Fused Deposition Modeling(also: FDM, Fused Filament Fabrication, FFF)
A 3D printing process that builds objects layer by layer by extruding heated thermoplastic filament through a nozzle. FDM is the most common and affordable 3D printing technology, making it widely used in makerspaces and DIY assistive technology programs. While effective for…
Fused Filament Fabrication(also: FFF, Fused Deposition Modeling, FDM)
A 3D printing technique that creates objects by depositing melted thermoplastic filament layer by layer. FFF printers heat plastic material (commonly PLA or ABS) and extrude it through a nozzle that moves according to digital model coordinates. In accessibility applications, FFF…
