3D printing, also known as rapid prototyping, is a process that uses digital model files as blueprints to create objects layer by layer from adhesive materials, such as powdered metals or plastics.
Most 3D printing is performed using digital material printers. Initially, this technology was widely adopted in mold manufacturing and industrial design, primarily for creating prototypes and models. In recent years, it has increasingly been used for the direct production of certain finished products. Today, some components are already manufactured using 3D printing techniques.
The range of industries utilizing 3D printing is broad. Applications can be found in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical fields, education, geographic information systems, civil engineering, firearms, and more.
The 3D printing process begins with designing a digital 3D model using computer-aided design (CAD) software. This model is then divided into thin horizontal layers. The 3D printer follows these slices as instructions, building the object layer by layer until the final form is achieved.
