FDM printers, or Fused Deposition Modeling printers, are a type of 3D printer that create objects by melting and extruding thermoplastic filament. The printer lays down the material layer by layer, allowing for the construction of complex shapes and designs. This process is widely used for prototyping and manufacturing in various industries. These printers are popular due to their affordability and ease of use. They can work with a variety of materials, including PLA, ABS, and PETG, making them versatile for different applications. FDM printers are commonly found in schools, homes, and professional settings for creating everything from toys to functional parts.
