The world's largest 3D printer is at a university in Maine. It just unveiled an even bigger one
ORONO, Maine (AP) — 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." There could be even larger printers after the University of Maine breaks ground this summer on a new building, a spokesperson said.
The massive printer “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,” said Habib Dagher, director of UMaine’s Advanced Structures & Composite Center, where both of the printers are located.
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, under secretary of defense for research and engineering, said the printer "stands as a beacon of innovation."
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.
