Additive manufacturing electrostatic powder deposition

An additive material manufacturing (AMM) system comprising:

• a mechanical arm-based electrostatic powder deposition sub-system comprising:
• a mechanical arm configured to rotate and swing three-hundred and sixty degrees (360°) about a center axis or in full three-dimensional motion, the mechanical arm including a first end coupled to a base and an opposing second end coupled to a rotatable joint, the base including a collecting surface coated with an electrostatic or photosensitive material configured to retain an electrical charge having a first polarity;
• and
• a powder dispenser disposed above the mechanical arm, the powder dispenser configured to deposit electrically charged powder having a second polarity to the collecting surface, the second polarity being opposite with respect to the first polarity,
• wherein the collecting surface is located proximate to an electrically charged build in response to rotating the mechanical arm, the electrically charged build having the second polarity such that an electrostatic attraction between the electrically charged powder and the electrically charged build forces the electrically charged powder to transfer from the collecting surface to the electrically charged build.

An additive material manufacturing (AMM) system comprising:

• a stamp-based electrostatic powder deposition sub-system comprising:
• a stamping press including an arm having an end coupled to a base, the base including a collecting surface coated with an electrostatic or photosensitive material configured to retain a first electrical charge;
• a powder dispenser configured to dispense powder;
• a powder tray configured to collect dispensed powder and apply a second electrical charge to the powder collected in the powder tray,
• wherein the stamping press is configured to press the base against the electrically charged powder collected in the powder tray such that the collecting surface retains a portion of the electrically charged powder based on an electrostatic attraction between the electrically charged powder and the collecting surface, and
• wherein the stamping press is configured to press the base against an electrically charged build such that the electrically charged powder is transferred from the collecting surface to the build based on an electrostatic attraction between the electrically charged powder and a third electrical charge applied to the build.
