چکیده مقاله
The fused deposition modeling FDM process is the most widely used additive manufacturing and 3D printing method One of the most important challenges of the FDM process is the strong dependence of mechanical and physical properties on printing parameters The purpose of this research is to investigate the effect of the basic printing parameter of nozzle temperature at three temperatures of 190, 200 and 210 degrees Celsius with a nozzle diameter of 0 6 mm on tensile strength Examining the results of the tensile strength of the samples showed that with a change of 20 degrees Celsius in the temperature of the nozzle, the tensile strength can change by 5 10% from 32 1 MPa to 38 1 MPa The highest tensile strength corresponds to the temperature of 210 degrees and the lowest tensile strength corresponds to the temperature of 190 degrees Also, the scanning electron microscope images of the fracture surface of the printed samples showed that all the printed samples have micro holes at the interface between the layers, and removing these micro holes is inevitable due to the nature of FDM 3D printing
