This research investigates Sculpting Methods and Phases of the Creative Process from a technical point of view by investigating 3D printed objects of the Japanese modern sculptor Tsuruzo ISHII’s woodwork masterpieces “Shimazaki Toson” (“Toson-zo (1)”, “Toson-zo (2)”), showing how this research discovered mechanisms of modern sculpture. In a rare case in art history, Tsuruzo left numerous saw-cut wood pieces to present the principles of modern sculpture for posterity. The construction process can be simulated using 3D capture technology and 3D digitization techniques. This research has two series of objects, “Toson 7” from “Toson-zo (1)” and “Toson 6” from “Toson-zo (2)”. “T7” and “T6” are downsized models based on the full-size 3D-scanned shape data from real wood pieces. Their “7” or “6” numbers represent the number of days in took to create them. They are created using the traditional process which is called “Kidori”. Kidori means a traditional wood carving method of “Kidori”, which is sawing away from a wooden solid, usually done for efficiency. However, Tsuruzo’s method of Kidori redefined and revolutionized it into a basic modern method of sculpture. “T7” and “T6” demonstrate basic daily steps of the creative process. By comparing them, it is deduced that the originality of sculpture is determined at the beginning of the structure, “The Base”. Analyzing these structures, this research specified the coincidence of outer structure and inner central movement, “The Armature”, which is like a rotating shaft within the solid material. These two basic structures closely relate, and their functions can be demonstrated as a phenomenon of moving or auto-morphological appositional growth of form, which is a feature of Cubism.
