University of Maine Advanced Structures and Composites Center’s bio-based 3D printed tiny home.

The University of Maine’s Advanced Structures and Composites Center 3D printed a 600-square-foot tiny home.
ASCC encapsulated wood waste from local sawmills in a bio-resin to create a durable printing material.
Take a look around the home’s bathroom, living room, bedroom, and kitchen.
Maine is now home to one of the country’s newest 3D-printed homes.

But unlike other printed units, this 600-square-foot tiny home is fully recyclable.

Homes both big and small built using concrete and 3D printers have been popping up around the world at an increasing rate.

The tech is scaling rapidly as more companies enter the construction-tech space.
University of Maine
But only a handful of startups and people are taking an even more novel approach to this new construction method by printing with non-concrete materials.
University of Maine
And surprisingly, a university is one of them.
University of Maine
Say goodbye to concrete mixes and hello to wood residuals and bio-resins.

The University of Maine’s Advanced Structures and Composites Center has taken a new approach to the tech by using a proprietary bio-based material to print the floors, walls, and roof of a 600-square-foot home.University of Maine Advanced Structures and Composites Center’s bio-based 3D printed tiny home.

And if it wanted to, ASCC says it could fully recycle the home’s printed components.

“We’re looking at the ability to 100% recycle the home materials five times and we’re doing testing right now to see what happens every time you recycle it,” Habib Dagher told Insider.
University of Maine
Dagher — ASCC’s founding executive director and principal investigator of this project — hopes this home is proof that the tech could help sustainably alleviate our country’s ongoing affordable housing crisis.

… creating a durable printing material that could be immune to supply chain fluctuations while a giving second life to what would otherwise be wood waste.
University of Maine
And the supply is nearly as endless as the current demand: Dagher believes the state produces enough wood waste to make 100,000 homes annually.

So when the housing crisis hit, construction costs started skyrocketing, and materials and labor became harder to access, the team wanted to see if they could use it to print homes.
University of Maine
“We’ve been looking for ways to reduce the cost [of building], increase [housing] availability, and build houses that are more sustainable over the long run,” Dagher told Insider.
University of Maine
Many advocates of 3D printers believe the tech has major benefits over traditional construction.
University of Maine
Because the printer is programmed to be precise, there was almost no construction waste and less physical labor required to build this tiny home.
University of Maine
And printers work faster than humans, increasing construction speeds with the potential of slashing costs as this tech continues to become more common.
University of Maine
These are certainly big benefits at a time when Maine is facing an “unsustainable” affordable housing crisis, Dagher said.
University of Maine
So unsurprisingly, this home could serve as an innovative way to alleviate said problems.
University of Maine
But the home doesn’t look as futuristic as you might expect.

The printed walls and ceiling look layered as seen below, a signature of the 3D printer.

By using this tech, the team was able to curve the home’s walls into the ceiling.

And instead of the drab grey-toned walls common in concrete printed homes, these walls look more wood-toned.

Besides its unique appearance, the 600-square-foot unit has the same functions as any traditional home.

And all of these rooms look as luxurious as any contemporary traditionally built home.

Many big 3D printing construction projects happen on-site.
University of Maine
But this home was instead prefabricated and printed off-site using ASCC’s proprietary printer, which Dagher says is the world’s largest polymer 3D printer.
University of Maine
And it wasn’t printed in one piece.
University of Maine
Instead, the home is made up of four approximately 200-square-foot modules.
University of Maine
These four insulated and pre-wired pieces were then moved to an on-site concrete foundation using a flatbed truck.
University of Maine
It only took half a day, a crane, bolts, and connectors to assemble the four modules into a home.
University of Maine
And the electrician spent an additional two hours powering the unit.
University of Maine
Now, it’s a fully functioning house with a unique construction backstory.
University of Maine
The team is now collecting data on its performance to determine what could be improved in the next printed home.
University of Maine
The goal is to produce one of these units in about 48 hours.
University of Maine
But this home took about 10 times longer, Dagher said.
University of Maine
The team is now designing a factory to grow the production of these recyclable homes.
University of Maine
And it has already raised over $80 million to build this manufacturing space.
University of Maine
So if the team’s future plans come to fruition, you could see a full neighborhood of recycled homes sooner than you’d think.
University of Maine
But that’s not to say concrete homes don’t have their place in the future. After all, the unifying goal is to grow housing production.
University of Maine
“We’re in a crisis mode right now,” Dagher said. “Anything we can do to increase the output of homes, whether it’s concrete or bio-based 3D printing or other technologies, is a good thing.”
