A 3D printer is a machine that creates three-dimensional objects from a digital file using additive manufacturing. The following are some of the functions of a 3D printer:
• Rapid prototyping: 3D printers can create physical prototypes quickly and easily, allowing designers to test and refine their ideas before going into total production.
• Manufacturing: 3D printing creates custom parts or products, especially in low-volume or speciality production runs.
• Education: 3D printers are used in classrooms and educational institutions to teach students about design, engineering, and manufacturing.
