"voxel interface 3D printing: standard nozzle, ringed by 4 additional nozzles adding thin film of different material on top... interface between each printed line controlled/ customized eliminating need for multiple printheads/ unnecessary gaps or features... potential for thinner interfaces, new material combinations, integrated functions like complex 3D circuits, electromechanical devices, data-embedded composite structures, print-in-place with precise fittings... expanded applications range/ type for soft materials"
