Abstract
In a method for the lithography-based generative production of a three-dimensional component, in which electromagnetic radiation emitted by an irradiation device is successively focused on focal points within a material, wherein in each case a volume element of the material located at the focal point is solidified by means of multiphoton absorption, wherein a substructure is each built up from the volume elements in a writing area of the irradiation device, the build-up of the component comprises the following steps: a) a plurality of substructures are arranged next to one another, then b) substructures are arranged one above the other so that upper substructures bridge the interface(s) between lower substructures arranged next to one another.
