3D printing technology is beginning to influence how homes are built—offering an alternative to traditional construction methods.

Instead of months of labor-intensive work, walls can now be created layer by layer with the help of large-scale printers. This approach is no longer hypothetical; 3D-printed homes are already in use in various parts of the world.

This newsletter explores how 3D printing is being applied to housing, what’s driving the interest, and what might lie ahead for the construction industry.

Key drivers behind the trend

The global housing sector is facing several pressures, including rising material costs, shortages of skilled labor, environmental concerns, and the need for more affordable housing. In this context, 3D printing is emerging as a potential solution. It offers the possibility of faster construction, reduced material waste, and new design capabilities.

Recent examples include 3D-printed homes in Texas, eco-friendly housing projects in Kenya, and even early-stage prototypes for extraterrestrial environments. What was once seen as experimental is now gaining traction in both the public and private sectors.

Market outlook: Early growth phase

Estimates of the current size of the residential 3D printing market vary widely—from $50 million to $1.5 billion—underscoring how nascent and evolving this segment still is. However, some forecasts predict strong growth, with annual increases of up to 100%. If these projections materialize, the sector could reach multi-billion-dollar levels by the end of the decade.

Notable players in the space

Several companies are actively developing 3D printing solutions for residential construction:

• ICON (USA): Known for projects supporting the homeless, advanced housing concepts, and partnerships with NASA. Uses proprietary materials and printing systems.

• Apis Cor (USA): Specializes in mobile printers capable of on-site builds with minimal manual input.

• COBOD (Denmark): Supplies printers for some of Europe’s tallest 3D-printed structures.

• Mighty Buildings (USA): Focuses on prefabricated components using polymer-based materials.

• WASP (Italy): Develops sustainable housing using natural materials like clay and straw.

• SQ4D (USA): Gained attention by listing and selling a 3D-printed home on Zillow.

Other international firms such as CyBe, XtreeE, Constructions-3D, and Gaudi Tech (China) are also contributing to the field.

How the technology works

The process typically involves a robotic printer—either a gantry system or a robotic arm—layering a concrete-like material based on digital blueprints. This method enables the direct construction of walls and architectural features. In some cases, printing takes place on-site; in others, components are created in a factory and assembled later.

Potential benefits include:

• Faster construction: Wall structures can be completed within 1 to 3 days.

• Reduced waste: Some companies report up to 60% less construction waste.

• Design flexibility: Complex forms and curves are easier to achieve than with traditional methods.

Scaling from pilots to communities

Initial one-off builds have evolved into larger-scale housing projects. Examples include:

• Mvule Gardens, Kenya: A 52-home development using Holcim’s 3D printing technology.

• Community First! Village, Texas: Affordable housing for individuals transitioning out of homelessness, supported by ICON.

• Mexico and Malawi: Nonprofits are using 3D printing to deliver cost-effective housing.

• Dubai: The city has set a target for 25% of all new buildings to be 3D-printed by 2030.

Regional developments

• North America: The U.S. leads with investment and pilot programs, particularly in Texas and Florida. Canada is showing increased interest.

• Europe: Countries like France, Germany, and the Netherlands are investing in research and sustainability-oriented projects.

• Middle East: The UAE is pursuing aggressive innovation goals, with Dubai at the forefront.

• Asia-Pacific: Australia and Japan are advancing prefab technologies; China continues to experiment with new approaches.

• Africa and Latin America: Focused on low-cost housing supported by NGOs and environmentally conscious cement producers.

Regulatory landscape

While regulation remains a challenge, progress is being made:

• Standards: ISO 52939 is helping to establish guidelines for printed construction.

• Codes: In the U.S., organizations such as the ICC and ASTM are working to incorporate 3D printing into building codes.

• Approvals: Municipalities are increasingly accepting 3D-printed homes through equivalency frameworks.

Overall, regulatory clarity is improving, though adoption varies by region.

Environmental considerations

Sustainability is a major focus of 3D-printed construction. The technology can reduce the environmental footprint through:

• Lower material and energy consumption.

• Use of recycled or carbon-sequestering materials.

• Smaller teams on-site, reducing transportation and associated emissions.

Several projects have already met green building certification standards, aligning with global net-zero goals.

Outlook: What’s next?

The residential 3D printing industry is still developing, but future advancements are likely to include:

• Multi-story structures

• Scaled mass customization of homes

• More prefabricated panel-based construction

• Rapid-response shelters for disaster relief

• Increased private and institutional investment

As the technology matures, 3D-printed homes may shift from novelty to a mainstream building method—especially in markets seeking speed, efficiency, and sustainability.

Study: AI's soaring energy demands reshape power grids as Big Tech races to secure electricity sources

MIT Technology Review has conducted an in-depth analysis of AI's energy consumption, revealing the staggering power demands of the industry. The report highlights how AI queries—whether text, image, or video—contribute to a growing carbon footprint, with inference (the process of AI responding to user queries) now consuming more energy than model training.

Big Tech companies are making massive investments to secure energy sources for AI expansion. Meta and Microsoft are exploring nuclear power, while OpenAI and the Trump administration have announced the Stargate initiative, a $500 billion project to build 10 AI data centers, each requiring more electricity than the state of New Hampshire. Apple and Google are also committing billions to AI infrastructure.

The study underscores how AI's energy consumption has surged since 2017, doubling data center electricity use by 2023. Unlike previous tech advancements that improved efficiency, AI is driving an unprecedented demand for power, reshaping global energy grids.

Fortnite returns to the U.S. App Store with alternative payment options

Fortnite is back on the U.S. App Store after nearly five years, following a court ruling that forced Apple to change its App Store payment policies. For the first time, players can now choose between Apple’s in-app payment system and the Epic Games Store when purchasing V-Bucks. Epic’s option opens in a browser and offers a 20% bonus incentive, a setup that was previously banned under Apple’s rules.

This return stems from a legal victory for Epic Games in its long antitrust battle with Apple, after it was initially removed in 2020 for bypassing Apple’s 30% commission. The ruling allows developers to link to external payment options and blocks Apple from applying commissions on out-of-app purchases initiated via in-app links.

Fortnite’s approval didn’t follow the usual App Store process—it came after legal pressure escalated. It quickly shot to the top of the free games chart, but its presence remains uncertain. Apple is appealing the ruling and seeking a stay that could force the game off the App Store again.

Currently, Fortnite is only available on the U.S. iOS App Store, not on Macs or in other regions via native apps. In the EU, Epic is using its own distribution methods under the Digital Markets Act. For users outside supported areas or on older hardware, cloud gaming platforms like GeForce Now remain the best option.

In short: Fortnite is back on iOS in the U.S., but its return is legally fragile and hardware-limited—Epic’s fight with Apple is far from over.
