The advantages of using 3D printing in manufacturing include the ability to create complex designs, reduce waste, and lower production costs. 3D printing allows for rapid prototyping, enabling companies to test and iterate designs quickly. This technology can produce customized products tailored to individual specifications, enhancing customer satisfaction. Additionally, 3D printing integrates easily with additive manufacturing, making it suitable for both small-scale production and large batch runs, thereby streamlining the manufacturing process.
