PARAMETRIC STUDY OF FUSED DEPOSITION MODELING PROCESS

Fused depositions modeling is an additive manufacturing process in which digital three-dimensional (3D) design data is used to build up a component in layers by layer by depositing material. In contrast to traditional manufacturing techniques such as milling and forging which are based on subtractive and formative principles respectively, but, fused deposition modeling (FDM) are based on additive principle for part fabrication process. The major advantage of FDM processes is that an entire 3D consolidated assembly of parts can be fabricated in a single setup without any requirement of tooling / human intervention. Further, the fabrication of part methodology is independent of the complexity of the part geometries. FDM is very useful for various industrial applications in terms of elimination of expensive tooling and flexibility in part fabrication. The major limitation of FDM process is that performance of prototypes are sensitive to process parameter variation. The quality of the product is highly dependent on process parameters.In the present paper, the review has been made to study the some aspects of performance of FDM process. Some important conclusions have been made from the study. From the present study, it is noticed that FDM is very advantageous and well suited for advanced manufacturing industries.
