What is 3D printing and how does it work?
3D printing is a manufacturing process that creates a physical object from a digital design by layering materials such as plastics, metals, and ceramics. This process is also known as additive manufacturing, as the object is created by adding layers of material on top of each other. The object is built from a digital model that is sliced into thin layers and then fed into the 3D printer.
The printer then reads the design and starts building the object layer by layer. Depending on the type of printer, the object can be created using melted plastic, powdered metal, or even liquid resin. The printing process can take anywhere from a few minutes to several days, depending on the complexity of the object and the specifications of the printer. As the technology advances, more complex and intricate designs can be printed with high precision and accuracy.
