    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 ...
  • 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 ...
  • Development of a cost estimation model for sla prototyping based on volumetric information 
    Combrinck, Jacques (Bloemfontein: Central University of Technology, Free State, 2005)
    The Stereo lithography process is a well-known process in South Africa and around the world. Quotations for designers and inventors are issued daily for the growing of a prototype of his/her invention or design. Not all ...
  • 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 ...
  • Effectiveness of PrimeCast® and Poly (Methyl Methacrylate) additive manufacturing processes to produce patterns for investment casting 
    Nkhasi, Nthateng Patricia (Bloemfontein : Central University of Technology, Free State, 2018-10)
    Investment casting is known as a “near net shape” process as it can produce parts that need very little secondary machining operations. The investment casting process is one of several metal casting processes and it has ...
