FDM 3D printing, also known as fused deposition modeling, is a type of 3D printing that uses a filament of thermoplastic material to create a three-dimensional object. The filament is melted and extruded through a nozzle to create the desired shape. FDM 3D printers are some of the most popular 3D printers on the market due to their relatively low cost and easy-to-use nature. FDM 3D printing technology has a wide range of applications in both the consumer and industrial markets. In the consumer market, FDM 3D printers are commonly used to create prototypes, toys, and other small objects. In the industrial market, FDM 3D printers are used for rapid prototyping and low-volume production runs. FDM 3D printers can also be used to create molds and patterns for metal casting. FDM 3D printers work by melting and extruding a filament of thermoplastic material through a nozzle. The melted filament is then deposited onto a build platform in layers. The thickness of each layer can be controlled, typically ranging from 0.1 mm to 0.5 mm. Once the desired shape is printed, the object is allowed to cool and solidify.
