Hex mesh is a type of mesh structure consisting of hexagonal cells. The hexagonal shape ensures that each cell has six neighbors, which allows for more efficient transfer of force and better distribution of stress. Hex mesh is commonly used in engineering, particularly in the aerospace industry, to reinforce structures and provide additional strength while minimizing weight.

It is also used in 3D printing and digital modeling to create more realistic textures and patterns. Hex mesh can be made from a variety of materials, including metals, plastics, and composites, and comes in a range of sizes and configurations depending on the application.
