Tennessee-based Branch Technology has announced it will begin construction of a 3D-printed house in 2017. Designed by Honolulu-based WATG, the project was initiated for the Freeform Home Design Challenge, which asked participants to design for Branch’s Cellular Fabrication (C-Fab) 3D printing technology. The small house designs were required to be between 600 and 800 square feet. Branch’s C-Fab technology involves 3D printing carbon-fiber-reinforced ABS plastic with a large robotic arm. The resulting formwork can then be covered in more traditional building materials, such as concrete or foam. Instead of the typical completely 3D printed additive technique, C-Fab uses an algorithm to formulate an interior framework for the structure. WATG’s design, entitled Curve Appeal, will be built at Branch Technology’s lab in Chattanooga, Tennessee. The house is comprised of a curving shell around an open plan. The form of the building also provides a car port. The interior of the house is divided up with class walls and a solid core.
