When I first started out as an architect, personal computers were just hitting the practice; small offices were just starting to give CAD (computer aided drafting/design) a try. Now, we have 3D modeling in the cloud. It's rather astonishing.
Even more astonishing, modern CAD software now outputs to 3D printers. I made this little test house to see how to link and embed a model made from geometric primitives in Tinkercad. I then exported the model as an .stl file and printed it.
