3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects from digital models. This technology builds objects layer by layer, using materials such as plastics, metals, ceramics, and more. The process begins with a computer-aided design (CAD) file that specifies the geometry of the object. The 3D printer interprets this file and deposits material in precise patterns to construct the object, gradually adding layers until the final piece is completed.
3D printing is distinct from traditional subtractive manufacturing techniques, where material is removed from a solid block to create parts. Instead, 3D printing adds material, which can lead to less waste and greater design flexibility. The applications of 3D printing are diverse and include prototyping, manufacturing custom parts, medical implants, aerospace components, and even consumer products. This technology allows for rapid production, customization, and the creation of complex geometries that would be difficult or impossible to achieve with traditional manufacturing methods. The evolution of 3D printing continues to expand its potential uses across various industries.
