94339 - Experimental Study of the Tensile Behavior of Structures Obtained by Fdm Printing Process 

Fused Deposition Modelling (FDM) is one of the layer-based technologies that fall under the umbrella term “additive manufacturing”, where the desired part is created through the successive layer-by-layer addition process with high accuracy using computer aided design data. Additive manufacturing technology or as it’s commonly known, 3D printing is a rapidly growing sector of manufacturing that is incorporated in automotive, aerospace, biomedical and many other fields. In this research work presents an experimental investigation study of the tensile behavior of structures obtained by FDM printing process: the 3D printed tensile specimens are designed according to the ASTM d638 standards and printed from a digital template file using the FDM 3D printer Raise3D N2. The material chosen for this 3-D printing parameter optimization is recycled PLA. To improve mechanical properties of printed parts, tensile tests were performed to determine the yield strength and the Elastic modulus and then were processed through a mixed full factorial design, the statistical software Minitab19 was used to create and to analyse the design of experiments through varying the input parameters like infill patterns, infill density and infill cell orientation. To study the influence of output parameters with respect to input parameters, Analysis of Variance (ANOVA) was employed.
