This is a basic video about why 3D Printing is so AWESOME
It is extremely versatile and customizable in many different ways, ranging from filament:( https://www.allthat3d.com/3d-printer-filament/ ) to print attributes
There is a massive library of 3D designs online in case you don’t know how to design your own models https://i.materialise.com/blog/en/3d-model-databases/
It is fairly easy to design your own models, you just need the basics, not much more
3D Printing can be used to solve practical problems
3D Printing is widespread in just about every field, ranging from engineering, to NASA’s space program (space aeronautics), and even medical science (biodegradable 3D printed stitching, and 3D printed organs too are in development)
