Scale Models are physical representations of objects, structures, vehicles, environments, or systems created at a proportionally reduced or enlarged scale relative to the original subject. In digital fabrication workflows, scale models are commonly produced using 3D Printing, CNC Routing, Laser Cutting, and precision assembly techniques.
Scale modeling combines engineering, craftsmanship, artistic detailing, and fabrication workflows across architecture, transportation, gaming, industrial design, and collector communities.
Scale models are widely used in hobby fabrication, architectural visualization, engineering studies, simulation systems, historical recreation, and educational environments.
