Experimental Analysis of Mechanical properties of PETG Material 3D Printed Material by Using Fused Deposition Modelling Technique

Abstract

Rapid prototyping technologies are able to produce physical model in layer by layer manner directly from their CAD without any tool, Dies and Fixture. Compared to traditional process the rapid prototyping is capable to manufacture complex parts easily and quickly. RP helps in earlier detection and reduction of design error. In present study parameters such as percentage infill material, Layer Thickness, orientation of specimen was varied. Infill pattern was kept Honeycomb because this structure has obtained best results as compared to other structures. Layer Thickness was varied from 0.1mm, 0.2mm, 0.3mm. Orientation parameters were varied in 00, 450, 900 with respect to horizontal plane. Using Taguchi’ Design of experimental procedure for L9 orthogonal array of three parameters with 3 different levels from 27 experiments a total of 9 experiments were selected for testing. Best tensile strength as obtained for specimen with PETG material of 0.1mm layer thickness, 60% infill, orientation perpendicular.
