3D printing, also known as additive manufacturing, is a production technique in which objects are created layer by layer from a digital design. Instead of removing material (as in milling or cutting), 3D printing builds an object by adding material, often plastic, metal, or concrete.

With this method, it’s possible to produce complex shapes, customized products, and prototypes quickly and efficiently. From medical implants and car parts to art and architecture, 3D printing is transforming how we design, make, and build.
