  • Cost model for rapid manufacturing 
    Tuomi, J.; Karjalainen, J. (Journal for New Generation Sciences, Vol 4, Issue 1: Central University of Technology, Free State, Bloemfontein, 2006)
    At Helsinki University of Technology rapid prototyping, rapid tooling and rapid manufacturing technologies and applications have been researched since late 1980s. The Integrated Design and Manufacturing research group has ...
  • A critical review of literature on cooling of injection moulds 
    Ngonda, T.N. (Interim : Interdisciplinary Journal, Vol 6, Issue 2: Central University of Technology Free State Bloemfontein, 2007)
    The paper presents a critical review of the techniques that are used to cool plastic injection moulds. It examines research on cooling of injection moulds by conventional cooling, the benefits and the limitations of the ...
  • Curved-layer fused deposition modelling 
    Singamneni, S.; Diegel, O.; Huang, B.; Gibson, I.; Chowdhury, R. (Journal for New Generation Sciences, Vol 8, Issue 2: Central University of Technology, Free State, Bloemfontein, 2010)
    Current fused deposition modelling (FDM) technologies deposit material as flat layers. The result is a "stair-case" effect on non-vertical or horizontal surfaces, and compromised part strength because of weakness between ...
  • Development of an experimental diaphragm valve used for velocity profiling of such devices 
    Humphreys, P.; Erfort, E.; Fester, V.; Chhiba, M.; Kotze, R.; Philander, O.; Sam, M. (Journal for New Generation Sciences, Vol 8, Issue 2: Central University of Technology, Free State, Bloemfontein, 2010)
    The design, manufacture and use of diaphragm valves in the minerals industry is becoming increasingly important since this sector is restricted from using excessive amounts of water for their operations. This forces a ...
  • Gynaecological product development facilitated through RP and Rapid Tooling 
    Barnard, L.J.; Booysen, G.J.; De Beer, D.J. (Interim : Interdisciplinary Journal, Vol 4, Issue 1: Central University of Technology, Free State, Bloemfontein, 2005)
    Atkinson distinguishes between four types of prototypes, categorised through its end-use: •Design or aesthetic prototypes •Geometrical prototypes •Functional prototypes •Technological prototypes Shigley and Mitchell ...
  • Rapid prototyping and manufacturing in medical product development 
    Truscott, M.; Booysen, G.J.; De Beer, D.J. (Interim : Interdisciplinary Journal, Vol 8, Issue 2: Central University of Technology Free State Bloemfontein, 2009)
    RP and recently RM have been key factors in the development of the manufacturing industry in assisting in the development of new products. Fortunately, the application of these technologies has been realised in the medical ...
  • Suitability of layer manufacturing technologies for rapid tooling development in investment casting of light metals 
    Dimitrov, D.; Hugo, P.A.; Deez, B. (Journal for New Generation Sciences, Vol 8, Issue 2: Central University of Technology, Free State, Bloemfontein, 2010)
    Rapid tooling (RT) in the context of this research presents the possibility of improving the traditional investment casting process by shortening lead times while still maintaining affordable costs and required quality. ...
  • Technological developments in medical applications of rapid prototyping and manufacturing technology over the last decade 
    Bibb, R. (Journal for New Generation Sciences, Vol 8, Issue 2: Central University of Technology, Free State, Bloemfontein, 2010)
    This paper identifies the most significant technological developments made in medical applications of rapid prototyping and manufacturing (RP&M) over the past decade. This assessment is based on a retrospective analysis ...
