3D printing is a process that creates three-dimensional objects from a digital file. It works by layering materials, such as plastic or metal, to build up the desired shape. This technology allows for the production of complex designs that would be difficult or impossible to make using traditional manufacturing methods. One of the exciting aspects of 3D printing is its versatility. It is used in various fields, including medicine for creating custom prosthetics, architecture for building models, and even fashion for designing unique clothing items. As the technology advances, the possibilities for 3D printing continue to expand.
