ADDITIVE BUILDING

摘要

An additive building method for building a plurality of layers to form a build stack is provided. The method includes creating a variable potential difference between a conducting element at a first voltage potential and an ion source at a second voltage potential, and creating an electric field between the conducting element and the ion source. The electric field passes through the build stack to a nearest surface of the build stack which is nearest a transfer medium. The method further includes accumulating electric charge from the ion source on the nearest surface of the build stack, and transferring deposition material from a transfer medium onto the nearest surface. The strength of the field at the nearest surface of the build stack is controlled in order to cause a homogenous transfer of the deposition material on to the nearest surface.

1. An additive building method for building a plurality of layers to form a build stack, comprising:
providing a transfer medium with electrically charged particles to be deposited in successive overlying layers to provide the build stack, depositing one of the layers of charged particles of the successive overlying layers onto a substrate to provide a first layer, reducing a repulsive effect of residual charge of the first layer for a second of the layers subsequently deposited on the first layer, and depositing the a second of the layers of charged particles from the transfer medium onto the first layer, the reduction of the repulsive effect being performed such as to prevent an accumulation of residual charge resulting from the successively deposited layers and to provide homogeneous deposition of the layers.
