  Fused Deposition Modeling (FDM) 3D printing is one of the fast-growing types of Rapid Prototyping (RP) technology. 3D printing refers to fabricating a physical object from a 3D digital model by laying down successive thin layers of material. The mechanical properties and quality of the printed objects are extensively dependent on various print parameters. This study aimed to find optimized tuning parameters of print such as nozzle diameter and speed and temperature of print to improve accuracy in the prototyped part. For this purpose, the type and material of the employed profiles were first improved during the structural design of the printer, such that the structural vibrations of the device were removed considerably. Secondly, the nozzle vibrations were reduced by the redesign of the printer’s extruder. The stop/start movement of the axes was optimized through the control of the driving stepper motors of the printer’s axes. The effect of these three optimization steps enhanced the accuracy of the printer to a considerable extent. In The experimental tests, various combinations of print parameters have been examined to find the best settings. Printing of the standard model evaluated the accuracy of the printer and confirmed the validity of the results. Manuscript profile
