FDM

FDM is a 3D printing process where a thermoplastic filament is heated and extruded through a nozzle, depositing material layer by layer onto a build platform. In fablab and maker contexts, FDM printers are popular because they are relatively low-cost, sturdy and easy to operate. The method is well suited for rapid prototyping and functional parts, but has limitations such as visible layer lines, anisotropic mechanical properties (weaker between layers), and constraints in surface finish and very fine details.

Filament

In a fablab context, filament is the continuous, thread-like material used as feedstock for FDM/FFF 3D printers. It is typically made from thermoplastic polymers (such as PLA, ABS, PETG, TPU) and is supplied on spools in common diameters like 1.75 mm or 2.85/3 mm. The filament is melted in the printer's hotend and extruded layer by layer to build a 3D object; material choice and printing settings affect strength, flexibility and surface finish.
