Abstract
A method of additive manufacturing include delivering at least one layer by either depositing a uniform layer of powder on a support and then removing a portion of the layer with a roller with a surface having spatially controlled electrostatic charge, or by depositing powder onto the surface of the roller and moving the roller relative to a support such that the spatially controllable electrostatic charge on the surface of the roller causes transfer of a corresponding portion of the powder from the roller onto the support or an underlying layer.
