3D printers (3D Printers), also known as three-dimensional printers (3D Printer), are devices that create three-dimensional objects by adding materials layer by layer. It uses digital model files as the basis, and uses special wax materials, powdered metals or plastics and other bondable materials to construct three-dimensional objects by printing layer by layer.
Working principle
The working principle of a 3D printer is similar to that of a traditional inkjet printer, but the output is a three-dimensional entity rather than a two-dimensional image. It uses layered processing and superposition molding technology to stack materials layer by layer to eventually form a complete three-dimensional object. Common 3D printing technologies include fused deposition modeling (FDM), stereolithography (SLA) and mask stereolithography (MSLA).
Application fields
3D printing technology is widely used in many fields, including medicine, industrial design, architecture, education, etc. In the medical field, 3D printing can be used to make customized prostheses and dental braces; in industrial design, it is used for rapid prototyping and small-batch production; in the field of architecture, 3D printing can print architectural models and even components; in the field of education, 3D printers cultivate creativity and hands-on ability.
Historical background
3D printing technology originated in the 1980s and was invented by Chuck Hull. After years of development, 3D printing technology has continued to improve, from early rapid prototyping technology to today's widespread application, becoming an important additive manufacturing technology.
