Question

a 3d printing process that uses tiny drops of resin that are hardened by uv light is known as what?
material jetting (mj)
fused filament fabrication (fff)
selective laser sintering (sls)
stereolithography (sla)

Explanation:

Stereolithography (SLA) is a 3D - printing process where tiny drops of resin are hardened by UV light. Material jetting can use multiple materials but is not defined by UV - cured resin drops. Fused Filament Fabrication uses filament instead of resin.

Answer:

Stereolithography (SLA)
