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.

I first tried Bondic in 2015, when I ordered a tube of the UV-curing plastic and started using it to fix everything — especially irregularly-fractured items with hard-to-fill gaps.
Designer Dani Clode’s Third Thumb is a 3D printed robotic prosthetic thumb that goes on the pinky side of your hand, created a motorized, opposable additional thumb that you can use to play the guitar, pick up objects, or crack an egg.
