FDM (Fused deposition Modeling) is a unique technique ofAM (additive manufacturing) where computers are used to build successive layers to produce a complete 3D entity. The major constraint of FDM technique is its narrow range of industrial applications, where the usage of components produced by FDM is limited to either demonstrational part or as a conceptual model rather than to be used as a fully functional component. Many studies are being continuously carried out to enlarge the spectrum of materials used which could result in increased usage of FDM in various production scenarios. Greater cost efficiencies and material process ability have drawn greater focus toward this extrusion-based technique. Many researchers have focused on developing various composite materials such as ceramic based composites, metal matrix, fiber-reinforced and polymer composites. This paper focuses to review the major developments that have taken place in developing the various samples and parameter optimization for FDM.
