3D printing, also known as additive manufacturing, is an innovative production technique in which an object is built layer by layer based on a digital model. Instead of removing material like traditional methods, a 3D printer adds material—usually plastic, resin, or metal—precisely where it is needed. This results in high precision, efficient material usage, and unprecedented design freedom. It enables the production of complex shapes that are difficult or even impossible to achieve with conventional methods.
This technology is now widely used across sectors such as healthcare, the automotive industry, fashion, art, and manufacturing. For hobbyists and small businesses, 3D printing also offers the opportunity to quickly create prototypes, design personalized products, or realize unique creations without high startup costs. It democratizes production and makes customization more accessible than ever before.
The process starts with creating or downloading a 3D model in a special file format, usually an .STL file. This model is then loaded into a slicer program, which translates the design into layers and instructions for the printer. The printer follows these instructions, melting or curing material (such as plastic, resin, or metal) to build the object layer by layer.
