Machined Difference

Can the same machine-made objects be unique? Stratigraphic Manufactory – a project and exhibition for the Turkish Design Biennial – explores this question. Antwerp designers Unfold sent 7 different rapid-prototyping manufacturers around the world the same 3D files to create porcelain cups. Each manufacturer printed the same cups differently, selecting the materials and machines used, with the results showing unique “tool marks” for each. On view in Istanbul through Dec. 13.
