Here's a project that could pave way to structures both unique and affordable. A team of researchers from the UC Berkeley's College of Environmental Design has unveiled the Bloom Pavilion, which they call "the first and largest powder-based 3D-printed cement structure." It measures 9 feet high, 12 feet wide and 12 feet deep, with a traditional Thai floral motif design. The pavilion is not the first 3D-printed building, to be clear. A Chinese company built 10 houses in under 24 hours last year and finished a whopping 5-storey apartment block in January using 3D-printed parts. Plus, there's that 3D-printed castle in Minnesota. However, it was created using dry powdered cement, whereas other 3D-printed buildings were made by extruding wet cement through a nozzle.
