Abstract
A method and an apparatus for fabricating a structured object wherein a photo-curing material, which is cured by being irradiated with light, within successive layers is irradiated with light providing energy, which is transformed by absorption to internal energy of the photo-curing material for curing, thereby forming the object. Within each individual layer of the successive layers coarse structures of the object and fine structures of the object are identified. A first light beam is directed, which provides a single photon energy that matches the energy gap of the photo-curing material for absorption, to first focus positions within the photo-curing material. The first focus positions being associated with the coarse structures of the object within a first individual layer of the successive layers, to cure the photo-curing material at the first focus positions thereby forming the coarse structures of the object within the first individual layer.
