Metal additive manufacturing has been created as a manufacturing technology for intricately functional products with highly specific mechanical performance requirements that might be used in a variety of technology sectors. As a result, it's critical to describe additive manufacturing materials under a variety of loading circumstances to comprehend probable differences in behavior from their conventional counterparts. This study examines the mechanical behaviour of 18Ni(350) maraging steel, a material frequently utilized in additive manufacturing applications. On maraging steel produced conventionally and additively, numerous physical and mechanical tests were conducted. Finally, the tribological performance of wear rate and coefficient of friction has been improved by 48.04% and 28.36% respectively in additively fabricated maraging steel when compared to conventionally manufactured (CMed) steel. Digital Image Correlation was used to help materials related strategies. The tests results revealed the complex behaviour of maraging steels, and the material produced using additive manufacturing appeared to have greater strength potential than conventional materials.
