What does FDM stand for in additive manufacturing?

• A. Fused Deposition Modeling
• B. Fused Depositing Modeling
• C. Fused Deposition Machine
• D. Final Deposition Modeling

Answer: (A)

Fused Deposition Modeling describes the way this additive process builds parts: by heating a thermoplastic filament and extruding it through a nozzle to lay down material in precise paths, layer by layer. The word “fused” highlights melting the filament, “deposition” refers to placing the melted material, and “modeling” captures the creation of the final geometry as layers stack and bond. This naming is historically tied to the company that popularized the method, and you’ll also see the open-source term fused filament fabrication used for the same process. The other phrasings don’t fit because they either change the action (deposition vs. depositing), misname the process as a machine, or use a word that doesn’t describe how the material is formed and added.
