1. A method for determining a quality of a three-dimensional (3D) object, comprising:
(a) obtaining a set of printing parameters and a predicted state of said 3D object, which predicted state is generated using at least said set of printing parameters;
(b) printing said 3D object in accordance with said printing parameters, which printing comprises (i) bringing a feedstock in contact with a support and (ii) directing flow of electrical current from said feedstock to said support, or vice versa, while said feedstock is in contact with said support;
(c) processing at least one measured parameter of said 3D object against at least one predicted parameter of said 3D object to yield a quality measure of said 3D object, wherein said at least one measured parameter is measured during or after printing of said 3D object, and wherein said at least one predicted parameter of said 3D object is from said predicted state; and
(d) electronically outputting said quality measure.
