Abstract: In some examples, a system receives a representation of a lattice cell and information representing a target modified behavior of the lattice cell. The representation of the lattice cell including an arrangement of beams of the lattice cell. The system generates a modified lattice cell based on the representation of the lattice cell and the information, where the modified lattice cell includes the arrangement of the beams and an added behavior adjustment structure that is connected to a selected beam of the arrangement of the beams.

Abstract: According to one example, there is provided a method of distributing build material in a 3D printing system. The method comprises moving a build material support positioned below a hopper, the movement to cause build material stored in the hopper to be deposited on the build material support, and moving a recoater to spread build material from the build material support over a build platform to form a layer of build material thereon, and to return any excess build material back to the build material support.
