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.
