Glass II is the architectural scale premier of molten glass 3D printing, exhibited as part of Milan Design Week in 2017, and reinstalled at the Museum of Modern Art in New York in 2020 as part of Neri Oxman: Material Ecology. An expanded team of glassmakers, computational designers, machine builders, and architects continued the development of the glass printing process through the evaluation of glass objects and a mechanical redesign of the printing platform. Titled G3DP2, the machine brought scale and repeatability to a process of incredible visual characteristic, allowing designers to challenge traditional roles for glass in the built environment. Three 10-foot columns were designs as self supporting shell structures as well as integrated lighting systems, and installed at the Trinnale Museum in Milan as part of the Lexus Design Awards Show. Each column was printed as 15 unique components (45 in total) with continually morphing cross-sectional geometry along its length, accounting for the continuous gradient of self-loading stress. The components are bound by a steel tension rod and compression plates at the top and bottom so that each column acts as a monolithic glass form. Six point light sources inside each column are affixed to a linear motion system traveling along its length. Digital structural design gives way to simple lighting modules, transforming the space into a kaleidoscopic display of light and shadow, the projected patterns formed through physical computation between light source and glass geometry. They connect explicitly to the design of the glass, but also expand on it, offering visitors an ever-shifting texture to their surroundings and celebrating its source, the three illuminated structures. Publications include the public exhibitions at the Museuo Triennale and MoMA, and scientific journal articles describing the development of the machine and technology behind the printed glass structures, and the design of the structures and installations themselves.
