3D printer is also called a three-dimensional printer. It is a process of rapid prototyping.

It uses layer-by-layer stacking to make a three-dimensional model.

The liquid photosensitive resin material, molten plastic wire, gypsum powder and other materials are sprayed with adhesive or Extrusion and other methods realize layer-by-layer stacking to form a three-dimensional entity.
