Abstract

Retraction Method is a parameter in the Repetier software which connected to the 3D Printer introduced for the optimization of a product or process quality. The ABS product produced by Fused Deposition Modeling (FDM) has its own unique result which varies with the changes of the process parameters of the machine such as the value of z-lift, speed and length. The performance of the part produced via Folgertech machines was measured for surface roughness. In order to achieve the optimum performance of the produced part, the design of experiment was employed. In this project, an orthogonal array 27 pieces of samples were determined for 3 parameters namely: z-lift, speed and length with 3 different value each. The sample was designed using SolidWorks 2013 and fabricated using Folgertech 3D printer machines. The samples were tested for surface roughness using Mitutoyo Surftest SJ 301. The results were obtained and data was analysed. The data shows that the samples 11 with parameters combination of z-lift of 1mm, speed of 20mm/s and length of 1mm give the lowest average Ra value which is 1.33 μm while the data shows that the samples 23 with parameters combination of z-lift of 2mm, speed of 40mm/s and length of 5mm give the has the highest average Ra value which is 5.93 μm, Hence, this results show that the properties of the product produced using Folgertech 3D printer vary with the different combination of process parameters and the Retraction Method provides the solution of determining the optimum combination parameter with minimum number of experiment.
