So, how exactly does this technology work? In a nutshell, 3-D printing is a form of rapid prototyping and rapid manufacturing. To print a 3-D object, the manufacturer uses a 3-D computer-aided design (CAD) program to create a digital model that gets sliced into thin cross-sections called layers. During the printing process, the 3-D printer builds up successive layers of material until the entire object is completed.
