Topic: Manufacturing Processes
Which additive manufacturing process involves curing liquid resin using a UV laser?
- A. Fused Deposition Modeling (FDM)
- B. Selective Laser Sintering (SLS)
- C. Stereolithography (SLA)
- D. Electron Beam Melting (EBM)
Answer: C. Stereolithography (SLA)
Explanation: Stereolithography (SLA) is a 3D printing technology that operates by focusing an ultraviolet (UV) laser on to a vat of photopolymer resin. The UV energy cures and solidifies the liquid resin layer by layer.
