Additive manufacturing can create complex parts that could not be made in a subtractive method, as the part is created from a computer drawing layer by layer. These complex parts can be used in many different areas but minimal research into the effects of various environments on these parts has been performed. For example, these parts may be used in aviation, and exposed to jet fuel, but the effect of micro-organisms present in the jet fuel on the metal parts is unknown. In addition, since the metal parts are porous after sintering, these holes allow for the microbes to collect and grow undisturbed, while also releasing acidic metabolic products, such as sulfuric acid, that degrade the metal. The research presented here is the first step in understanding the effects of microbial-influenced corrosion, by studying the effects of sulfuric acid on the corrosion rate and tensile strength of stainless steel 420.
