The additive manufacturing (AM) can freely process the shape of the product compared to the conventional subtractive manufacturing(SM), and there is an advantage in reducing the weight of the product. The weight reduction of the product is mainly achieved by making a certain cavity inside the product. Therefore, in addition to the Bravais lattice structure that has been used as a three-dimensional cavity pattern, an additional new lattice structure is proposed, and the stress distribution in the lattice structure will be confirmed through simple compressive stress analysis. Based on this, we will check which structure shows the most universally excellent mechanical properties.
