1. Monolithic weighing system, comprising:
a plurality of levers, and
a plurality of thin section joints,
wherein the levers are joined together by the thin-section joints, wherein the levers, on the one hand, and the thin-section joints, on the other hand, are made of different materials or of different material combinations; and
wherein the levers adjoining at least a respective one of the thin-section joints on both sides thereof comprise a first material, and wherein the thin-section joint comprises a second material, which is different from the first material,
wherein the monolithic weighing system is formed from a single-piece weighing system blank comprising different materials, produced from an additive manufacturing method, in which the different materials, including the first material and the second material, are applied in layers and are joined, to form the single-piece weighing system blank, wherein the weighing system blank has prospective lever regions and prospective thin-section joint regions, and
wherein the single-piece weighing system blank is subjected to a subtractive finishing of the weighing system blank at least on the prospective thin-section joint regions, to produce the weighing system.
