3D printer builds houses in 24 hours

Each house costs around US$ 4,000 and has floor area of up to 72 m2. One of these 3D printed houses is alreay in use in Austin, Texas, and whole block is scheduled to be printed in El Salvador in 2019

According to UN estimates, by 2030, more than 3 billion people could be homeless - today, 1,2 billion already live in this situation. This global house shortage drove companies like "ICON" and "New Story" to act. They developed a 3D printer that uses concrete as 'ink' and prints 2-bedroom homes of up to 74 m2 in less than 24 hours for US$ 4,000. One of these 3D printed houses is alreay in use in Austin, Texas, and whole block is scheduled to be printed in El Salvador, in 2019.
