We have the first 3D printers back in the mid-1980s
I didn't know it was out that early.
I think 3D printing will definitely be a part of the future as it will make things easier to automate. At the same time, it should reduce the costs of things closer to the material costs since the printer will do the rest. I am very interested in how the housing market will look because 3D printed houses are way cheaper to make.
