Lib Work's latest project, Model B, is a single-story, 1,076-square-meter house. Its construction was primarily made from soil, lime, and natural fibers. According to the company, the new production process significantly reduces carbon emissions. Furthermore, the house is five times more durable than previous designs that used cement.

3D PRINTING WITH WASP

According to Popsci, the shell of the house, built in Kumamoto, Japan, was created using a specialized system installed on-site by Italian 3D printing firm World's Advanced Saving Project (WASP). It used an earth-based composite material and a predetermined design plan. Once the printing process was complete, the shell was coated with a protective coating, and doors, windows, and plumbing were installed.

The Model B is completely off-grid. It's equipped with solar panels, a battery storage system, energy-efficient air conditioning, lighting, and water heating systems. Its interior features a modern, light-filled design, featuring a flat roof and corrugated walls, typical of 3D printing.

MATERIALS RETURNING TO NATURE

During the prototype's testing phase, sensors placed in the walls measure humidity, insulation, and structural strength. Unlike traditional houses, Model B is designed to be dismantled and returned to nature. Most of the materials used are biodegradable and avoid ending up in landfills.

While it's still early days for fully 3D-printed neighborhoods, Lib Work announced it will open pre-orders for the Model B in August.
