3D printing

3D printing is like a regular printer, but instead of printing a picture or words on a piece of paper, it prints physical objects instead! It starts with a 3D design on the computer, which is like a blueprint for the object that you want to make. Then, the 3D printer reads the blueprint and builds the object layer by layer using special materials like plastic or metal. By the time it's finished, you'll have a real 3D object that you can hold in your hand!
