Abstract
A device for the lithography-based additive manufacturing of three-dimensional structures may comprise a building platform defining a building plane, a light engine designed for the dynamic patterning of light in an exposure field of said light engine, a material transport unit comprising a first drive mechanism for transporting a material layer across the exposure field, a second drive mechanism for causing relative movement of the light engine and the building platform along a displacement path extending parallel to the building plane, a linear encoder for sensing a position and/or a velocity of the light engine relative to the building platform, and/or one or more control units configured to adjust the feeding rate of a pattern data feeder based on the position or the velocity sensed by the linear encoder.
