The 3D Printed Hemi-ellipsoidal Dome is a first-of-its-kind architectural-scale structure robotically fabricated with the Digital Construction Platform (DCP).  Using the Mediated Matter group’s Print-In-Place construction technique, an open domed structure with a diameter of 14.6m and a height of 3.7m was manufactured over a print time of 13.5 hours. The geometry of the test print is a hemi-ellipsoidal dome design, where the wall thickness of the formwork cavity decreases with height. This enables optimized structural use of the cast material while providing maximum internal volume. This test print demonstrates many of the benefits of both the Digital Construction Platform and the Print-In-Place process, including the ability to rapidly print large-scale structures, produce complex digitally controlled curvatures, and fabricate on-site.

The team gratefully acknowledges material support from Dow Chemical, along with support on the DCP v.2 from Altec and Google. Special thanks to undergraduate research assistants Selam Gano and Damien Martin for their help during the on-site print
