Which is an advantage of using 3D printing in product design?

The advantage of using 3D printing in product design is that it offers rapid prototyping and cost-effectiveness. This technology allows designers to quickly create physical models of their concepts, enabling iterative testing and modifications without the need for extensive setup or tooling. Rapid prototyping with 3D printing means that ideas can move from the design phase to tangible products much quicker compared to traditional manufacturing methods. This efficiency not only speeds up the development process but also reduces costs associated with materials and labor, as changes can be made directly in the digital design without the need for new molds or tools. This flexibility and efficiency make 3D printing an attractive option for designers.
