3D Printer A 3D printer is a machine that uses additive manufacturing technology to create three-dimensional objects by building them layer by layer from a digital design. The process begins with a 3D model, typically designed in CAD software, which is converted into a machine-readable file such as STL or G-code. The printer deposits material, such as plastic filament, resin, metal powder, or other materials, in precise layers according to the design. Common types of 3D printers include FDM, SLA, and SLS, each suited for different materials and applications. 3D printers are widely used in industries like prototyping, manufacturing, healthcare, and education, as well as for personal projects. |
