With these advances in technology and the advent of 3D printing, it has now become possible to print a building – a development that’s caused a stir in the construction business for various reasons, including potential disruptions in multiple global supply chains.

Known in the trade as “additive manufacturing”, 3D printing was first developed in the 1980s. Due to more sophisticated types of printers, we can now print things like houses, clothes and spare parts for planes. Artificial limbs and internal organs are also among the latest list of uses for 3D printing.
