Over millennia, architects have been motivated to produce physical models of their creations. This is obvious as various artistic renderings has been excavated at archeological sites, some of which are estimated to be thousands of years old. However, it was during the Renaissance Period when Leon Battista Alberti first documented the use of models for study and analysis. Since then, the model making methods have no doubt changed, but the premise remains the same. Luckily today, the technology exists to simply print 3D models of architecture from a digital file.
Make no mistake, while 3D printing is incredible, some effort is still required. We have not quite reached the "microwave stage" where a user can send a print and simply collect their final product --like a microwaved hot beverage. But, we are pretty close. There are a few manipulations that need to happen first.
