What if you could turn your drawing into a real object? A 3D printer can do just that! First, a digital model tells the printer what to make. The printer then builds the object layer by layer, like stacking very thin slices. Most small 3D printers use melted plastic, but some use resin or metal. After printing, you may need to clean, smooth, or remove extra supports by hand. With a 3D printer, your ideas can come to life!
