Concrete may seem strong and permanent, but it can be surprisingly vulnerable to the elements. Now researchers at Drexel University have demonstrated a type of self-healing concrete embedded with “BioFibers” that use bacteria to patch up cracks as they form.
UP MTech student Ramansh Bajpai created a ‘transparent’ concrete which is 23% stronger, 15% lighter and free from carbon dioxide! It is also much cheaper and can reduce electricty use by 30%.
You just need a scaled-down cut-out image of the building from above, then use a guide to follow the shape of the jig – to allow the material to fall in the right place, you could even sell lots of 1-metre square jigs of different shapes of a building, for example, the castle.

INTRODUCING BOD2
BOD2 is an upgraded and improved version of the printer which
was used to 3D print the first building in Europe, The BOD.
Based on the experience obtained with the BOD printer, the BOD2 incorporates improved functionality and stability compared to the first version. It is ... Read more

Think big – this is huge, could work for building schools and hospitals in unlucky countries…
This can print a house for 4 grand. But the machine is so expensive that its no use to those who need housing the most.
