The main advantage of additive manufacturing technology, such as fused filament fabrication (FFF), is that it can create a 3D structure piece by piece based on the sliced input file that is sent to the 3D printer. A wire spool with a fixed diameter may often be utilized as input in the fused filament fabrication process. Using various process settings, this technique enables the 3D printing of objects made of a variety of flexible and non-flexible materials, such as Polylactic Acid (PLA). Materials used in additive manufacturing may be assessed under various testing circumstances, such as the Izod Impact Test. One popular impact testing technique for plastics is Izod. An Izod pendulum is struck by a specimen that has a notch on one side, is attached to the notch at the base of the embedment, and is not implanted in the main method. Applying the Izod impact test becomes crucial to ensure that materials used in helmets, padding, and other protective gear can withstand impacts without breaking down. The PLA test specimens are therefore constructed using the Creality Ender3 Neo 3D printer. Different machine process parameters were taken into consideration, with a specimen thickness of 6.4 mm.
