طراحي و ساخت دستگاه چاپگر سه بعدي به منظور استفاده در توليد انبوه

The present research, entitled Design an‎d Fabrication of an Angled Conveyor-Belt-Based Three-Dimensional Printer with a 45-Degree Printing Angle, aims to overcome the limitations of conventional 3D printers an‎d to enable continuous manufacturing an‎d the development of industrial components. In this design, by altering the printing angle an‎d employing a conveyor belt mechanism, challenges such as extensive support requirements, dimensional limitations along the printing axis, an‎d frequent interruptions in the printing process have been significantly reduced. The research methodology included mechanical design, development an‎d tuning of key software parameters, fabrication an‎d installation of a functional prototype, followed by dimensional an‎d geometric calibration tests, software parameter calibration, an‎d finally performance eva‎luations. In the software section, a dedicated configuration file was developed. Experimental results demonstrated that, after calibration, the device is capable of printing parts with an accuracy better than ±0.1 mm. Furthermore, a comparison of curved surface printing between the proposed angled printer an‎d a conventional Cartesian printer showed that surface roughness, which is dependent on the printing angle, was reduced by approximately 30–40% in the angled test samples, an‎d the stair-stepping effect was noticeably decreased by up to 29%. In addition, complex parts with large negative overhang angles were successfully printed without the need for support structures, leading to reduced printing time an‎d material consumption.
