Abstract

Fused Deposition Modeling (FDM) is a fast growing Rapid Prototyping (RP) technology due to its ability to build functional parts having complex geometrical shapes in reasonable build time.The dimensional accuracy,surface roughness,mechanical strength and above all functionality of built parts are dependent on many process variables and their settings.Besides that,Rapid prototyping is technologies that able to generate a 3D object directly from the CAD file,which was opposite with the conventional machining processes.Generally,conventional machining was removing the raw materials layer by layer but rapid prototyping is adding the raw material layer by layer.This project discuss how to improving mechanical properties of fused deposition modeling printed part with optimized parameter.Therefore,to analysis about mechanical properties need to design the dog bone according to predetermined size using 3D computer aided design (CAD) model software and exporting it into Stereolithography (STL) file.In this project,twenty-seven sample of dog bone setting will be used in fabricating the prototype.Then,the sample of dog bone will be used for analysis the mechanical properties such as tensile strength and surface roughness.After that,need to analysis the mechanical properties of the sample in terms of tensile strength and surface roughness.To test the tensile strength of sample are need using the UTM machine,and for surface roughness test by using surface roughness apparatus.Then,this project will be improving the mechanical properties of fused deposition modeling printed part with optimized parameter by using Taguchi method.The particular strength of this project is with optimized parameter by using Taguchi method to improving the mechanical properties of fused deposition modeling.
