摘要： A monolithic weighing system (100) includes a plurality of levers (120), which are joined together by thin-section joints (110). The levers, on the one hand, and the thin-section joints, on the other hand, are made of different materials or material combinations; and the levers, adjoining one of the thin-section joints on both sides thereof, have a first material (21), and the thin-section joint has a second material (22) which is different from the first material. An associated method includes (i) an additive manufacturing process, in which different materials, including the first and second material (21, 22), are applied in layers and are joined to form a single-piece weighing system blank (10), wherein the weighing system blank (10) has prospective lever regions (12) and prospective thin-section joint regions (11), and (ii) subsequent subtractive finishing of the weighing system blank at least on the prospective thin-section joint regions to obtain the weighing system.
