1. A device for printing a three-dimensional object, the device comprising:
at least one material application unit to deposit at least one material for each voxel of the three-dimensional object;
a vertical cavity surface emitting laser array comprising a plurality of vertical cavity surface emitting lasers, the plurality of vertical cavity surface emitting lasers including a first vertical cavity surface emitting laser to operate at a first wavelength and a second vertical cavity surface emitting laser to operate at a second, different wavelength; and
a processor to control the material application unit and independently control each laser in the laser array, the processor programmed to receive a vector corresponding to one particular voxel, the vector including values describing properties or processing of the corresponding voxel, the processor to parse the values of the vector to determine parameters for forming the corresponding voxel and control a deposition of the at least one material for the corresponding voxel via the at least one material application unit and control an application of electromagnetic energy to the corresponding voxel according to the parameters of the vector for that specific corresponding voxel using at least one of the first vertical cavity surface emitting laser or the second vertical cavity surface emitting laser to alter at least one property of the at least one material of the corresponding voxel.
