Özet

This study attempts to investigate the effect of Fused Deposition Modeling (FDM) process parameters on mechanical characteristics with Taguchi optimization method. Three different FDM process parameters including filling structures (rectilinear, triangular, and full honeycomb), occupancy rates (10, 30, and 50%), and table orientation (0, 60, and -45 degrees) were specified as variable parameters for experiments. Other parameters kept fixed for each tensile and izod impact test samples were printed in line with the ISO 527-Type IV and ISO 180-Type I standards. The results found tensile strength and izod impact values to be directly proportional to the occupancy rate. The difference between the estimation model and the results of experiments did not exceed the maximum value of 1.8%. Thus, by using the equations derived from this optimization, printing parameters can be determined for the desired tensile strength and izod impact values. By improving the material properties using modified PLA+ filament material as observed in the results, it is possible to provide support for researchers, design engineers, and manufacturer to optimize raw-material usage and margin.
