Abstract: A process for producing at least one three-dimensional object by solidifying a solidifyable material, comprising the steps of: providing an object carrier capable of carrying the object to be produced; providing a material capable of solidifying when subjected to energy supply; bringing a solidifyable material carrier/provider in a position to carry/provide solidifyable material at least in a building region where solidifyable material is to be solidified; supplying, to the building region, energy capable of solidifying the solidifyable material; and sensing, measuring and/or controlling a condition selected from the group consisting of pressure and/or strain. Alternatively or in combination, contact pressure, fluid pressure and/or material flowability can be sensed and/or adjusted.

Abstract: The invention describes device and method for producing a three-dimensional object by solidifying a solidifiable material under an action of electromagnetic radiation by means of energy input via an imaging unit comprising a predetermined number of discrete imaging elements (pixels). The energy input related to a specific cross-sectional area of the three-dimensional object is controlled by exposure by means of multiple successive raster masks (bitmaps; e.g. bitmap 1 and bitmap 2 and possibly additional ones). The imaging unit is suitably controllable such that at least two masks can be generated, including a first overall mask covering the cross-sectional area (bitmap 1; with pixel-specific area elements exposing in white light) and a partial mask (bitmap 2; in which only a fraction of the area elements are exposed pixel-specifically with white light) within the overall mask. A voxel matrix may be formed.

Abstract: The invention relates to a method for producing a three-dimensional object by solidification of a material solidifiable under the action of electromagnetic radiation by means of energy input via an imaging unit comprising a predetermined number of discrete imaging elements (pixels), The method comprises performing solidification with exposure using bitmap mask. The bitmap mask may be formed from a stack of bitmap data provided by an overlap analysis of a three-dimensional volume completely or partially enclosing a three-dimensional model of at least a part of the three-dimensional object to be produced. Alternatively, bitmap mask may be formed from a two-dimensional data set comprising overlap information. Solidification may be performing with exposure using bitmap mask generated “on the fly”. The invention is also directed to devices, and a computer and a data carrier useful for performing or executing the method.
