3D Printing
3D Printing, also known as additive manufacturing, is a modern way to create physical objects by building them layer by layer from digital designs. Think of it like building with very precise automated hot glue guns that follow computer instructions. Engineers use this technology to create prototypes, custom parts, and even final products. It's becoming increasingly important in manufacturing because it allows for complex designs that would be difficult to make using traditional methods, saves time in product development, and can be more cost-effective for small production runs.
