Strengths

This artwork reinterprets the concept of continuity in a Möbius strip through sheet metal craftsmanship. By leaving the ends unjoined in a pseudo-structure, it creates a visual illusion of seamless unity despite its physical discontinuity.

Fabricated from 1.5 mm SUS304 stainless steel, the complex 3D curves were formed solely through manual bending without any welding. By precisely managing springback, bend radii, twist angles, and sequence, a flat metal sheet was successfully transformed into a smooth, three-dimensional form.

Featuring mathematically complex surface geometry within an apparently regular contour, this piece demonstrates a new method of expression in precision sheet metal art.
