Behaviour of Acrylonitrile Butadiene Styrene (ABS) during Dewaxing Process for Investment Casting of Proximal Humerus Implant

Abstract:

Investment casting has emerged as the foremost casting process for manufacturing of complex parts where better dimensional accuracy is required. Rapid Prototyping (RP) technologies is able to manufacture prototypes from various modelling materials. Stratasys Fused Deposition Modelling (FDM) is a typical RP process that can fabricate prototypes from acrylonitrile butadiene styrene (ABS) used in investment casting process. Elimination of steps in mould making required in the traditional pattern wax preparation makes it quicker and a cost effective process. This paper characterises the behaviour of two proximal humerus ABS pattern constructions, namely solid and hollow fabricated by the FDM 2000 during flash dewaxing process. The dewaxing process parameters such as, temperature and time were regulated and the remaining weight of ABS material in the ceramic mould was examined.
