Additive manufacturing builds parts using which approach?

Additive manufacturing builds parts using which approach?

• A. Layer-by-layer approach.
• B. Subtractive material removal.
• C. Molding approach.
• D. Filtration approach.

Answer: (A)

Additive manufacturing builds parts by adding material layer by layer according to a digital model. The design is sliced into thin cross-sections, and each layer is deposited or cured to match that slice. Successive layers fuse together to form the final geometry, enabling complex internal features and customization without tooling. This approach differs from subtractive methods that remove material, molding that shapes material in a mold, or filtration processes that separate or purify material rather than build a solid part.
