SLA
Stereolithography (also known as SL or SLA) builds parts layer-by-layer using a UV laser to solidify liquid photopolymer resins. It is commonly used to produce concept models, master patterns, large prototypes and investment casting patterns.
Advantages: High Accuracy, high productstrength.
Cons: Slow, High(er) material costs, Postprocessing time.
