Fused deposition modeling - 3D printing-a review of materials and process parameters.

This paper represents a literature review on FDM-3D printing technique in additive manufacturing, Several variables affect the end product's features in fused deposition modelling (FDM), and these variables must be considered while selecting process settings. The study illustrates the effects of various materials and process parameters on final product mechanical properties. It concludes that too many polymer materials can be used as a filament in FDM printing techniques. And although FDM is the most common printing process but characterization of its parameters and their signification need to be covered with more studying, and analysis experimentally and statistically (DOE techniques) in order to control the final product quality.
