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.
