A 3D printing company is using technology to bring fast, flexible and affordable housing to Englewood. The company called 3D Build Systems plans to start printing homes by the summer of 2019. The printing process can assemble a home in a matter of hours. It simplifies in many ways the way we construct a wall, but we can do it very quickly and with a pattern that cant be done manually, said Don Musilli, the CEO of 3D Build Systems.
