  • Bridge tooling through layered sintering of powder 
    Booysen, Gerrie Jacobus (Bloemfontein : Central University of Technology, Free State, 2007)
    Faster mould production methods will undeniably impact positively on the product development community. Rapid Tooling (RT) concepts, in context with the product development process and related product development theories, ...
  • A calculation concept to reduce manufacturing cost on laser sintering machines 
    Starz, Anton Johannes (Bloemfontein : Central University of Technology, Free State, 2008)
    A company’s ability to produce products faster and more economically may lead to a competitive edge in the international market. The reduction of development costs and shortened development time will undeniably depend on ...
  • Designing for rapid manufacture 
    Gerber, Guillaume ([Bloemfontein?] : Central University of Technology, Free State, 2008-07)
    As the tendency to use sol id freeform fabrication (SFF) technology for the manufacture of end use parts grew, so too did the need for a set of general guidelines that would aid designers with designs aimed specifically ...
  • Evaluating the Suitability of Alumide Tooling for Injection Moulding of Different Polymers 
    Combrinck, J.; Van der Walt, J.G.; Booysen, G.J.; De Beer, D.J. (South African Journal of Industrial Engineering, 2018-11)
    This paper describes the possibility of using laser-sintered Alumide® as an alternative material for producing rapid tooling (RT) inserts. To determine the durability of Alumide® inserts for the injection moulding (IM) ...
  • Radiation field shaping through low temperature thermal-spray in radiotheraphy 
    Van der Walt, Jacobus Gert (Bloemfontein : Central University of Technology, Free State, 2009)
    Superficial cancerous lesions are commonly treated through low energy X-ray or electron radiation in radiotherapy. The treatment units that produce the radiation are equipped with square, rectangular and round applicators ...
  • Tool manufacturing by metal casting in sand moulds produced by additive manufacturing processes 
    Nyembwe, Kasongo Didier (Bloemfontein : Central University of Technology, Free State, 2012)
    In this study an alternative indirect Rapid Tooling process is proposed. It essentially consists of producing sand moulds by Additive Manufacturing (AM) processes followed by casting of tools in the moulds. Various features ...
