Micro-optics fabrication using tomographic additive manufacturing

A method of blurred tomography volumetric additive manufacturing, comprising:

• generating a three-dimensional representation of an object to be manufactured within a rotating vial and a target light dose for manufacturing the object;
• three-dimensional ray tracing of light rays from a pixel array through the rotating vial thereby modelling optical effects on the light rays in three dimensions as they pass through the rotating vial;
• iteratively updating the three-dimensional representation and the target light dose based on the three-dimensional ray tracing to account for the optical effects;
• rotating the vial of photocurable resin;
• projecting blurred light rays from the pixel array conforming to the updated three-dimensional representation at the updated target light dose onto the rotating vial to manufacture the object;
• removing the manufactured object from the vial and uncured resin from exterior of the object;
• and
• curing the manufactured object to solidify any uncured photocurable resin.
