What is the primary material used in SLA 3D printing?

(i) Thermoplastic filament
(ii) Photopolymer resin
(iii) Metal powder
(iv) Ceramic slurry

Worked SolutionAI Assisted

Answer: (ii) Photopolymer resin

SLA uses a liquid photopolymer resin. A UV laser or projected UV light selectively cures the resin, causing photopolymerization and transforming the liquid resin into a solid layer.
