CAD/CAM
/kad-kam/
Definition
Computer-Aided Design / Computer-Aided Manufacturing — the use of specialized 3D modeling software and CNC machines or 3D printers to design and produce jewelry models with extreme precision.
CAD/CAM has revolutionized jewelry manufacturing since the early 2000s. Designers use specialized software (RhinoGold, MatrixGold, CounterSketch, Stuller's CAD) to create precise 3D models of jewelry pieces. These digital files are then manufactured into physical wax or resin models using CAM technologies — either CNC milling (subtractive, cutting wax blanks) or 3D printing/stereolithography (additive, building layer by layer). The physical models are then used in lost-wax casting. CAD/CAM enables tolerances of 0.01mm, perfect symmetry, easy modification of designs, and rapid prototyping. It has largely replaced traditional hand-carving for commercial production while coexisting with artisanal hand fabrication for bespoke work.
Usage in the Trade
CAD/CAM is standard in modern jewelry workshops for designing engagement rings, fashion jewelry, and custom orders. Most jewelers work with CAD designers or use pre-designed CAD files from suppliers.
