Computed Axial Lithography (CAL)

Instant Prints! OpenCAL Layerless 3D Printing

Computed axial lithography, or CAL, looks different from other forms of 3D printing. A vial of resin rotates while a sequence of carefully computed images are projected through the volume. Where enough light accumulates, a part forms — all at once, in just minutes. There are no layers and no support structures. Introduced by our team at UC Berkeley in 2019, the CAL process was covered by Make: in Volume 88, but now we have a...
