Here’s an enlargement for George Rivera at Additive Workshop. The artist’s maquette was scanned and digital artists touched up the resulting digital file, and carved in foam on by a flat-bed CAD and a seven-axis robotic arm. Sculptors assembled the foam blocks and hand carved the surface before brushing on a layer of oil clay. Every square inch of the clay surface was gone over by hand; adding texture and sharpening details. The piece was then molded, and cast in bronze.
