Multimedia courseware for teaching of rapid prototyping systems

Purpose – The purpose of this paper is to detail the development of a multimedia courseware that enhances the learning of rapid prototyping (RP) among professionals, senior year and graduate students.Design/methodology/approach – The design and development of the multimedia courseware is based on a “visit a science museum” concept where each topic can be accessed depending on the interests or the needs of users. Factors that influence learning curve such as structure of information, application of visual and auditory components and human‐computer interface are addressed and discussed.Findings – Instructions using multimedia significantly enhances the education process of RP technology. Methods to produce a good multimedia courseware have been introduced.Originality/value – This paper describes the latest version of the multimedia courseware which is an accompaniment to the third edition of the book entitled Rapid Prototyping: Principles & Applications published in 2009.

Application of rapid prototyping and tooling in customised airway management

Purpose – Tracheobronchial stents are commonly used in airway management as a form of palliation for obstruction. This form of therapy immediately relieves the patients from life‐threatening conditions and significantly improves their quality of life. In the cases of complex tracheobronchial obstruction, customised airway stents are required for effective palliation. In this work, an Airway Stent Customisation Protocol (ASCP) is introduced.Design/methodology/approach – It describes two variant routes that use a combination of rapid prototyping (RP) and rapid tooling (RT) techniques to fabricate customised airway stents in short lead times. The ASCP allows the stents to be tailored in terms of geometry, and distending strength. A brief comparison between the ASCP and other RP/RT manufacturing routes is also carried out.Findings – The ability to customise airway stents in short lead times is important as it allows surgeons to swiftly treat life‐threatening conditions arising from tracheobronchial obstructio...

Enhanced Learning of Rapid Prototyping Systems through Multimedia

Dedicated teachers around the world have continually sought to find better instructional strategies for their subjects. This paper presents the development of a multimedia application for teaching rapid prototyping to professionals and tertiary-level students. A CD-ROM was used as the instructional medium. This paper considers learning factors such as the organization and structure of the information, application of animations, visual aids and sound, the human—computer interface, and presentation styles, in relation to the CD-ROMs purpose of enhancing the education process for rapid prototyping technology.
