Abstract

Additive manufacturing is the potential and emerging technology widely being used to produce quality products with complicated profiles and customized features. Fused Deposition Modelling (FDM) process, a type of additive manufacturing technology using filament made of thermoplastic which is melted and subsequently extruded through nozzle. The main input process parameters of FDM are wall thickness, infill density, layer height, bed temperature, layer thickness, infill pattern, nozzle temperature etc. In this experimental work, specimens were printed by Ultimaker 2+ FDM printer using PLA (polylactic acid) material. The parameters selected for this experimental study are infill density (20%, 40%, and 60% for compressive strength and 100%, 80% and 60% for tensile strength respectively) and infill pattern (Grid and Tri Hexagon shape). The output parameters considered in this research work are printing time, weight of printed material, filament length consumed, volumetric accuracy after printing of PLA material. The effect of infill density and infill pattern were also studied on the compressive strength, tensile strength, and yield strength of PLA material.
