Abstract
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.
Claims20
A device for producing a three-dimensional object from a solidifiable material comprising:
- an imaging unit comprising a predetermined number of discrete imaging elements;
- an imaging unit controller configured to control the discrete imaging elements, wherein each of the discrete imaging elements corresponds to a location on an exposed surface of the solidifiable material and projects electromagnetic radiation based on a corresponding scaled intensity value onto the corresponding location on the exposed surface of the solidifiable material, and each scaled intensity value is based on a corresponding compensation light intensity value and a degree of overlap between each of the locations on the exposed surface of the solidifiable material and a graphic depicting the three-dimensional object.
A method of producing a three-dimensional object from a solidifiable material, comprising:
- projecting electromagnetic radiation to each location in a plurality of locations on an exposed surface of the solidifiable material based on a scaled intensity value corresponding to the location, wherein each scaled intensity value is based on a corresponding compensation light intensity value and a degree of overlap between each of the locations on the exposed surface of the solidifiable material and a graphic depicting the three-dimensional object.
