1. A wheel set, comprising:
a plurality of functional levels, at least two of the functional levels being formed in a one-piece manner of a synthetic carbon allotrope based material,
wherein the carbon allotrope based material is in a carbon allotrope layer of thickness in a range of from 0.2 to 20 μm,
wherein the carbon allotrope layer has a height greater than its thickness,
wherein the wheel set has a hollow space containing a volume forming several perfectly referenced functional levels able to directly comprise a pivot axis,
wherein an external surface of the wheel set comprises a first toothing,
wherein a first level of the plurality of the functional levels comprises a first discoid plate extending in a height direction, orthogonal to a plane formed by the first discoid plate, and comprising a first hole and a first part of the volume,
wherein the first hole communicates with a second level of the plurality of functional levels,
wherein, from the first level extends a first hub, coaxially to the first hole, connecting a plurality of arms to a felloe of the first discoid plate,
wherein the first toothing projects orthogonally from an outer periphery of the felloe,
wherein the first part of the volume of the first level is at least partially filled with a second material,
wherein the second material projects from in the height direction of the external surface to form an additional functional element of the wheel sets
wherein the second level of the plurality of the functional levels comprises a second discoid plate extending in the height direction and comprising a second hole and a second part of the volume,
wherein from the second level extends a second hub, coaxially to the second hole, from a periphery of a second toothing connected to the second hub, and
wherein the first discoid plate is connected to the second discoid plate via the plurality of arms.
