Selective Laser Melting (SLM) is an additive manufacturing technology based on melting layers of metal powder using powerful laser without traditional limits. SLM makes it possible to manufacture complex structures such as enclosed inner cavity and complex surface. However, most of the mechanical parts are designed according to the requirements of traditional processing technology. There is often material redundancy in these parts, which will seriously affect the speed of SLM printing and increase the cost of SLM printing. In this article, according to the actual working condition, the barrel of a grenade cartridge based on traditional process design was optimized using a method of interior lattice structure to achieve the goal of lightweight, to eliminate material redundancy as much as possible. Then the strength and printability of the optimized parts were verified.
