Abstract
This paper focuses on the development of a distributed rapid prototyping system via the Internet to form a framework of Internet prototyping and manufacturing for the support of effective product development. The proposed methodology is targeted at a wide audience using a disparate range of computer systems to access remotely located rapid prototyping facilities via the Internet for prototype fabrication. The methodology is useful for both educational research for teaching evolving rapid prototyping technologies and remote scientific visualization. This approach is based on the merger of object‐oriented modular software architecture and client server communications for the remote control of rapid prototyping hardware (called fused deposition modeling) via the Internet. Other Web tools are used to allow the remote user to have higher interactivity with the server applications that have a direct link with the front‐end terminals controlling the rapid prototyping hardware.

Abstract
The emerging rapid prototyping technologies are having a dramatic impact on the engineering design process. When properly integrated, these technologies enable aggressive prototyping throughout the design process and reduce the likelihood of expensive design changes late in the product life cycle. Unfortunately, few engineering students get to experience first‐hand the power of rapid prototyping. Reports on an ongoing experimental introduction of physical rapid prototyping technologies into the engineering curriculum at Virginia Tech. The experiments include a senior technical elective approved for graduate credit dedicated to rapid prototyping, a pilot programme within Engineering Fundamentals, and the use of rapid prototyping equipment in Mechanical Engineering Senior Design.

The purpose of this paper is to propose a conceptual framework for prototyping outsourcing.
Abstract
Purpose
The purpose of this paper is to propose a conceptual framework for prototyping outsourcing.
Design/methodology/approach
This study provides an up‐to‐date literature review and an in‐depth case study.
Findings
This study identifies three factors (i.e. the degree of the prototyping to core competence, prototyping complexity, and supplier's capability of providing knowledge and speed for prototyping) and three types of risks (i.e. losing control over suppliers, dependency on suppliers, and supplier's lack of capabilities) for prototyping outsourcing decisions.
Practical implications
This paper provides guidelines for new product development managers in order to mitigate the risks associated with outsourcing and achieve effective prototyping.
Originality/value
This study provides a strategic outsourcing framework for prototyping.

Abstract
Purpose
Rapid prototyping can potentially accelerate the entire process of new product development (NPD), enabling a high level of customer involvement and hence new product success (NPS). This study aims to examine the relationship between prototyping and NPS, and the moderating effect of customer involvement, as well as the influence of speed of information dissemination on customer involvement.
Design/methodology/approach
Data were collected using the survey method through structured questionnaires. The key participants were management and team leaders from technology-based companies.
Findings
The results indicate that prototyping positively correlates with NPS, particularly when customer involvement is high. The speed of information dissemination, both from customers and on competitive products, has a positive impact on customer involvement.
Research limitations/implications
The study was limited by the undefined development stage of the prototype when offered for customer feedback. Future studies could focus on how customer involvement at each stage of prototype development affects NPS through a moderating effect.
Practical implications
The study confirms that investing in prototyping equipment for NPD increases the probability of NPS. Information capturing customers’ views and on competitive products in the market should be shared among the NPD teams. This could encourage better sharing of opinions and perceptions with customers about whether new products meet their wishes and expectations.
Originality/value
This study demonstrates that customer involvement moderates the relationship between prototyping and NPS. The degree of customer involvement depended on the speed of response of the customers themselves and on how well competitive product information was disseminated within the NPD team.

Abstract
Purpose
Despite the importance of the service design process, existing prototyping methods still have technical limitations, thus hampering the development of realistic service-experience simulations that can effectively reproduce service delivery situations and environments. In this study, a service-prototyping method based on 3D virtual reality (VR) technologies, the physical environment of a test bed, and related standard management procedures are described. In addition, a service-prototyping process for a servicescape is proposed based on a case study of an actual duty-free shop. The paper aims to discuss these issues.
Design/methodology/approach
The study adopts a qualitative approach, using case studies to undertake a design and improvement plans for brand guidance structures for the brand observation convenience of customers in a duty-free shop.
Findings
The findings of the study suggested environmental components and concept of 3D VR based test bed as an effective tool at the stage of service prototyping the core of new service development (NSD), and introduced practical methods for service prototyping in actual duty-free shop. The case study is significant due to the fact that it proved validity and practicality of the methods applied to service prototyping topic derivation and test process through target service analysis rather than optimal alternative selection.
Practical implications
This study emphasizes the importance of prototyping during NSD and the value of the service prototyping test bed for practical use. It also proposes guidelines for the establishment and management of the test bed.
Originality/value
In terms of service design research, this study also presented detailed operating procedures and methods through the new concept and in-depth case study of service prototyping using 3D VR technology.

Abstract
Purpose
This paper aims to argue about the involvement of additive technologies (ATs) in the prototyping issues of designing. More precisely, it reviews the literature contributions focused on the different perspectives of prototyping activities for design purposes, searching for both available knowledge and research needs concerning the correct exploitation of ATs.
Design/methodology/approach
A two-step literature review has been performed. In the first step, general information has been retrieved about prototyping issues related to design. In the second step, the literature searches were focused on retrieving more detailed information about ATs, concerning each of the main issues identified in the previous step. Extracted information has been analyzed and discussed for understanding the actual coverage of the arguments and for identifying possible research needs.
Findings
Four generally valid prototyping issues have been identified in the first step of the literature review. For each of them, available information and current lacks have been identified and discussed about the involvement of AT, allowing to extract six different research hints for future works.
Originality/value
This is the first literature review concerning AT-focused contributions that cover the complex and inter-disciplinary issues characterizing prototyping activities in design contexts.

Abstract
Recent developments in rapid prototyping provide evidence of the maturing of some areas of application. New applications continue to surface and new systems/processes are being introduced on a regular basis. The Fifth International Conference on Rapid Prototyping (Dayton, Ohio, 1994) provided an opportunity to bring together leaders in the commercial development and application of RP technology and to hear their perspectives on the current capabilities and future directions. A “Manufacturers round table” provided the forum for the audience to submit questions. Relates participants’ responses.

Abstract
Presents five case studies of industrial software projects specifically involving prototyping. Designates projects ranging from 240 person‐years to two person‐years involving large industrial corporations to small/medium software manufacturers. Analyses the benefits and limitations of prototyping. Concludes that prototyping is conducive to the quality of the product and the development process, particularly when used in conjunction with an evolutionary development strategy and when all parties are aware of the benefits and limitations.
