Additive deposition system and method

A method of additive deposition, comprising:

• generating an aerosol of additive material by an aerosol generation apparatus;
• electrostatically charging a substrate layer to an electrostatic charge of a first polarity with a substrate charging apparatus;
• selectively altering the electrostatic charge of the substrate layer surface by depositing ions onto the substrate layer using an ion deposition apparatus external to the substrate;
• electrostatically charging the generated aerosol of the additive material to a second polarity by an aerosol charging apparatus;
• selectively depositing the electrostatically charged generated aerosol of the additive material onto the substrate layer surface due to an electrostatic force caused by an electrostatic potential between the electrostatically charged aerosol of the additive material and the selectively electrostatically charge altered substrate surface layer to form a layer of deposited additive material;
• depositing a support material onto the substrate surface layer around regions of the deposited additive material such that a combination of deposited additive material and the support material form a new substrate layer;
• and
• repeating the generating, electrostatically charging the substrate layer, selectively altering, electrostatically charging the generated aerosol, selectively depositing the additive material, and depositing the support material, for each subsequent layer of the additive material to form a solid three-dimensional object of additive material.
