The 3D printing has different processes that ultimately print objects in three dimensions. It is also called additive manufacturing. It easily make these dimensional objects from a digital file. How 3D printed object is created depends on usage of various additive processes. This is because, in such additive process, the objects are created with a method that lays down different successive material layers, and it keeps going until the whole project has been created. Every layer can be interpreted as a horizontally slice thin cross-section of the eventual object.
