A Chinese R&D shop has 3D printed 10 buildings' worth of prefab slabs using enormous fused deposition modelling printers that extrude concrete.
The prefab slabs were printed in one day, and will be fitted together at the site itself. Each building's slabs cost about $5000.
Like their desktop counterparts, the construction-grade WinSun 3D printers use a fused deposition modeling (FDM) technology to deposit materials one layer at a time in a process that's similar to squeezing frosting from a pastry bag.
Using a CAD design as a template, a computer controls a mechanical extruder arm to lay down concrete, which is treated with special hardeners so that each layer is strong enough to support the next.
The buildings are constructed in parts inside a Yingchuang New Materials factory, one wall at a time. The pieces are subsequently joined together at a construction site.

3D printing reaches new heights with this ingenious robotic salad-tossing machine. This pre-programmed beauty has three modes of operation, one of which will surely match how you like getting your salad tossed.
The microgravity of space would really put a damper on your dice games. You roll them and they don’t land. The 3D Printing Professor has a fun solution. Space Dice (via Adafruit)
Gilles Retsin has been experimenting with 3D-printed design concepts, but he’s also been working with computational mereology to engage in large-scale discrete fabrication. Think of it like Tetris or LEGO: a set of prefabbed interlocking parts that can then be assembled by a robot programmed to create a specific shape.

Although there will never be a consensus about the best way to make coffee, any coffee connoisseur will agree that controlling the grind of your beans and balancing water temperature are the keys to a tasty cup. Since your plastic coffee pot doesn’t really allow for that kind of customization, going back to the French […]
