Özet:

 In this study, functionally graded FG porous materials containing one or more infill patterns and infill rates were designed to fabricate porous materials with high compressive properties. For the FG material design, five types of infill patterns three 3D infill patterns: octet, gyroid, and cubic; and two 2D infill patterns: trihexagonal and concentric and two infill rates 50 and 70 were determined. Utilizing various combinations of different infill rates and infill patterns, a total of 21 FG porous samples and 5 control samples with uniform porous distribution were designed. The samples were produced using the Fused Deposition Modelling FDM, and the effect of functional grading on the compressive behavior of the porous material was investigated by conducting compression tests using an Instron 8801 testing machine. The highest compressive strength was obtained in the 70CONS sample, which was functionally graded based on infill rate, with a 54 increase compared to its corresponding control sample. By combining the concentric 2D infill pattern with the gyroid 3D infill pattern, the compressive strength of the designed GY-CONS-GY sample increased by 33 compared to the gyroid sample.
