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, each scaled intensity value is based on a corresponding compensation light intensity value selected from the group consisting of a measured light intensity value and a light intensity value interpolated from measured light intensity values, each measured light intensity value is determined by measuring a light intensity at a selected location of the exposed surface of the solidifiable material, and each scaled intensity value is selected from the group consisting of a gray scale value and a color value.
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 locations, wherein each scaled intensity value is based on a corresponding compensation light intensity value selected from the group consisting of a measured light intensity value and a light intensity value interpolated from measured light intensity values, each measured light intensity value is determined by measuring a light intensity value at a selected location of the exposed surface of a solidifiable material, and each scaled intensity value is selected from the group consisting of a gray scale value and a color value.
