FDM (Fused Deposition Modeling) is an additive manufacturing technology that creates objects layer by layer using a filament material. The process begins with a solid filament of thermoplastic material that is fed into an extrusion nozzle.
The filament is heated to its melting point and then extruded onto a build platform, where it cools and solidifies to form a solid layer. The build platform is then lowered, and the process is repeated for each subsequent layer until the entire object is complete.
FDM 3D printers are known for their versatility and accessibility. They can use a wide range of thermoplastic materials, including PLA, ABS, PETG, TPU, Nylon, and more.
These materials offer various properties such as strength, flexibility, heat resistance, and chemical resistance, allowing for a diverse range of applications.
One advantage of FDM technology is its relatively low cost compared to other 3D printing methods.
FDM printers are widely available and suitable for both professional and hobbyist use. They are commonly used for prototyping, functional part production, and even small-scale manufacturing.
FDM technology also allows for the use of support structures, which are necessary for printing complex geometries with overhangs or intricate designs.
These support structures are printed alongside the main object and can be removed or dissolved after printing.
Overall, FDM 3D printing offers an affordable and accessible means of creating functional prototypes and end-use parts using a variety of thermoplastic materials.
FDM (Fused Deposition Modeling) and FFF (Fused Filament Fabrication) are considered the same technology, and the terms are often used interchangeably.
Both FDM and FFF printers utilize the same extrusion-based process and generally use the same types of materials, including PLA, ABS, PETG, TPU, Nylon, and others.
The materials compatible with FDM printers are also suitable for FFF printers and vice versa.
Some manufacturers may use the terms FDM and FFF to differentiate between commercial-grade and consumer-grade machines, but regardless of the terminology used, the available range of materials for extrusion-based printers remains largely the same.
