The printed part is subsequently post-treated by removing the binder and sintering the metal.Description:  Livermore researchers have developed a multimaterial powder bed patterning which is a new additive manufacturing method using selective powder bed patterning. Granular flow of powder is induced by applying an excitation source such as a mechanical or sonic vibration force to a nozzle.

Maintains the multi-material patterning on the powder bed. Maintains the flatness of a powder bed by removing a controllable powder layer if powder bed anomalies or material shrinkage is present. Reduces the possibility of damaging the powder bed by dragging debris generated during the printing process because the debris are lifted directly upward by the applied electric field.
