Which Additive Manufacturing process utilizes a liquid photopolymer resin and a UV light source for curing and solidification?

(i) Fused Deposition Modeling (FDM)
(ii) Stereo Lithography (SLA)
(iii) Selective Laser Sintering (SLS)
(iv) Direct Energy Deposition (DED)

Worked SolutionAI Assisted

Answer: (ii) Stereo Lithography (SLA)

SLA uses a liquid photopolymer resin as the build material. A UV laser or other UV light selectively cures the resin layer by layer according to the sliced CAD model. The cured resin solidifies to form the part.

Therefore, the correct option is SLA.
