Abstract
The fused filament fabrication (FFF) which is also known as freeform filament fabrication is one of the additive manufacturing techniques used for the fabrication of functional and nonfunctional prototypes. The previous studies have suggested that FFF process parameters have significant impact over the mechanical, thermal, surface, morphological and tribilogical properties of the 3D printed parts. The present study deals with the investigation for process parameters of FFF. In this study, three different process parameters namely; infill percentage, bed temperature and outer perimeter have been varied for the FFF process. The 3D printed nylon 6 prototypes (As per ASTM 638 type IV) were tested by universal tensile tester for investigation of ultimate tensile strength. The results of the study have suggested that at 100% infill percentage, 60% and 6 outer perimeters the ultimate tensile strength can be maximized.
