Direct Investment Casting Numerical Study for ABS P400 FDM Materials

Abstract:

The purpose of this paper is to present the study of internal structure for investment casting Fused Deposition Modeling (FDM) , and compare it between open and closed ceramic cube . This research aims to introduce a new internal structure for investment casting FDM pattern. With modeling 3D-thermal condition with mechanical finite element analysis on cube ceramic shell open and closed type (during burnout stage) have been computed. As numerical observation the deformation stress for cube square 90° and hollow models with two variants cube open and closed have been evaluated by put the temperature at model. Model was be imposed until 700 °C. Several investigations indicate the probability of better performance for influencing factor drainage ability for each model. However the main scope of the paper is to compare the performance of model during burnout stage ( the deformation on ceramic shell ) . Therefore, a more analytical and practical approach will be good for future research for other mentioned factors. A new generation of internal structure (or a new build style) for investment casting FDM patterns is presented here. The significant reduction of critical loadings on ceramic shell will ensure investment casting foundries for using FDM patterns, which are by square 90° and hollow models.
