A method for forming a multi-material part by selective laser melting includes the following steps. Modeling is performed by regularly distributing and arraying a combination of materials that meets forming requirements such that a part model is designed. The designed part model is subjected to a dimension compensation, a shape compensation, a chamfering setting, a margin design and a design of a process support to obtain a process model. The obtained process model is sliced into a series of layers. Type, distribution and boundary information of materials in each layer are collected to generate a control file. All materials required for part forming are loaded into an additive manufacturing equipment. After a state of the additive manufacturing equipment meets forming requirements, a part is formed under the control of the generated control file. Post-processing is performed after the part is formed.
