A 3D printer is a machine that creates three-dimensional objects by layering materials, such as plastic or metal, based on a digital design. This process, known as additive manufacturing, allows for the production of complex shapes that would be difficult or impossible to make with traditional methods.
3D printers are used in various fields, including engineering, medicine, and art. They can produce prototypes, custom medical implants, and even intricate sculptures. As technology advances, 3D printing is becoming more accessible, enabling individuals and businesses to create unique items tailored to their specific needs.
