Zbrush vs. Hand Carving, Sculpture Chairs

I had originally carved these chairs from 4'x2'x2' blocks of expanded poly styrene and had them sprayed with urethane resin. At the time, I was studying roto-casting techniques in the hope of learning the commercial viability of these pieces if they were to be produced in the manner of polyethylene peddle cars and play sets. It is also the manner in which much heavy plastic agricultural equipment is often manufactured. Polyethylene is a noble plastic. It is not only inert, its virtually impervious to almost every solvent or, corrosive chemical known to man. It can be cast in a broad spectrum of granularized colors and as such wonderfully speckled combinations of contrasting tones and colors can be achieved. The chairs were sponge painted in half a dozen contrasting tones a piece so as to emulate it's roto-cast off spring. The idea was to create single piece, light weight, indoor/out door, indestructible art furniture that would be as easily at home in a commercial setting as it would be in a residence. In choosing these methods and materials, I reasoned that if there was enough demand, these chairs and like designs could be brought to market for the same price as a little tike's play set.
 As with a fair number of past Zbrush endeavours, I set out to re-create past physical projects in order to make a methodological comparison. Now that the chairs exist as 3d models, they could easily be robotically carved and hard coated for limited production though, at a much higher price than the high volume polyethylene roto-casts earlier mentioned.
