Reconstruction of a 3D image from layered 2D images

Nihuepana

I am currently looking at constructing a model of a 3D printed item based on a sequence of images of each layer of the print.

At the moment the sequence of images are transformed to black / white and run through a Moore Neighborhood algorithm and then a voxel representation of the printed item is generated, however I'd like to know what other approaches there would be. If anyone have any experience in this and could come up with some recommendations on what fields and algorithms I should look into I would be much obliged.
