The same company known for printing 10 home in less than 24 hours is back with a new record-breaking construction project: a multistory apartment structure built using recycled building materials and fast-hardening cement, paired with an ornate villa assembled using the same technologies.
Construction waste forms the aggregate base of WinSun‘s quick-drying concrete, while a huge 3D printer array is responsible for building the large prefabricated parts that are then built on site with steel reinforcement and regulation insulation.
In a twist that will able to those who enjoy truth in architecture, much of the extrusion process is evident on the interior and exterior walls of the villa component as well.
Drawing on CAD files, the printer lays out the pattern like a cake decorator squeezes out frosting, creating space-frame gaps for insulating materials, plumbing and electrical – a high-tech process to quickly create a pair of low- and mid-rise buildings.
According to WinSun, “This process saves between 30 and 60 percent of construction waste, and can decrease production times by between 50 and 70 percent, and labour costs by between 50 and 80 percent. In all, the villa costs around $161,000 to build.”
While the company has yet to reveal just how big of a structure they can build using their existing equipment, their future goals include larger buildings, perhaps even prefab skyscrapers, and possibly bridges or other infrastructure. From 3Ders, “Today’s press conference attracted more than 300 building industry experts, investment bankers as well as media reporters. Ma Yi He, CEO of WinSun explained: the company’s success is due to their unique and leading techniques. First is their exclusive 3D printing ‘ink,’ which is a mixture of recycled construction waste, glass fiber, steel, cement and special additives. According to Ma, waste from recycling construction and mine rest produces a lot of carbon emissions, but with 3D printing, the company has turned that waste into brand new building materials. This process also means that construction workers are at less risk of coming into contact with hazardous materials or work environments.”
