**What is the impact of 3D printing on manufacturing?**
3D printing has drastically transformed manufacturing by allowing for additive manufacturing, where materials are built layer by layer. This technology enables rapid prototyping, customization, and reduced waste compared to traditional manufacturing methods. Companies can create complex geometries that were previously difficult to achieve, thereby accelerating product development cycles and lowering costs. Moreover, 3D printing supports sustainable practices, making it a key player in modern manufacturing.
