Question

Which of the following additive manufacturing technique(s) can use a wire as a feedstock material?

Correct answer (B) Fused deposition modeling; (D) Directed energy deposition processes Solution Stereolithography (SLA) uses liquid photopolymer resin. Fused Deposition Modeling (FDM) uses thermoplastic filament (often referred to as wire or string-like material). Selective Laser Sintering (SLS) uses powder material. Directed Energy Deposition (DED) processes can use either powder or wire feedstock, where the wire is melted by a laser, electron beam, or plasma arc. Therefore, FDM and DED are the techniques that can use a wire as a feedstock material. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
