Starsand Technologies co-founder Ann Dela Cruz, a native of Guam, speaks at the discussion
on 3D Printing Concrete as an affordable solution to Guam’s housing needs. More than
100 people attended the roundtable on November 7, 2023, at the School of Business
and Public Administration, University of Guam.
The University of Guam hosts a roundtable about 3D Printing as a solution to Guam’s
affordable housing challenge. Industry experts on 3D printing concrete houses were
featured at the roundtable on November 13, 2023. Speaking is Dr. Ernesto Guades, Assistant
Professor at the School of Engineering, who discussed initial research at UOG to recycle
demolished concrete into sand and gravel for pavements and other non-structural uses.
With Guam experiencing a shortage of affordable houses, the University of Guam recently
hosted a roundtable discussion about a potential housing solution that will be quicker
than traditional builds, and potentially cost-effective.
The solution? Using robots to build concrete homes. It’s not as futuristic as it sounds.
Commonly called 3D concrete printing, the technology has led to the development of
3D printed concrete houses in parts of the United States, Japan and Germany, among
“Solving Guam’s housing affordability challenges will result in more Guam families
staying on the island instead of leaving for more affordable cost of living in the
continental United States,” said UOG President Anita Borja Enriquez, as she welcomed
more than 100 guests who attended the roundtable on November 17 at the School of Business
and Public Administration.
Dr. Ernesto Guades, Assistant Professor at the University of Guam School of Engineering,
also presented research at the School of Engineering to reuse old concrete waste from
demolished buildings and recycle them for gravel and sand that can be used for paving
and other construction projects.
The roundtable, organized by UOG’s Office of Research and Sponsored Programs (ORSP),
offered perspectives from experts who are already in the business of either printing
concrete homes or using 3D technology to manufacturer on-demand parts for businesses
and the military.
James Lyman, CEO of Mudbots 3D Concrete Printers USA, which offers concrete printers
that can build tiny homes to customs homes and industrial buildings, said 3D concrete printing technology can significantly reduce the cost of construction
because of savings in time, materials and labor, among other factors.
Adrian Sinclair, co-founder of Starsand Technologies, an angel investor who also is
involved as a civilian innovator at YokoWerx, an Air Force innovation lab, saw the potential for the technology to work
Sinclair partnered with Starsand Technologies co-founder Ann Dela Cruz, a Guam native,
Army veteran and real estate businesswoman who came back to the island after having
been away for 25 years. Called home to help with her family’s business succession,
she got drawn to helping find an affordable housing solution for Guam residents.
“I found myself asking this question: Is it possible that additive construction, which
is a fancy term for 3D concrete printing, can be a solution to our affordable housing
crisis? And if so, what are the next steps?” Dela Cruz said. Community engagement
was one of them.
Dela Cruz had a meeting with Dr. Pamela Peralta, UOG Interim Vice Provost, Research
and Sponsored Programs, which led to the University hosting the roundtable.
There are issues to overcome, including convincing banks and other lenders, home insurance
companies and government regulators, according to affordable housing proponents at
Proponents of affordable housing expressed optimism that further community discussions
will lead to resolving the challenges.
