This article analyzes how vacuum casting serves as the critical "bridge" for engineers moving from fragile 3D printed concepts to mass production. It details the technical advantages of silicone tooling—including achieving ±0.2mm tolerances, processing multi-material assemblies, and producing large-scale parts (up to 2 meters)—while defining the economic "sweet spot" for low-volume builds (10–50 units) that require rigorous functional validation, such as 10,000km automotive road tests.
