3D printing has come a long way since the 1980s. The first machines, which used a method called Stereolithography, were designed by a man called Charles W. Hull and cost in the realm of $100,000.

Today, you can buy a home 3D printer for less than $150, and cutting edge industrial printers can print in titanium, concrete, wood and even “meat”.

What a time to be alive. Optimistically, 3D printing could be a solution to some of the world’s most pressing problems, from the need for sustainable food to mass homelessness. The potential disruptions to industries like manufacturing and construction are radical, and the science is advancing faster than the world’s first completely 3D printed supercar.
