An overview on the materials and mechanical behavior used in fused deposition modeling


Additive manufacturing offers significant opportunities for the production of final parts and products. Fused deposition modeling is a polymer additive manufacturing process widely used to build unreinforced and fiber-reinforced thermoplastic parts using the principle of extrusion. This work aims to review the state-of- the-art of fused deposition modeling by discussing the main advantages and limitations of the process. The building and processing parameters and their influence on mechanical behavior are addressed. A lack of understanding of these relevant parameters was identified. This literature review has shown that a deeper understanding of processing and material properties is needed to enable fused deposition modeling to become a standard manufacturing process in core industries.
