Built inside a 20-foot shipping container placed on its end, the Kamermaker – ” room maker” in Dutch – is one of the largest 3D printers we’ve ever seen. Able to print objects as big as 2 meter square and 3.5 meters high, the Kamermaker is designed to print huge objects including furniture, architectural elements, and even entire rooms.

The Kamermaker is a collaboration between Architectburo DUS and Utilimaker and the result of wanting to build the world’s largest 3D printer pavilion. Built inside a stainless steel-clad shipping container, the Kamermaker features a scaled-up version of the X, Y, and Z axes you’d find in any other 3D printer. The only change is a scaling up of current designs, allowing it to print small wind turbines covering its surface or, theoretically, a life-size TARDIS.

Because using traditional plastic filament would be prohibitively expensive, the Utilimaker team chose to extrude plastic pellets on the fly as it is used. There’s an excellent video of the filament extruder here along with a walk-through of the machine in operation after the break.
