A method of fabricating an object, comprising depositing a first layer of first object material on a support substrate electrode; applying a conductive agent material onto the first layer; depositing a first layer of charged powder on an intermediate substrate; conveying the first layer of charged powder on the intermediate substrate proximate to the first layer of first object material; and applying a transferring electric field to cause transfer of the first layer of charged powder from the intermediate substrate onto the first layer on the support substrate electrode, to form a first powder layer on the first layer on the support substrate electrode. Multiple powder layers may be deposited on the first layer. The method may be further comprised of fusing the powder layer(s) to form a first fused layer on the support substrate electrode. A related object fabrication apparatus is also disclosed.

This invention provides a roller mask for use as part of a transfer roller in an electrostatographic machine consisting of a dimensionally stable base, polymeric material adhered to the base, and means for mounting the base onto a roller core.

Electrostatographic roller mask

A toner image is transferred to a heat softened thermoplastic outer layer of a receiving sheet. The toner is transferred from an image member predominantly by heating the receiving sheet to a temperature which both softens the thermoplastic layer and, when the thermoplastic layer contacts the toner, sinters the toner sufficiently to cause toner to adhere both to the thermoplastic layer and to other particles of toner. To prevent blistering, the temperature to which the thermoplastic layer must be raised can be lowered, for example, to 100 degrees C. by also heating the image member to a temperature, above ambient, but less than the temperature that would either do damage to the image member or cause the toner to stick to it.

Improved thermal assisted transfer method and apparatus

This invention provides the method of centrifugal casting consisting of the steps of: adding a polymeric material to a centrifugal apparatus; centrifuging said polymeric material until said polymeric material is cast; removing said cast polymeric material from said centrifugal apparatus; and mounting said cast polymeric material to an outside surface of a support, whereby the air interface side of said cast polymeric material is furthest from the outside surface of the support.

Methods of making centrifugally cast parts

Imaging apparatus of the kind in which successive image portions of a length of strip material are sequentially imaged and developed, features a development device adapted to provide continuous development periods of equal duration for all image portions, regardless of intermittent operation of said apparatus. One disclosed embodiment features guide means sequentially movable at the strip-feed rate between a first position, constraining all strip portions that are within the development zone in a developing relation, and a second position wherein all such strip portions are released from the developing relation.
