World’s biggest 3D printer unveiled in Maine may one day create entire neighborhoods
ORONO, Maine – The world’s largest 3D printer has created a house that can cut construction time and labor. An even larger printer unveiled on Tuesday may one day create entire neighborhoods.
The machine revealed Tuesday at the University of Maine is four times larger than the first one — commissioned less than five years ago — and capable of printing ever mightier objects. That includes scaling up its 3D-printed home technology using bio-based materials to eventually demonstrate how printed neighborhoods can offer an avenue to affordable housing to address homelessness in the region.
Thermoplastic polymers are extruded from a printer dubbed the “Factory of the Future 1.0,” said Habib Dagher, director of UMaine’s Advanced Structures & Composite Center, where both of the current printers are located. It combines robotics operations with new sensors, high-performance computing and artificial intelligence, Dagher said.
And there could be even larger printers in the future after the University of Maine breaks ground this summer on a new building.
“We’re learning from this to design the next one,” he said.
3D printer a “beacon of innovation”
Those attending the event included representatives from departments of defense, energy and housing, as well as other stakeholders who plan to utilize the new technologies made available by the printer. Heidi Shyu, undersecretary of defense for research and engineering, said the printer exceeded her expectations and “stands as a beacon of innovation.”
Shrouded by a black curtain, the printer was on and whirring behind the speakers during the event. At the end, the curtain opened revealing the printer was working on a test project for a future boat.
The printer’s frame fills up the large building in which it’s housed on the UMaine campus, and can print objects 96 feet long by 32 feet wide by 18 feet high (29 meters by 10 meters by 5.5 meters).
It has a voracious appetite, consuming as much as 500 pounds (227 kilograms) of material per hour.
Building homes with a 3D printer
The original printer, christened in 2019, was certified by Guinness World Records as the world’s largest polymer 3D printer, the university said. It was used to create a 600-square-foot, single-family home made of wood fiber and bio-resin materials that are recyclable. Dubbed “BioHome3D,” it showed an ability to quickly produce homes. To meet the growing demand for housing, Maine alone will need another 80,000 homes over the next six years, according to MaineHousing.
Dagher said there’s a shortage of both affordable housing and workers to build homes. The university wants to show how homes can be constructed nearly entirely by a printer with a lower carbon footprint. The buildings and construction sector accounts for roughly 37% of global greenhouse gas emissions, largely due to the production and use of materials such as cement, steel and aluminum that have a significant carbon footprint, according to the United Nations Environment Programme.
Such printed buildings can be recycled, which is unique compared to current construction. “You can basically deconstruct it, you can grind it up if you wish, the 3D printed parts, and reprint with them, do it again,” Dagher said before the event.
“It’s not about building a cheap house or a biohome,” he added, referring to the first 3D-printed house made entirely with bio-based materials. “We wanted to build a house that people would say, ‘Wow, I really want to live there.’”
Future plans for 3D printing
The Army Corps of Engineers provided most of the funding for the new printer, which cost several million dollars, said Dannel Malloy, chancellor of the University of Maine System. It was built by the university in collaboration with Ingersoll Rand for construction of the printer and Somatex for the supporting structure, officials said.
Looking ahead, researchers plan to tinker with the material consumed by the machine, including more bio-based feedstocks from wood residuals that are abundant in Maine, the nation’s most heavily forested state.
But it can be used for a variety of other creations and already has been used for a range of things, from boats to defense department structures. In the past, the university showed off a 25-foot boat created by the first printer. Upcoming projects with the new printer include a 50-foot boat and houses to serve homeless people, Dagher said.
As for the original 3D printer, it isn’t going away. The two printers can be used in concert to streamline manufacturing by working on the same project — or even part if necessary — and there will be even more of them working together in the future, officials said.

NECEC conservation plan will not protect Maine’s mature forests | Opinion
Robert Bryan is a licensed forester from Harpswell and author or co-author of numerous publications on managing forests for wildlife. Paul Larrivee is a licensed forester from New Gloucester who manages both private and public lands, and a former Maine Forest Service forester.
In November 2025, the Department of Environmental Protection (DEP) approved a conservation plan and forest management plan as mitigation for impacts from the NECEC transmission corridor that runs from the Quebec border 53 miles to central Maine.
As professional foresters, we were astonished by the lack of scientific credibility in the definition of “mature forest habitat” that was approved by DEP, and the business-as-usual commercial forestry proposed for over 80% of the conservation area.
The DEP’s approval requires NECEC to establish and protect 50,000 acres to be managed for mature-forest wildlife species and wildlife travel corridors along riparian areas and between mature forest habitats. The conservation plan will establish an area adjacent to the new transmission corridor to be protected under a conservation easement held by the state. Under this plan, 50% of the area will be managed as mature forest habitat.
Under the forest management plan, a typical even-aged stand will qualify as “mature forest habitat” once 50 feet tall, which is only about 50 years old. These stands will lack large trees that provide wildlife denning and nesting sites, multiple vegetation layers that mature-forest birds use for nesting and feeding habitats and large decaying trees and downed logs that provide habitat for insects, fungi and small mammals, which in turn benefit larger predators.
Another major concern is that contrary to the earlier DEP order, the final approval allows standard sustainable forestry operations on the 84% of the forest located outside the stream buffers and special habitats. These stands may be harvested as soon as they achieve the “mature forest habitat” definition, as long as 50% of the conserved land is maintained as “mature.”
After the mature forest goal is reached, clearcutting or other heavy harvesting could occur on thousands of acres every 10 years. Because the landowner — Weyerhaeuser — owns several hundred thousand acres in the vicinity, any reductions in harvesting within the conservation area can simply be offset by cutting more heavily nearby. As a result, the net
mature-forest benefit of the conservation area will be close to zero.
Third, because some mature stands will be cut before the 50% mature forest goal is reached, it will take 40 years — longer than necessary — to reach the goal.
In the near future the Board of Environmental Protection (BEP) will consider an appeal from environmental organizations of the plan approval. To ensure that ecologically mature forest develops in a manner that meets the intent of the DEP/BEP orders, several things need to change.
First and most important, to ensure that characteristics of mature forest habitat have time to develop it is critical that the definition include clear requirements for the minimum number of large-diameter (hence more mature) trees, adjusted by forest type. At least half the stocking of an area of mature forest habitat should be in trees at least 10 inches in diameter, and at least 20% of stands beyond the riparian buffers should have half the stocking in trees greater than or equal to 16 inches in diameter.
Current research as well as guidelines for defining ecologically mature forests, such as those in Maine Audubon’s Forestry for Maine Birds, should be followed.
Second, limits should be placed on the size and distribution of clearcut or “shelterwood” harvest patches so that even-aged harvests are similar in size to those created by typical natural forest disturbance patterns. These changes will help ensure that the mature-forest block and connectivity requirements of the orders are met.
Third, because the forest impacts have already occurred, no cutting should be allowed in the few stands that meet or exceed the DEP-approved definition — which needs to be revised as described above — until the 50% or greater mature-forest goal is reached.
If allowed to stand, the definitions and management described in the forest management plan would set a terrible precedent for conserving mature forests in Maine. The BEP should uphold the appeal and establish standards for truly mature forest habitat.
