Abstract: A method of volumetric additive manufacturing, comprising rotating a vial of photocurable resin; creating patterns of structured light images of an object to be manufactured so that the shape of the light dose distribution matches a desired shape of the object; correcting for diffusion within the vial; projecting the patterns of structured light images via a projector onto the rotating vial of photocurable resin thereby printing the object corrected for diffusion; and removing the printed object from the vial.

Abstract: A method and apparatus are set forth for volumetric additive manufacturing (VAM) wherein light rays that are used to determine tomographic projections are modelled using ray tracing, in order to account for projector non-telecentricity and etendue in all three dimensions. The path of rays from each light source (e.g. pixel) are computed as they propagate through the VAM system. Optical effects such as refraction, transmission loss, absorption, etendue, and non-telecentricity are intrinsically accounted for via ray tracing. Using these rays, the required dose to solidify the photosensitive resin is computed.

Abstract: A volumetric additive manufacturing (VAM) process for producing a solid object having a surface layer of a multifunctional material patterned thereon involves: contacting a surface of a solid base object with a liquid composition containing a photo-initiator and a multifunctional material covalently graftable to the surface of the solid base object; and, selectively irradiating the composition at the surface of the solid base object with patterned light, the irradiating being tomographic, to initiate covalent grafting of the multifunctional material to the surface of the solid base object to pattern only a portion of the surface of the solid base object with a layer of the multifunctional material grafted thereon, where the portion of the surface of the solid base object corresponds to the selectively irradiated surface of the solid base object.

Abstract: A photoresin composition for photopatterning in an oxygen-containing environment has a viscosity of about 300 cP or higher and contains: a reactive monomer with no hydrogen atoms having a bond-dissociation energy of less than about 410 kJ/mol, the hydrogen atoms; a non-amine reducing agent; and, a Norrish Type II photo-initiator. A volumetric additive manufacturing (VAM) process involves: immersing a solid base object in a liquid photoresin composition containing a photo-initiator and a multifunctional material; removing the solid base object with a film coating thereon from the liquid photoresin composition; and, selectively irradiating the composition at the surface of the object with patterned light to initiate covalent grafting or adhesion of the multifunctional material to the surface of the object to pattern only a portion of the surface of the object, where the portion of the surface of the object corresponds to the selectively irradiated surface of the object.

Abstract: A multiplexed light field projector device and a multiplexed light field display to output a light field image is described. The projector has a projector base with a projection optical system configured to output light rays to form a projected image, a collimating optical system configured for collimation of the projected image light rays to form a second projected image, which is directed to a display optical system to produce a light field image. Light field projector devices or alternative projector devices may be used individually or in combination with one or more other projectors which can be arranged to form a multiplexed direct projection light field display. The arrangement of projector devices may have an individual or shared display optical system.

Abstract: A direct projection light field display comprising an array of projectors for direct projection of a light field. The overall design and incorporation of additional optics achieve the optimal light distribution and small pixel size to produce a high definition, 3D display. The architecture of the direct projection light field display has low a brightness requirement for each projector, resulting in an increased projector density, decreased system, and a decreased power requirement, while producing a high-definition light field.

Abstract: A photoresin formulation for volumetric additive manufacturing contains a photo-curable mixture of: a monomer (e.g., an acrylate-based monomer); a photoinitiator; a polymerization inhibitor (e.g., molecular oxygen (O2)); and, a reducing agent reactive with a free radical species (e.g., a peroxyl radical) formed from the polymerization inhibitor. The reducing agent permits faster printing of objects from the photoresin formulation in a volumetric additive manufacturing process to produce 3D objects of high fidelity.
