This paper introduces a wireless 3d printer liquid sprinkler mechanism for large scale production of certain types of products in industrial applications. The 3D printer can capable of producing 3 dimensional object from a designed model. Object model design by using CAD software. The slicing software generates G-code, which gives instruction to 3d printer about its movements along three axis. Send This G-code to controller via wireless mode. 3d printer can produce a 3D object on the bed of
