Patent attributes
An additive manufacturing system and method for the controlled positioning of particles within the various layers of an object to be fabricated. The system and method employs holographic optical tweezers technology utilizing digitally controlled optical traps to manipulate cells or particles in conjunction with digital light-based additive manufacturing to provide control over the composition of an object to be fabricated. The method uses an optical tweezers apparatus to place desired cells or particles in desired locations prior to a patterned exposure that polymerizes surrounding resin. Thus, providing users a capability of fabricating three dimensional hierarchical systems combining features spanning from the macro to microscopic scale intricacies.
