3D printing and traditional CNC hybrid manufacturing model: process selection and cost cut-off point analysis

Introduction: Hybrid manufacturing is the future of manufacturing 3D printing and traditional CNC machining have their own advantages and disadvantages: 3D printing is good at complex shapes, lightweight structures, and rapid prototyping, but it is not as good as CNC machining in terms of accuracy, surface quality, and material performance; CNC machining has high precision, high surface quality, and a mature process system, but it is not capable of complex inner cavities, conformal cooling, and customized production. Hybrid manufacturing, which combines the two, is becoming a mainstream choice for high-end manufacturing. By properly allocating tasks between the two processes, hybrid manufacturing can...
