3D sublimation printing film is a key consumable used in the process of 3D sublimation, a heat transfer method that allows for the decoration of three-dimensional, curved, or irregularly shaped objects. Unlike traditional 2D sublimation, which uses a flat heat press and paper to transfer designs to flat surfaces, 3D sublimation leverages a vacuum heat press or sublimation oven to achieve a full-wrap, edge-to-edge print. The film itself is a specialized, heat-transfer medium that is printed with a mirrored design and then wrapped around the object to be decorated.
