Zusammenfassung:	Provided in the present invention are an electric motor, a laminated iron core, and a manufacturing method therefor, the manufacturing method being executed in an additive manufacturing printing apparatus, and comprising the following steps: S1: introducing inert gas into the additive manufacturing printing apparatus, pouring silicon steel metal particles into a forming cylinder of the additive manufacturing printing apparatus, and performing laser scanning on the silicon steel metal particles such that the silicon steel metal particles gradually melt into at least one silicon steel metal layer; S2: continuing to pour silicon steel metal particles into the forming cylinder of the additive manufacturing printing apparatus, and stopping performing laser scanning on the silicon steel metal particles or reducing the laser power executing the laser scanning, such that the silicon steel metal particles do not entirely melt and form an insulating layer; and alternating the execution of steps S1 and S2 until a laminated iron core having a plurality of alternating silicon steel metal layers and insulating layers is formed. The manufacturing method of the present invention is simple and can form a structurally complex laminated iron core, further reducing eddy current losses.
