Surrogate Based Sensitivity Analysis of Process Equipment
The computational cost associated with the use of highfidelity Computational Fluid Dynamics (CFD) models poses a serious impediment to the successful application of formal sensitivity analysis in engineering design. Even though advances in computing hardware and parallel processing have reduced costs by orders of magnitude over the last few decades, the fidelity with which engineers desire to m...
متن کاملStudy on the Effect of Fused Deposition Modeling (FDM) Process Parameters on the Printed Part Quality
3D printing known as additive manufacturing (AM) has been applied for applications in different fields such as aerospace, automotive, biomedical, and energy industries. It is the fact that 3D printing has gained a very wide acceptance over the last decade. However, several significant hurdles prevent its wider adoption. One of the most important barriers is the quality of the printed parts. Cur...
متن کاملOptimization of Fused Deposition Modelling (FDM) Process Parameters Using Bacterial Foraging Technique
Fused deposition modelling (FDM) is a fast growing rapid prototyping (RP) technology due to its ability to build functional parts having complex geometrical shapes in reasonable build time. The dimensional accuracy, surface roughness, mechanical strength and above all functionality of built parts are dependent on many process variables and their settings. In this study, five important process p...
متن کاملA parametric study of part distortions in fused deposition modelling using three-dimensional finite element analysis
A finite element analysis (FEA) model was previously developed by the current authors to simulate the fused deposition modelling (FDM) process. The model considered coupled thermal and mechanical phenomena and incorporated an element activation function to mimic the additive nature of FDM. Due to repetitive heating and cooling in the FDM process, residual stresses accumulate in a part during de...
متن کاملThree-dimensional finite element analysis simulations of the fused deposition modelling process
Fused deposition modelling (FDM) is a layer-manufacturing technology that has been widely used for rapid prototyping applications in product design and development. Owing to the intensive energy, rapid cooling, and phase changes, parts made by FDM and other layer-manufacturing processes deviate from the designed geometry, and some require laborious post-processing. Most severe form inaccuracies...
