Imagine you're building a tower with blocks. A 3D printer uses tiny, melted filament, like soft plastic, and lays it down layer by layer, just like stacking blocks one on top of the other until your whole idea becomes a real object! It starts with a picture or model of what you want to print, and then the printer follows that picture step by step. That’s how something digital turns into something physical.
Examples
- A toy dinosaur is printed by stacking soft plastic layers one after another, like building blocks.
- Filament is melted and applied in precise spots, forming the shape of a keychain.
- Your favorite character from a video game becomes real when it’s printed layer by layer on a 3D printer.
