A 3D printer is a type of device that creates three-dimensional objects by layering materials based on a digital design. It is also known as additive manufacturing because it builds objects by adding material layer by layer, as opposed to subtractive manufacturing methods that involve cutting or carving away material from a larger piece.

The process of 3D printing begins with a digital model of the object, which can be created using computer-aided design (CAD) software or obtained from a 3D scanner. The digital model is then sliced into thin cross-sectional layers, and the 3D printer interprets each layer as a two-dimensional shape.

The printer uses a variety of materials, such as plastics, metals, ceramics, or even food ingredients, depending on the capabilities of the specific printer. It takes the selected material in the form of filaments, powders, or liquid resin and deposits or solidifies it layer by layer to build the object.

The 3D printing process offers several advantages, including the ability to create complex shapes and intricate details that may be challenging to achieve with traditional manufacturing methods. It also enables rapid prototyping, customization, and on-demand manufacturing, as objects can be produced quickly and easily by simply changing the digital design.

3D printers have various applications across multiple industries, including product design, architecture, engineering, medicine, education, and art. They have the potential to revolutionize manufacturing and provide new opportunities for innovation and creativity.
