Abstract: The disclosure belongs to a technical field related to metamaterials and discloses a multi-scale three-dimensional pentamode metamaterial and an additive manufacturing method thereof. The multi-scale three-dimensional pentamode metamaterial has a body centered cubic (BCC) structure and includes a plurality of rods and a plurality of node structures. Two ends of each of the rods are connected to the node structures. Each of the rods has a cylindrical shape and is provided with a biconical through hole. From one end of the rod towards the other end of the rod, a diameter of the biconical through hole gradually decreases and then gradually increases. A chamber is formed inside each of the node structures, the biconical through hole communicates with the chamber, and the chamber is filled with a lattice structure.

Abstract: A method for forming a multi-material mechanical functional member in additive manufacturing. The method includes the following steps: S1: dividing an object to be formed into a plurality of portions, analyzing and measuring mechanical properties of each portion, and constructing a unit cell library; S2: forming a lattice structure by using a unit cell structure in the unit cell library to obtain the lattice structure corresponding to each portion; S3: selecting a raw material of the lattice structure, measuring and comparing mechanical properties of each lattice structure with the mechanical properties of each portion of the object to be formed, where when the mechanical properties of each portion are satisfied, the lattice structure is the required lattice structure, otherwise, step S2 is repeated; and S4: forming a three-dimensional model by a method of additive manufacturing to accordingly obtain the required object to be formed.
