Process and device for producing a three-dimensional object

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. bitmapand bitmapand 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; with pixel-specific area elements exposing in white light) and a partial mask (bitmap; 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. A hardness depth per voxel (volume pixel) can be specifically and precisely influenced in the solidifyable material.

Method for producing a three-dimensional object by means of mask exposure

Device 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), said device comprising a computer unit, an IC and/or a software implementation respectively with the ability of adjusting and/or controlling the energy input via a specific gray value and/or color value in a voxel matrix.

Device and method for producing a three-dimensional object by means of mask exposure

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.
