Abstract

The purpose of this paper is to study the collapsibility of internal structure for Acrylonitrile butadiene styrene (ABS) P400 materials as a sacrificial patterns in investment casting(IC) . Two different internal patterns structure which consist hollow and square 90° were performed by Insight software . Experiment were perform by applying 3D coupled thermal mechanical finite element analysis on cube ceramic shell during burnout stage. As numerical observation the deformation stress for cube square 90° and hollow models have been evaluated by increasing the temperature during heating up to 700℃. It is found that both pattern start to buckling over the autoclave temperature throgh simulation observations and shows no cracking defect occured at ceramic mould.
