM printing. Where “Post-processing” and “environmental impact” are the research hotspots in FDM printing. These research results can provide insight into FDM printing and useful information to consider the existing studies and developments in FDM researchers’ analysis.

Research limitations/implications

Despite some important obtained results through FDM-related publications’ visualization, some deficiencies remain in this research. With >99% of articles written in English, the input data for CS was all downloaded from WOS databases, resulting in a language bias of papers in other languages and neglecting other data sources. Although, there are several challenges being faced by the FDM that limit its wide variety of applications. However, the significance of the current work concerning the technical and engineering prospects is discussed herein.

Originality/value

First, the novelty of this work lies in describing the FDM approach in a Scientometric way. In Scientometric investigation, leading writers, organizations, keywords, hot research and emerging knowledge points were explained. Second, this research has thoroughly and comprehensively examined the useful sustainability effects, i.e. economic sustainability, energy-based sustainability, environmental sustainability, of 3DP in industrial development in qualitative and quantitative aspects by 2025 from a global viewpoint. Third, this work also described the practical significance of FDM based on 3DP since COVID-19. 3DP has stepped up as a vital technology to support improved healthcare and other general response to emergency situations.

Abstract

Purpose

The potential implications of the three-dimensional printing (3DP) technology are growing enormously in the various health-care sectors, including surgical planning, manufacturing of patient-specific implants and developing anatomical models. Although a wide range of thermoplastic polymers are available as 3DP feedstock, yet obtaining biocompatible and structurally integrated biomedical devices is still challenging owing to various technical issues.

Design/methodology/approach

Polyether ether ketone (PEEK) is an organic and biocompatible compound material that is recently being used to fabricate complex design geometries and patient-specific implants through 3DP. However, the thermal and rheological features of PEEK make it difficult to process through the 3DP technologies, for instance, fused filament fabrication. The present review paper presents a state-of-the-art literature review of the 3DP of PEEK for potential biomedical applications. In particular, a special emphasis has been given on the existing technical hurdles and possible technological and processing solutions for improving the printability of PEEK.

Findings

The reviewed literature highlighted that there exist numerous scientific and technical means which can be adopted for improving the quality features of the 3D-printed PEEK-based biomedical structures. The discussed technological innovations will help the 3DP system to enhance the layer adhesion strength, structural stability, as well as enable the printing of high-performance thermoplastics.

Originality/value

The content of the present manuscript will motivate young scholars and senior scientists to work in exploring high-performance thermoplastics for 3DP applications.
