Concrete 3D Printed ADUs | Fall 2021 In collaboration with Annie Carver With the trend of 3D printed concrete houses, we researched whether or not the technology could be effective in Iowa’s cooler climate. We decided to use a sine wave geometry to insulate the printed walls. Through several variations, we explored ways to minimize thermal bridging and apply conventional methods to the wall, such as waterproofing. By exploring sustainable, effective, and locally sourced insulation materials, we decided to use sheep wool in the gaps to insulate the wall. Further exploration led us to question what a wall could become with additive manufacturing. Planters and furniture can be printed by reproducing the sine waves inside and outside of the wall. This allows the wall to have more functionality while also creating a sculptural aesthetic to the concrete.

Printed as modular units, the walls can be assembled with each other or with a conventional wall assembly to incorporate windows and doors. 4
