Computed axial lithography is a method for 3D printing based on computerised tomography scans to create objects from photo-curable resin.[1][2][3][4] The process was developed by a collaboration between the University of California, Berkeley and the Lawrence Livermore National Laboratory.[5] Unlike other methods of 3D printing, computed axial lithography does not build models through depositing layers of material, as fused deposition modelling and stereolithography does, instead it creates objects using a series of 2D images projected onto a cylinder of resin.[1][5] It is notable for its ability to build object much more quickly than other methods using resins and the ability to embed objects within the objects.
