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 by projecting a 2D image of the spinning 3D model onto a cylinder of resin spinning at the same rate.[1][5] It is notable for its ability to build an object much more quickly than other methods using resins and the ability to embed objects within the objects.
