By industry
What construction owners and operators have put into production, what it cost and what went wrong.
This page covers how buildings and their materials are being made differently: robotic 3D concrete printing, AI-screened and lower-carbon cement, and the money that pays for it, or stops paying for it.
Printing has reached military scale. ICON says it printed ten barracks buildings at Fort Bliss to house up to 560 service members, on a $62.8 million contract. [1] The industry has also had failures: after an assignment for the benefit of creditors, the assignee for 3D-printing builder Mighty Buildings said nothing was left for unsecured creditors or shareholders. [2]
Cement is the bigger carbon problem. MIT researchers used language models to pull materials data from 88,000 papers in search of cement substitutes. That's a modeled screen, not yet a lab result. [3] Heidelberg Materials says its Brevik, Norway, capture plant will take about 400,000 tonnes of CO₂ a year, half the plant's emissions, a company figure. [4]
Policy can reverse fast. In May 2025 the Energy Department cancelled 24 awards it put at over $3.7 billion, including clean-cement grants to Sublime and Brimstone. [5]
Earlier cases here follow Rosendin's solar-panel robot from field trials to sale and to a solar tracker maker that took its patents.
Each case below covers what was built, what it cost where disclosed, and what went wrong.

The Cambridge spinout says its process makes clinker in the electric arc furnaces that recycle steel, with no kiln or quarried limestone. Its investors expect an immediate 50% emissions cut at cost parity.
A trade article says contractors have completed five 3D-printed Walmart additions in four states, and FMGI says its projects cut costs about 15%. Walmart itself hasn't said anything we could find.
ICON printed ten buildings for 560 troops in 58 days on a $62.8 million contract. ICON's release puts the savings at $5.2 million total and $5.6 million in overhead, and the sources give six, seven or nine months for the schedule.
The Colorado startup's 240,000-ton Cleburne plant is still under construction. Terra claims it is on schedule and within budget but gave no budget, and its full cement replacement is still in trials.
Public patent records show Rosendin signed its robot patents over to ULC Technologies in June 2025. In February 2026, ULC assigned them, plus three related applications, to Nextpower, the company formerly called Nextracker. Nobody has announced a deal.
Amrize estimates the mix cuts the concrete's carbon footprint by 35%. Meta later said it reached full strength 43% faster. Both are company figures.
After paying senior secured lenders, the assignee says it has no assets left for anyone else. The documents give no dollar figures.
3DCP Group printed 36 student apartments in Holstebro with a three-person crew, COBOD says. Neither company published a cost.
The Canadian company claims more than 690,000 tonnes of CO₂ kept out of the air across more than two dozen countries. It gave no audit, and its release doesn't break the figure down.
The 40 m² Ong Ang bridge was printed off-site in 19 segments and craned in within a day, its designers say. No cost was published.
About 5 cubic metres of the material could cover an average home's daily needs, down from 45 in 2023, MIT says. It's still a lab prototype, and batteries remain denser.
The Norway facility is designed to capture about 400,000 tonnes of CO₂ a year, half the plant's emissions, the company says. First evoZero deliveries went to an Oslo station and a 3D-printed housing project.
The 9th Engineer Support Battalion says it can print ramps, barriers and makeshift railheads. Nobody has published what the printing costs.
The deal provides for a first plant making Fortera's ReAct cement at a Graymont site and a framework for more, the companies' lawyers say. Fortera claims its process cuts CO₂ by 70%. No site, cost or schedule was given.
The Tapping house still took five months from slab to finish. The saving Contec claims is on the structural walls.
The contractor says the robot halved a setting crew, at somewhat lower output, and cut panel breakage to "virtually zero." It also calls the machine a "working prototype," and building robots isn't its business.
PERI 3D Construction built the 1,400 sq ft store with printer maker COBOD. A state filing puts the estimated cost at $1,198,000; there's no comparison to a conventional store.
The team's model suggests that construction waste and incinerator ash could, in theory, replace half of global cement. It's a modeled estimate; lab validation is still to come.
Four cement projects worth about $1.28 billion were among 24 awards totaling over $3.7 billion that DOE terminated. E&E News reported that only $99 million had been paid out.
The binding deal runs six to nine years and lets Microsoft buy the cement's environmental attributes separately from the material, the companies said. No price was disclosed.
The Wolf Ranch community in Georgetown, Texas, is the world's largest 3D-printed community, CNBC reported. Lennar's chairman says the first try cost a bit more than planned.
Serendix says it assembled the new Hatsushima station for JR West in about two hours after the 11:57 p.m. train. It didn't say what it cost.
Rosendin and ULC Technologies spent a year and a half developing a three-robot system, ENR reports, and it has had a year of field trials. Its SVP says the crew got smaller and the robot works. He also says the most expensive part was overbuilt.
Three printed buildings, two in Texas and one in New Mexico, each house up to 56 soldiers. The Army didn't publish what they cost.
Louth County Council's three Grange Close houses were printed in 12 days. The builder says each cost about €253,000 before VAT, the same as conventional construction.
SQ4D printed more than half of the Brentwood house. Because the method was new, Habitat couldn't use its usual grants, and the town put in $250,000.
Six families got keys to the Lünen building, where rent is capped at €6 per square metre. The printer ran for 118 hours.
Microsoft estimates the hybrid timber, steel and concrete design cuts embodied carbon by 35% versus steel and 65% versus precast concrete. No project cost was given.
