In FDM, the material is typically:

(i) Liquid resin
(ii) Powdered metal
(iii) Thermoplastic filament
(iv) Ceramic slurry

Worked SolutionAI Assisted

Answer: (iii) Thermoplastic filament

FDM generally uses thermoplastic polymers supplied as a filament, such as PLA, ABS, PETG, or nylon. The filament is heated above its softening/melting temperature and extruded through a nozzle. It cools and solidifies to build the component layer by layer.
