Abstract

Purpose

In this paper, the authors aim to address the potential of mass personalization for ceramic tableware objects. They argue that additive manufacturing (AM) is the most adequate approach to the production of such objects.

Design/methodology/approach

The authors review the manufacturing of ceramic tableware objects, both traditional techniques and AM processes, and assess which available AM technologies are suitable for the research purpose.

Findings

The authors consider binder jetting and material extrusion as the most suitable processes for the production of ceramic objects to be integrated into a mass personalization system of ceramic tableware.

Originality/value

This paper provides an original overview of traditional and innovative techniques in ceramic manufacturing, exposing not only its differences but also its commonalities. Such overview supports the conceptual design of original equipment.

Abstract

Purpose

This paper aims to present new qualitative and quantitative data about the recently released “BigRep ONE” 3 D printer led by the design of a one-off customized stool.

Design/methodology/approach

A design for additive manufacturing (DfAM) framework was adopted, with simulation data iteratively informing the final design.

Findings

Process parameters can vary manufacturing costs of a stool by over AU$1,000 and vary print time by over 100 h. Following simulation, designers can use the knowledge to inform iteration, with a second variation of the design being approximately 50 per cent cheaper and approximately 50 per cent faster to manufacture. Metrology data reveal a tolerance = 0.342 per cent in overall dimensions, and surface roughness data are presented for a 0.5 mm layer height.

Research limitations/implications

Led by design, this study did not seek to explore the full gamut of settings available in slicing software, focusing predominantly on nozzle diameter, layer height and number of walls alongside the recommended settings from BigRep. The study reveals numerous areas for future research, including more technical studies.

Practical implications

When knowledge and techniques from desktop 3 D printing are scaled up to dimensions measuring in meters, new opportunities and challenges are presented for design engineers. Print times and material costs in particular are scaled up significantly, and this study provides numerous considerations for research centers, 3 D printing bureaus and manufacturers considering large-scale fused filament fabrication manufacturing.

Originality/value

This is the first peer-reviewed study involving the BigRep ONE, and new knowledge is presented about the practical application of the printer through a design-led project. Important relationships between material volume/cost and print time are valuable for early adopters.

Abstract

Purpose

The purpose of this paper is to review the Automate Show (robots and vision) and the Promat Show (material handling) that ran jointly in Chicago, with emphasis on the new robot innovations and applications on display.

Design/methodology/approach

In‐depth interviews with exhibitors of robots, as well as system integrators who apply robots to specific categories of applications.

Findings

Telepresence robots have come of age with multiple vendors offering units. Delta robots have found a niche in quick handling of packing and order assembly tasks.

Practical implications

Customers will have to begin thinking of robots as much more that automated workers and start to envision them as tools for making it possible for people to be in more than one place at the same time. Logistics customers need to examine the abilities of the delta style robot to do more and faster order assembly than ever before.

Originality/value

A fresh look at innovations in robotic technology for users. Robots are not limited to just “heavy” lifting any more.

Abstract

This paper focuses on the role of myth in group identity maintenance. It begins by looking at the occupational group, but broadens to show how subsociety and the larger society affected the group's identity and actions. Mississippi Delta blues performers’ use of myth serves as the historical example, and this analysis shows how the group reacted to living in a segregated and racist society. Analysis of songs demonstrates how myth can play a role in tying together this subordinated group in society and perpetuate myth. How the blues subculture still employs these myths today is also addressed.

Abstract

Purpose

The purpose of this paper is to review the Promat Show (material handling) and the Automate Show (robots and vision) run jointly in Chicago with emphasis on new automation innovations for packing and order filling applications.

Design/methodology/approach

In‐depth interviews with exhibitors of material handling automation which addresses packing and order filling.

Findings

Mobile robots have come of age with multiple vendors offering units for handling goods. Delta robots have found a niche in quick handling of packing and order assembly.

Practical implications

Customers will have to begin thinking of mobile robots as much more autonomous and self‐guiding for goods handling in the warehouse. Logistics customers need to examine the abilities of the delta style robot to do more and faster picking and packing than ever before.

Originality/value

The paper provides an expert insight into how automation innovation continues to reduce cost, improve accuracy and speed of logistics and order filling.

Abstract

Purpose

The purpose of this paper is to present novel modifications to a RepRap design that increase RepRap capabilities well beyond just fused filament fabrication. Open-source RepRap 3-D printers have made distributed manufacturing and prototyping an affordable reality.

Design/methodology/approach

The design is a significantly modified derivative of the Rostock delta-style RepRap 3-D printer. Modifications were made that permit easy and rapid repurposing of the platform for milling, paste extrusion and several other applications. All of the designs are open-source and freely available.

Findings

In addition to producing fused filament parts, the platform successfully produced milled printed circuit boards, milled plastic objects, objects made with paste extrudates, such as silicone, food stuffs and ceramics, pen plotted works and cut vinyl products. The multi-purpose tool saved 90-97 per cent of the capital costs of functionally equivalent dedicated tools.

Research limitations/implications

While the platform was used primarily for production of hobby and consumer goods, research implications are significant, as the tool is so versatile and the fact that the designs are open-source and eminently available for modification for more purpose-specific applications.

Practical implications

The platform vastly broadens capabilities of a RepRap machine at an extraordinarily low price, expanding the potential for distributed manufacturing and prototyping of items that heretofore required large financial investments.

Originality/value

The unique combination of relatively simple modifications to an existing platform has produced a machine having capabilities far exceeding that of any single commercial product. The platform provides users the ability to work with a wide variety of materials and fabrication methods at a price of less than $1,000, provided users are willing to build the machine themselves.

Abstract

Purpose

The purpose of this paper is to develop taxonomy of sourcing decision-making (SDM) archetypes and explore how different contextual factors influence these archetypes when global sourcing of complex components is considered a viable option.

Design/methodology/approach

A multiple case study approach with five in-depth cases is employed. In total, 19 interviews as well as publicly available and internal data from large buying firms headquartered in Austria and Germany were collected and analyzed.

Findings

The results reveal three different SDM archetypes which are described in detail (i.e. “consensus,” “argumentation” and “cabal”). Furthermore, it is found that these archetypes are mainly influenced by three contextual factors: sourcing maturity, product complexity and leadership style. The final model comprises six propositions which illustrate how these contextual factors determine companies’ SDM archetypes.

Research limitations/implications

The study contributes to theory development at the intersection of organizational buying behavior and the (global) SDM literature. Thereby, it answers the call for more rigorous investigation of the influence of contextual factors on SDM processes.

Practical implications

The findings enable practitioners to better understand and consequently manage SDM processes and their outcomes. By supporting decision-makers in identifying SDM archetypes, this study allows sourcing managers and teams to make better decisions by avoiding problems that occur in situations in which the preferred decision-making type would result in suboptimal decisions.

Originality/value

The study provides a first step toward taxonomy of SDM archetypes and is among the first that explores their underlying contextual factors.
