Summary:An illumination module of a 3D printer includes a light emitter, an optical lens and a concave mirror. The optical lens has an object-side surface and an image-side surface with at least one being freeform surface. The optical lens has positive refractive power, and the light emitter is disposed at an object side of the optical lens. The concave mirror is disposed at an image side of the optical lens and served as an optical deflector.
