Abstract
A composite release film may be configured to separate a current cured layer from a photocuring surface during a photocuring three-dimensional (3D) printing process. The composite release film may include a plastic layer and an elastic layer. An upper surface of the plastic layer may be the photocuring surface, and a lower surface of the plastic layer may fit with an upper surface of the elastic layer. The elastic layer may include an elastic medium of the elastic layer and a reinforcing scaffold. The elastic medium of the elastic layer may be filled in pores of the reinforcing scaffold. The reinforcing scaffold in the elastic layer may include a plurality of protrusions on a lower surface of the elastic layer. In addition, a device and a method using the composite release film to prepare a 3D object through a photocuring 3D printing technique in the field of additive manufacturing are disclosed.
