Abstract

• This research work focus on the modelling and construction of fused deposition method (FDM) based 3D printing system, specifically focusing on optimizing the structural design and hot end thermal analysis for FDM 3D printers. The study explores strategies aimed at maximizing the accuracy and resolution of the 3D printed objects. By acknowledging the specific constraints and potentials in FDM 3D printing, researcher can better tailor their designs for FDM printing, thus enhancing outcomes. This research work emphasizes the importance of considering the capabilities and restrictions of the manufacturing method when it comes to the design process. In this research study, all the electronic and mechanical parts are successfully built and fully functional, the Cartesian coordinate positioning-based 3D printing machine printed 3d models with desired accuracy level. In terms of current regulation in Ramps controller, it was observed that the current regulator achieved the required output current to control motors such as stepper motors and heating elements, which was to simply control the current flowing on phase winding, even when facing input voltage ripple. In its real implementation, however, it was observed current spikes that might lead to motor overall life cycle reduction.
