An apparatus and method for managing three-dimensional (3D) printing. The method includes receiving a video of a product being output from a 3D printer, acquiring first output information by comparing a first frame of the video and a second frame subsequent to the first frame, acquiring second output information by extracting output layer-specific trace information from a G-code of the product being output acquired from the 3D printer, and acquiring quality information of the product being output on the basis of the first output information and the second output information.
