  • Computed axial lithography optimization system
    Patent number: 11809161
    Abstract: A system for determining a light intensity field for use in manufacturing a 3D object from a volume of material. The system receives a 3D specification of a 3D geometry for the 3D object that specifies voxels within the volume that contain material that is to be part of the 3D object. The system employs a cost function for effectiveness of a light intensity field in manufacturing the 3D object. The cost function may be an adjoint of an Attenuated Radon Transform that models an energy dose that each voxel would receive during manufacture of the 3D object using the light intensity field. The system applies an optimization technique that employs the cost function to generate a measure of the effectiveness of possible light intensity fields and outputs an indication of a light intensity field that will be effective in manufacturing the 3D object.

  • SYSTEMS AND METHODS FOR REACTION AND TRANSPORT ENGINEERING VIA CELLULAR FLUIDICS
    Publication number: 20210077999
    Abstract: The present disclosure relates to an engineered, additively manufactured, microfluidic cellular structure formed from a plurality of cells, wherein the cells are each formed from a plurality of interconnected elements. The cells have voids and each cell is open at upper ends thereof. The cells each communicate at a point below its upper end with a common channel. The cells are each configured to accept a fluid and operate to channel the fluid into the common channel and to hold the fluid received therein for later selective withdrawal from the structure.
