CONCEPTION ET REALISATION D'UNE IMPRIMENTE 3D

Abstract

3D printing is recognized as one of the greatest technological revolutions in the world today. It represents a very important new technique for the manufacturing processes of threedimensional solid objects. Thus in this work we have designed and realized a 3D printer prototype using the technique of Fused Filament Fabrication (FFF). The conception and realization of our 3D printer is divided into three parts: mechanical, electronic and software. To achieve the mechanical construction of our model, we first designed a concept of the mechanism, the movements of these axes are guaranteed by the stepper motors, with the addition of limit switches to ensure that the printer does not exceed the border of the print area. Then We used an Arduino MEGA board for this system to send the commands initiated from the computer and transcribed in GCODE. This system is responsible for controlling all of the stepper motors and the temperature of the print head. After the achievement of the realization phase of our 3D printer, and in order to highlight our project we have designed different 3D models on a design software called Designspark, each of these 3D models has been printed successfully, with a very satisfying result
