A sealing ring, in particular a radial shaft sealing ring or a rod sealing ring, can be used for sealing a sealing gap which is arranged between two machine elements. The sealing ring comprises an elastically deformable polymer material and a supporting ring which is embedded in a positively locking manner in the polymer material at least in sections. The supporting ring is configured as a 3D-printed part with a multiple-layer construction of its material at least in sections. The material of the supporting ring has a greater modulus than the polymer material. The supporting ring can be widened elastically in a radial direction with respect to the center axis of the sealing ring, and has dimensionally stable first ring segments which are connected to one another in an articulated manner in the circumferential direction of the sealing ring.
