World's Largest 3D Printer Constructs Homes—A Larger One Was Just Unveiled in Maine


The world’s largest 3D printer has successfully constructed a house, showcasing its potential to streamline construction processes by reducing time and labor. 

Meanwhile, an even larger printer was recently unveiled in Maine, suggesting the possibility of constructing entire neighborhoods.

The University of Maine (UMaine) recently unveiled a new 3D printer, known as the Factory of the Future 1.0 (FoF 1.0), at the Advanced Structures and Composites Center (ASCC).

This printer, surpassing its predecessor in size, aims to advance sustainable manufacturing across various industries.

FoF 1.0 can print objects as large as 96 feet long by 32 feet wide by 18 feet high, with a printing speed of up to 500 pounds per hour.

This printer utilizes thermoplastic polymer and offers promising opportunities for eco-friendly and cost-effective manufacturing. It could be used in industries such as national security, affordable housing, bridge construction, and maritime vessel fabrication.

Substantial support from the Office of the Secretary of Defense through the U.S. Army Corps of Engineers made the development and fabrication of FoF 1.0 possible. 

It is designed not only as a large-scale printer but also as a versatile system capable of dynamically switching between various manufacturing processes, including additive manufacturing, subtractive manufacturing, continuous tape layup, and robotic arm operations.

New Research Frontiers

FoF 1.0’s capabilities extend beyond traditional manufacturing processes, offering new research opportunities in collaborative robotics operations, sensor integration, high-performance computing, and artificial intelligence.

These advancements are expected to meet rigorous quality standards and drive innovation across multiple sectors.

“FoF 1.0 opens up new research frontiers to integrate these collaborative robotics operations at a very large scale with new sensors, high-performance computing and artificial intelligence to create born-certified systems that meet high quality standards,” ASCC Executive Director Habib Dagher said in a press release statement.

The printer’s potential extends to developing biobased feedstocks from Maine’s abundant wood residuals. Initiatives such as BioHome3D aim to leverage this technology to create sustainable and affordable housing solutions while advancing lightweight structures and vessel technologies crucial for national security.

“Maine needs an estimated 80,000 additional homes by 2030, many specifically for households with incomes at or below the area median income.

This new technology allows UMaine-ASCC to scale up its research and production of its innovative biobased 3D printed home technology,” said MaineHousing’s Development Director Mark Wiesendanger. 

“This effort creates another means of producing quality affordable housing, while further driving costs down, and using abundant wood residuals from Maine’s sawmills.”

‘Not only with tears, but with action’: Maine DOT honors two workers killed on duty

‘Not only with tears, but with action’: Maine DOT honors two workers killed on duty


AUGUSTA, Maine (WABI) – An emotional day from Fairfield to Augusta, but felt throughout Maine and beyond, as state officials, community members and loved ones honored the lives of two Department of Transportation workers who tragically died in the field.

Maine DOT Commissioner Dale Doughty described the accident as “the nightmare that commissioners worry about.”

While working on Interstate 95 in January, Maine DOT workers James “Jimmy” Brown, 60, and Dwayne Campbell, 51, died after a driver failed to brake at a stop sign and crashed into a tractor-trailer traveling on the highway.

To honor the men’s commitment to public service and their legacy as fathers, outdoorsmen and Mainers, a procession including DOT officials, family members and more traveled to the Augusta Civic Center Saturday for a memorial service.

Among those in attendance was Gov. Janet Mills, who remarked on who Brown and Campbell were and their dedication to their profession.

“Jimmy, as you know, worked for the Maine Department of Transportation for 12 years. Dwayne for more than 23 years,” Mills described. “We could count on Jimmy and Dwayne just as we could count on the 1,600 Maine dot workers who keep our roads and bridges safe every day.”

Brown was known for his humor and love of fishing, cars and his children.

Campbell got his start in the DOT by following in his father’s footsteps. Mills said at the service that Campbell loved his daughters and time spent outdoors.

For Commissioner Doughty, losses like this hit hard because of the closely bonded “family business” that DOT is.

That family expands past state lines, as departments of transportation from New Hampshire and Vermont were present to show their support.

New Hampshire DOT State Maintenance Engineer Alan Hanscom said he called Maine DOT just hours after hearing of the accident to see what his crews could do to help.

“My employees are impacted or subject to the same dangers that Maine and every other state is,” Hanscom said of the importance of his attendance. “I have an employee that was killed in a motor vehicle crash some years ago, so it kind of hits home.”

Unfortunately, Doughty says accidents happen “quite frequently.”

Saturday’s event served not only as a commemoration but also as a call to action. Despite DOT’s training, Doughty says it is rendered useless if motorists put right-of-way employees in danger through reckless or distracted driving.

Hanscom expanded: “People don’t realize that this is our office. You’re driving through our office space. We’d like you to give us some consideration and slow down and be mindful of where we are. Give us a little respect.”

Doughty mentioned that these dangers extend beyond DOT workers to everyone who does roadside work. Because of this, he says, agencies must join forces to develop solutions.

“I really think it’s time, and we have a meeting coming up in April, where we pull all agencies and all companies that work in the right-of-way, contractors, utilities, everyone to start to talk about that message,” Doughty said.

On the podium, Doughty told audiences: “Please help us carry forward their memory, not only with tears, but with action.”

On Thursday, the Joint Standing Committee on Transportation authorized the Maine Turnpike Authority to conduct a pilot program for speed enforcement in work zones. The legislation is now headed to the House and Senate.

Northern Maine Med Center RNs reaffirm care for community

Northern Maine Med Center RNs reaffirm care for community


Despite retaliation from their employer, nurses affirm their commitment to their patients and their union

Over two years since Northern Maine Medical Center (NMMC) first formed their union and began bargaining in good faith for a first contract, nurses remain committed to the patients they serve, and to making their hospital the best place it can be for everyone. Union nurses at NMMC signed the letter they released today, which says in part:

“Over the past two years, you have no doubt heard about the conflict that has grown between the hospital and us.

We want you to know that we never asked for this fight. The initiative to organize our union was to protect ourselves and our patients, not to punish any individuals or the hospital as a whole.”

The nurses’ letter goes on to say that their immediate goals as a union include: winning safe staffing for nurses and patients, promoting transparency and accountability at NMMC, retaining our local providers and staff, and making their hospital sustainable for the long term.

Terry Caron, RN and member of the nurses’ bargaining team said: “Two years ago, we decided to have a voice for ourselves and our patients by forming our union. The NMMC administration could have met us halfway, but it did not. It has only fought us and tried to punish us for speaking up. But we are as committed to our goals as ever. We will never stop fighting for our patients.”

NMMC nurses were joined today by Maine Senate President Mattie Daughtry, gubernatorial candidate Troy Jackson, and U.S. Senate candidate Graham Platner. They echoed the nurses’ call for NMMC CEO Jeff Zewe to stop his retaliation against the nurses and to finalize the union contract for which the nurses have been bargaining for most of the past two years. 


Maine State Nurses Association is part of National Nurses Organizing Committee, representing 4,000 nurses and other caregivers from Portland to Fort Kent. NNOC is an affiliate of National Nurses United, the largest and fastest-growing labor union of registered nurses in the United States with nearly 225,000 members nationwide.
