Patent attributes
A 3D printing apparatus includes a consumable spool for winding a consumable. A consumable rewinding device includes: a driving assembly including a driving portion and a rotating shaft, the driving portion being connected to the rotating shaft for providing power to drive the rotating shaft to rotate; and a roller for bearing a consumable spool, the rotating shaft is connected to the roller, and when the rotating shaft drives the roller to rotate, the consumable spool is driven to rotate by a frictional force between the roller and the consumable spool. The 3D printing apparatus and the consumable rewinding device enable the consumable to be rewound around the consumable spool, avoiding the problem of printer jamming due to messy distribution of the consumable, have a simple structure, and is easy to implement.
