The building measures only 86 square feet, barely big enough for a sofa, but DUS Architects is betting it represents a method of building that is cheaper, faster and less wasteful than conventional construction.
The Urban Cabin was made from a linseed-oil based “bio-plastic” with a 3-D printer and installed as an “urban retreat” with its own tiny park and outdoor bathtub in a former industrial part of Amsterdam.
Although the cabin can be rented for short stays, no one is really going to live there. DUS Architects sees the structure as part of its ongoing research into “compact and sustainable dwelling solutions in urban environments.”
says the technology is well suited for small, temporary dwellings — in disaster areas, for example. The material can be shredded and turned into new buildings when the original structure is no longer needed.
DUS is part of the rapidly growing experimentation in 3-D printing technology that can reduce production time by 50% to 70%, labor cost by as much as 80% and construction waste by as much as 60% over conventional building, according to .
DUS also is involved in a three-year project in Amsterdam to create the , also a 3-D printed structure.
Printed buildings can be very large
The technology is not limited to tiny, experimental structures. , Construction Dive described a five-story apartment building in a Chinese industrial park created with a very large 3-D printer by WinSun Decoration Design Engineering Co. The stands next to a 1,100-square-meter mansion created entirely with a 21-foot by 33-foot printer. The mansion, as well as its contents, were made with a material blending glass fiber, steel, cement, hardening agents, and recycled construction waste.
WinSun has met with Saudi Arabian officials on a potential project to print 1.5 million homes over the next five years to address a housing shortage among middle-class citizens. Earlier this year, Dubai announced its intent to build one-quarter of all new city buildings with 3-D printing by 2030.
In the U.S., said it would begin construction next year of a futuristic single-family home picked in a design competition, the website 3ders.org reported.
Branch’s “C-Fab” technology extrudes a carbon-fiber-reinforced ABS plastic that can be covered with conventional materials, such as concrete or spray foam, according to the website.
