I am printing a model of the house on the 3D printer. It melts PLA plastic and builds up thin layers from a computer model. PLA is made from starch, usually maize.

It is useful to turn the drawings into a physical model and get a feel for the spaces, even though the computer model already gives a fairly good impression.
