Part 2: A selection of the most exciting 3D printed mansion, house and apartment projects.Part 1: Five key advantages of 3D printed houses, and how 3D printed buildings would benefit us.We have divided this complete guide to 3D printed houses into three parts: We will be showcasing some interesting 3D printed house projects that already exist, the advantages and disadvantages of 3D printed houses, and mentioning some 3D printer companies who are working hard to commercialize the tech. We also have a ranking of the most innovative house 3D printer companiesģD printing offers the chance to build houses faster, more accurately and cheaper than ever before.These gigantic 3D printers can build an entire 3D printed house in just hours!
