Electrophotographic multi-material 3D printer

摘要

The electrophotographic three-dimensional printer system includes at least one electrophotographic (EP) printing module employing multi-material EP printing technology. The printer system may also include one or more additional printer modules employing different patterning and deposition techniques, such as powder bed and jetted binder techniques. The EP printing module may be used to create 3D objects derived from composite toner materials that may include engineering materials treated with triboelectric materials. The composite toner material may be designed to undergo post-printing treatment, the triboelectric material may be separated from the engineering material, and the engineering material may undergo transformation.
