Abstract
A method for producing an object formed through solid freeform fabrication includes dispensing a binder on successive layers of build material with a single first dispensing member; and coloring the successive layers with at least one second dispensing member, where the second dispensing member over-dispenses the first dispensing member. Another method for producing an object through solid freeform fabrication includes dispensing a first binder on successive layers of build material with a single first dispensing member; and dispensing a second binder on the successive layers of build material with at least one second dispensing member, where the second dispensing member over-dispenses the first dispensing member.
