Have you ever played with a 3D puzzle or tried to build something out of Legos? Imagine being able to make your own toys, jewelry or even a car part, but instead of using Legos or a puzzle, you use a special kind of computer program to design it.
Once you have designed it on the computer, you can use a special machine called a 3D printer to make your creation come to life. To do this, you need to save your design in a special way. Just like how we save pictures in JPEG or PNG format, we need to save our designs in a special format called a 3D manufacturing format.
This format is like a recipe that the 3D printer can read and understand to create the physical object from the digital design. It tells the printer exactly how to layer the material (like plastic or metal powder) to create the final shape.
So, just like how you follow the instructions on a recipe card to make your favorite dessert, the 3D printer follows the instructions in the 3D manufacturing format to make your design. Once the printing is complete, you can hold the physical object in your hand, just like you would with a puzzle or Lego creation.
