The invention discloses an additive manufacturing forming method and system and terminal equipment, relates to the technical field of additive manufacturing, and aims to solve the problems of long processing time and high cost in traditional preparation of parts with heterogeneous metal structures. The additive manufacturing forming method comprises the step that according to a laser forming path of the parts with the heterogeneous metal structures, the metal parts are formed on base materials through a selective laser melting technology. Under the condition of determining that the metal parts are formed through selective laser melting, annealing heat treatment is conducted on the metal parts formed through selective laser melting. According to the laser forming path of the parts with the heterogeneous metal structures, next metal parts are formed on the base materials through a laser cladding technology. The additive manufacturing forming method is applied to an additive manufacturing forming system. The add
