Construction 3D printing is gaining new heights in Texas, as printing  begins on the first multistory printed structure in the United States. 

HANNAH, PERI 3D Construction, and CIVE, in collaboration with building industry partners, are printing a  two-story single-family home in Houston that integrates customized architectural design and a resilient structural  system that leverages a hybridized construction method. 

The 4,000-square foot project showcases the possibilities of 3D printing technology, mass customization and design solutions that integrate conventional construction systems.

With a hybridized construction  method that combines 3D printing with wood framing, the project’s scalable design and construction  process is applicable for multifamily housing and mixed-use construction. Using the COBOD BOD2 gantry printer, the project takes advantage of the printer’s modularity for its design layout.  

The project is the culmination of a two-year collaborative effort between boundary-pushing design researchers and industry partners. The project is spearheaded by architectural designers and assistant professors at the College of Architecture, Art, and Planning at Cornell University Leslie Lok and Sasa  Zivkovic, principals of HANNAH; along with PERI 3D Construction, an internationally leading provider for  3D construction printing, and CIVE, one of the leading engineering and design/build contractors in  Houston.  

“For the design of the project, we developed a hybrid construction approach that couples innovations in  concrete 3D printing with traditional wood framing techniques to create a building system that is  structurally efficient, easily replicable, and materially responsive,” said Leslie Lok and Sasa Zivkovic, of  HANNAH. “The project also highlights the exciting design potential of mass-customized architectural  components to meet homeowner’s needs and to simplify building system integration. These design efforts  aim to increase the impact, applicability, sustainability, and cost efficiency of 3D printing for future  residential and multi-family buildings in the U.S.”  

Collectively, the team has extensive experience in 3D printing. HANNAH is an innovative architectural design practice known for its progressive design solutions.

PERI 3D Construction has an extensive record of advancing the implementation of 3D printing in building construction. Using COBOD BOD2 printers, PERI has completed six projects in Europe and in the U.S.

“We are incredibly proud to not only showcase the possibilities of the BOD2 3D construction printer but also our extensive know-how in planning, engineering, and printing on this project, which is the seventh and largest one we printed so far,” said Fabian Meyre-Broetz, CEO of PERI 3D Construction. “We are  convinced that it will set new standards from a design as well as printing execution perspective and  underlines our role as the forerunner for this new construction technique.”

The project also developed detailed solutions with key building industry partners from construction  material to HVAC systems. The team calibrated printing parameters with Quikrete’snew generation of  printable concrete. 

Working with Huntsman Building Solutionsand their R&D research team, the  building integrates a closed-cell foam insulation system. 

The hybridized construction utilizes Simpson  Strong-Tie’s anchoring systems for both 3D printed elements and wood connections. The residential  building deploys Carrier’s state-of-the-art Variable Refrigerant Flow (VRF) technology for an efficient  HVAC system that is translatable to larger scale housing and multi-family construction.  

“Having the opportunity to be the engineers and general contractor for the first multistory 3D printed  structure in the U.S. has been an honor,” said Hachem Domloj, CIVE president. “We can see how this  technology and our team’s approach is providing the scalability to larger commercial developments.  Collectively, we're changing the way our country builds, and paving the way for more affordable  housing, higher structural integrity, and faster building capabilities. The possibilities of 3D printing are  endless!”
