Process Parameters Studies on Density and Hardness of AlSi7Mg Alloy Developed by DMLS Method

Abstract

Additive manufacturing is one of the emerging domains in the industry. The ability to build complex and accurate metallic prototypes is crucial in the verifying the design of many essential components. Direct metal laser sintering technique is a type of laser powder bed fusion methods that is used to print samples with good accuracy. Typically, Al alloys are used in these techniques, mainly due to their high mass to strength ratio and good corrosion resistance. These alloys are typically used in the automobile and aero-space industry. This research focus on the effects of DMLS technique on the density and hardness of the sample
