Abstract
The aim of this project is to determine the effect of built orientation on the mechanical properties of the FDM part. The built orientation that consider in this project is flat, horizontal and vertical orientation. Test specimen are fabricated using UP 3D printer with the STL file created on SolidWorks software. Two material which are PLA and ABS are used to fabricate the test specimens. Test to be carry out to determine the mechanical properties are tensile test and compression test. The properties to be analyze are tensile strength, modulus of elasticity and maximum force that can withstand by the test specimen. Test specimen with horizontal orientation has the highest tensile strength, modulus of elasticity and maximum force compare to other orientation which are 45.5 MPa, 8.53 MPa and 5.01 kN respectively for PLA material. For ABS material, the tensile strength, modulus of elasticity and maximum force for horizontal orientation are 35 MPa, 7.03 MPa and 4.99 kN respectively. In contrast, vertical orientation has the lowest tensile strength, modulus of elasticity and maximum force which are 37.1 MPa, 7.7 MPa and 3.73 kN respectively for PLA material. While for ABS material, the tensile strength, modulus of elasticity and maximum force are 21.8MPa, 6.57 MPa and 3.71 kN respectively. Besides, comparison between material shows that PLA material has better strength in all aspect compared to ABS material. Besides, the surface of fracture also being analyzed by stereo microscope to detain out the pattern of the fracture. Vertical specimen has the smooth surface of fracture while horizontal and flat orientation has uneven surface of fracture.
