3D Printing of Apartment Buildings: Where Is the Technology Headed?
In the construction industry, 3D printing has long been associated primarily with single-story demonstration buildings: a private cottage, a small school, or a pilot project for a charitable foundation. Over the past two years, the technology has made significant inroads into another segment: multi-family housing. In Europe, the first multi-story 3D-printed residential building has already been constructed, and in the U.S., ICON has launched the Titan system—the first commercially available printer capable of printing wall structures for multi-story buildings. ICON’s $200 million funding round was led by funds managed by BlackRock and the Scottish company Baillie Gifford.
From a single-story house to an apartment building
Most of the well-known 3D printing projects in construction over the past decade have been single-story buildings: private homes, small commercial properties, and isolated social projects. The technical reason is simple—previous-generation gantry printers could only print walls up to the height of a single story, and the challenges of load-bearing structures across multiple levels, utility systems, and fire safety requirements for multi-story buildings long remained an unsolved engineering problem.
The situation is changing. In May 2026, in the town of Bezannes in eastern France, construction was completed on the ViliaSprint² residential building—currently the largest 3D-printed apartment building in Europe: 12 social housing units spread over three floors, with a total living area of 800 square meters. The project was commissioned by Plurial Novilia, a development company within the Action Logement group, and the printing was carried out by PERI 3D Construction using a COBOD BOD2 gantry-style printer with Holcim TectorPrint concrete mix. The building’s load-bearing shell was printed in 34 working days instead of the planned 50, and the total project duration was reduced by three months compared to traditional construction. Three operators worked on the print instead of the usual six, construction waste was reduced from 10% to 5%, and the optimized curvilinear geometry of the walls saved about 10% of the concrete.

Titan: The First Commercial Printer for High-Rise Buildings
Following the European example, the American company ICON launched the Titan system—it began commercial operations in March 2026. Unlike the company’s previous generations of equipment, which were capable of printing only single-story structures, Titan prints wall structures for multi-story buildings. According to ICON, the system reduces the total construction time for a typical house by approximately six weeks, decreases the labor required during the wall-erection phase, and lowers the cost of the wall structures themselves by about 40%. Titan is capable of printing the walls of a house with an area of approximately 230 square meters in less than seven days. Each system costs $899,000, and the company plans to sell the equipment to developers and construction companies, scaling up the technology through its adoption by other market participants.

Why Institutional Capital Is Flowing Into Technology
ICON has already raised approximately $700 million in investments, and its valuation reached $1.4 billion following the latest funding round—earning the company “unicorn” status. The interest from major investors stems from the structural housing shortage in the U.S.: according to Zillow’s estimates, the country is short about 4.7 million homes. Against the backdrop of rising costs for materials, financing, and labor, construction automation is emerging as one of the key drivers of productivity growth in the industry. The development of this technology is also accompanied by new financing tools: in 2026, Wells Fargo became ICON’s preferred mortgage lender, offering a 50-basis-point discount on interest rates to buyers of homes printed using the company’s technology, as well as financing developers’ purchases of the Titan complexes themselves.

Where Is the Market Heading?
According to estimates by the research firm Precedence Research, the global market for 3D printing in construction will grow from approximately $25.5 billion in 2026 to about $1.8 trillion in 2035, with a compound annual growth rate of over 60%. Forecasts from various research firms regarding this market vary significantly, which is typical for a technology in the early stages of widespread adoption; however, the general consensus is that all major players expect exponential growth over the next decade.
It is important to understand the limits of the technology today. 3D printing currently covers only part of the construction process: foundations, floor slabs, roofing, building services, and finishes are all done separately using traditional methods. For buildings taller than a few stories, issues of load-bearing capacity, fire safety codes, and certification come into play. That is precisely why the French and American examples are currently limited to three or four stories—the feasibility of full-scale, multi-story residential complexes, common in large cities, has not yet been confirmed. The claimed time and cost savings are based on pilot projects and still need to be validated in large-scale applications.
What Has Already Been Published in Ukraine
In Ukraine, 3D printing in construction is currently limited to single-story structures. In July 2024, the company 3D UTU and the “Obiymy Natsii” charitable foundation presented the family of a fallen soldier from Irpin with Ukraine’s first residential house—a 130-square-meter structure fully printed on a 3D printer—in the village of Mykhailivka-Rubezhivka in the Kyiv region. Meanwhile, in Lviv, at the initiative of the Team4UA humanitarian foundation, the Danish company 3DCP Group used COBOD’s BOD2 technology to print a 370-square-meter school designed to accommodate 100 students. Both projects are single-story structures, so the transition to multi-story printing—currently being demonstrated by Titan and the French company ViliaSprint²—is the next step, which has not yet been implemented in Ukraine.

Conclusion.
The launch of Titan and the completion of ViliaSprint² mark the transition of 3D printing in construction from the category of one-off demonstration projects to that of a technology specifically designed for multi-unit housing. For the industry, this is not yet a ready replacement for traditional construction: foundations, utility networks, finishing, and certification of high-rise structures still rely on traditional methods, and the technology’s economic viability has so far been confirmed only on a pilot scale. At the same time, institutional investments such as BlackRock’s funding round and bank financing such as the partnership with Wells Fargo signal that major capital is already being committed to scaling up the multi-family housing segment.
