More 3-D printing please! You asked for more and they answered. An architectural firm in Amsterdam is working on the “3-D Print Canal House,” a project using an open-source, large-scale printer called the KamerMaker (“room-builder” in Dutch) to construct an entire house and furniture.

Dus Architects’ 3-D printed house will have 13 rooms and will use concrete only for the foundation. The KamerMaker will layer thick lines of molten plastic on top of one another according to the computerized plans. The initial project started in 2013, when a small-scale model was printed. Now, the 20-foot 3D printing machine has been moved to the house’s ultimate location in Amsterdam and has begun printing full-scale wall panels and innovative furniture for a traditional-style Amsterdam canal house. Actual printing began in January and has continued to show great improvements.

Each honeycomb-structured panel takes about one week to form. The material being used is a bio-based hot melt plastic from Henkel. Scientists are testing different samples of materials to create but the final ‘hot melt’ product will be 80 percent natural – it’s a bioplastic mix made up of microfibers and plant oil.

Large pieces – like the corners – will be constructed like Lego bricks and stacked on top of one another to make the house. Each room was designed with unique features that will be designed separately on site, before being assembled into the house, so experts can test their safety.
