CHARACTERIZATION OF ADDITIVE MANUFACTURED ABS AND NATURAL ABS SPECIMENS

Additive Manufacturing (AM) is a Rapid Prototyping technique. It is used for producing any real complex parts from the desired 3D CAD models. It can also manufacture prototypes. Additive Manufacturing can utilize raw materials with very minimum wastage. There are several additive manufacturing methods are available. This research work is focused on deposition modeling process. A typical 3D printer Mechanical Part Maker is used for printing tensile ASTM D638 specimens made of ABS and Natural ABS at zero degree orientation with varying densities of 11.1%, 22.2%, 33.3%, 44.4%, 55.5%, 66.6%, 77.7%, 88.8%, and 100%. CATIA V5-R20 software is used for modeling ASTM D638-type1 standard specimens and which can allow to save the models into STL files. After that, these STL files send to CURA15.04.6 software, then the software itself can slice the models mathematically and generate g-codes files. The g-coded file formats are sent to theFDM 3D printer via PRONTERFACE software which acts as interface between CURA15.04.5 and 3D printer and then the specimens printed by Mechanical Part Maker FDM 3D printer. Tensile test machine of model UTN-40 was used for conducting a tensile test. Here the results of yield stress, tensile strength, the percentage of reduction in area and percentage elongation for the variation of densities at constant printing speed, feed and orientation are observed. Finally, it is concluded that the characteristics of ABS are better than natural ABS, but the smoothness is good for natural ABS by visual appearance
