Mechanical Behavior of Nylon Load Bearing Structures Fabricated by Fused Deposition Modeling

Abstract

AbstractFused deposition modeling (FDM) is an additive manufacturing (AM) technique used to create complex models, parts for demonstration and operational components/products. In FDM, process control parameters have a significant impact on the mechanical properties of the components produced. Layer thickness, infill density and raster angle are the control parameters investigated in current research. The mechanical behavior of the FDM component are evaluated using tensile and flexural strength as touchstones in this paper. The Taguchi design was used to ensure the desired process parameters for the production of Nylon material parts. The process parameters are analyzed using orthogonal array, primary effect, signal to noise ratio (S/N) along with analysis of variance (ANOVA) methods. Flexibility and durability of Nylon helps in obtaining thin walls with strength in 3D printing objects. Its low friction coefficient with a high melting point makes it extremely abrasion resistant and allows components such as practical interlocking gears to be used in printing.KeywordsAdditive manufacturing (AM)Process parametersTaguchi methodology(S/N) ratioAnalysis of variance
