    摘要： The invention relates to a method for producing a three-dimensional object (12) by solidifying layer by layer a material (16) that can be solidified by the action of radiation (14) using exposure masks (28), wherein at least one, preferably a single digital exposure mask is generated for forming each object layer to be solidified of the object (12) in a construction plane (22), by means of which exposure mask the radiation is projected selectively into the construction plane. According to the invention, the method is improved in that three-dimensional objects having an improved, smoother surface can be produced simply by exposing the construction plane (22) in an oscillating manner during an exposure time. The invention also relates to an improved exposure mask generation device and an improved device for producing a three-dimensional object.
