Dutch studio DUS Architects has joined the race to build the first 3D-printed house with plans to print a full-size canal house in Amsterdam. “KamerMaker XL, a 3.5 m tall FFF printer, made its way to the Buiksloter Canal in Amsterdam on January 6, where it’s already begun printing. The printer, more or less a large RepRap housed in a shipping container, is using a type of plastic — an 80% bio-based hotmelt, developed by German chemical company Henkel — to print pieces that will be assembled into a complete house.
The project’s website describes the process:
Each room is printed separately on site before being assembled into one house. This way the rooms can be carefully tested in a safe and easy accessible manner. Each room is different and consists of complex and tailormade architecture and unique design features. The structure is scripted and this creates its proper strength but also generates ornament, and allows for new types of smart features, such as angled shading scripted to the exact solar angle. Each printed room consists of several parts, which are joined together as large Lego-like blocks. Both the outside façade as the interior are printed at once, in one element. Within the 3D printed walls are spares for connecting construction, cables, pipes, communication technique, wiring etc.
The rooms themselves are entirely structurally sound. In the second phase of the project, the separate rooms are assembled into connected floors, and then stacked into the entire house. Added advantage is that the rooms can fairly easy be disconnected in case the house needs to be relocated.
DUS has already demonstrated the scale of objects that they can print, including the enormous 3D printed bench pictured below. The printing of the home and its assembly by construction company Heijmans is projected to take about three years. That gives other groups also racing to complete the “first” 3D printed building some time to enact a more efficient house printing process.(…)” http://3dprintingindustry.com/2014/01/22/worlds-first-3d-printed-house-begins-construction/
