The invention provides a rotary dual magnetic field assisted DLP 3D printing device and a printing method, relates to the technical field of 3D printing, and aims to solve the problems that an existing 3D printing device based on a permanent magnet is simple in structure and single in magnetic field direction, and a composite material with enhanced material performance is difficult to obtain. The 3D printing device comprises a 3D printing module located in the middle and rotating magnetic field modules located on the two sides and oppositely arranged, each rotating magnetic field module comprises a fixing frame body, a servo motor, a driving component and a permanent magnet, and the servo motor, the driving component and the permanent magnet are arranged on the fixing frame body. And the driving part is used for driving the permanent magnet to rotate in the fixed frame body. The device can be used for manufacturing functional components of composite materials with enhanced mechanical and magnetic properties,
