CAPE TOWN – Imagine living in a city where if you wanted a house all you do is to print it. The Vulcan 3D printer can build one home a day at a cost of $4 000 per structure. The printer – once it has been set – squirts out the concrete material in layers to build floors and walls, which harden as it goes. The printer releases the cement as per building specification and plan of the house. The only disadvantage with the 3D printer is that it reduces the number of people that can be involved in building the house. The house built by the 3D printer requires less labour, only two to four people. Advancements in the tech sector, particularly robotics and 3D printing, should inspire the local tech community to consider the informal settlements challenge as an area that can be solved.
