A rim for a wheel of a vehicle, printed with a metal alloy by a three-dimensional printing method, the rim comprising:
- a substantially circular barrel delimited by a front flange and a rear flange, the barrel comprising:
- a central rim base,
- a front fittings part for front support of a tire, located between the rim base and the front flange, and
- a rear fittings part for rear support of a tire, located between the rim base and the rear flange,
- wherein the rim is configured to be assembled on a vehicle such that the front flange is located on an outer side of the vehicle and the rear flange is located on an inner side of the vehicle,
- wherein the barrel comprises, within its thickness and in a radial cross section, a plurality of cavities,
- wherein the front fittings part comprises a front outer surface configured to come into contact with a tire, and a front inner surface opposite to said front outer surface, the front fittings part comprising a front hook and a front bead seat for the tire, the barrel comprising a front hook cavity located at least in part in the front hook, and a front bead seat cavity located at least in part between the front bead seat and the part of the front inner surface facing it, the front hook cavity and the front bead seat cavity being separated by a reinforcing wall, and
- wherein the front outer surface of the front fittings part comprises a front safety hump located between the rim base and the front bead seat, the barrel comprising a front hump cavity located between the front hump and the front inner surface of the front fittings part facing said front hump, the front hump cavity and the front bead seat cavity being separated by a consolidating wall, such that the reinforcing wall and the consolidating wall form a substantially V-shaped separating partition around the front bead seat cavity, in a radial cross section of the barrel.
