providing at least one predetermined deposit material;
providing at least one printing head operable to selectively deposit said at least one predetermined deposit material and/or said at least one predetermined printing material;
providing at least one build platform including a predetermined highly polished surface operable to operably disperse said at least one predetermined deposit material and/or said at least one predetermined printing material into a uniform base layer with a predetermined surface on an interface between the deposited said at least one predetermined deposit material and/or said at least one predetermined printing material and the build platform;
positioning said at least one printing head relative to said predetermined highly polished surface of said build platform;
depositing the at least one predetermined deposit material and/or said at least one predetermined printing material to said build platform in a predetermined plurality of layers and predetermined pattern forming the uniform base layer;
depositing additional predetermined plurality of layers of said at least one predetermined deposit material and/or said at least one predetermined printing material in a predetermined pattern forming a desired predetermined three-dimensional part including an outer finished show surface, without the use of post processing steps; and
