Recent Advancements in Fused Deposition Modeling

Additive manufacturing (AM) is a continuously growing field composed of numerous part‐building approaches that involve the creation of products in a layer‐by‐layer fashion. Fused deposition modeling (FDM) is a three‐dimensional printing or AM technique that is being adopted on an industrial scale and is being utilized to make parts for commercial use mainly in the medical sector these days. It has become the need of the hour to study the printing parameters of FDM to understand the print behavior and optimize process parameters to make parts with better mechanical properties. This review paper provides an understanding of development in the optimization of process parameters for various print materials like Nylon, polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), and polyether ether ketone (PEEK) by utilizing the different designs of optimization techniques like Taguchi and response surface methodology. Regarding relevant mechanical properties, the influence of process parameters like layer thickness, raster angle, build orientations, raster width, and infill density are underlined carefully. The paper also concludes the optimized parameters to obtain the best mechanical properties such as tensile and flexural strength of Nylon, PLA, PEEK, and ABS. It also provides literature with up‐to‐date references and highlights future recommendations to optimize the mechanical properties of FDM fabricated components.
