Additive manufacturing, also known as 3D printing, is a production process that creates objects by layering materials such as metals, plastics, and ceramics, allowing for complex geometries and customized products. As the tech community continues to adopt additive manufacturing, it's transforming industries like aerospace, healthcare, and automotive by enabling rapid prototyping, reducing material waste, and increasing product complexity, making it a key area of interest for innovators and manufacturers looking to stay ahead of the curve.
