Wikipedia describes human scale as the set of physical qualities, and quantities of information, characterizing the human body, its motor, sensory, or mental capabilities, and human social institutions. In terms of distance it is between one to two meters.
From the onset, the cost of printing objects in human scale has been out of the reach of most humans. For 3D printing to become the revolution that so many claim, printers need to build objects that are useful in every day life; human scale as it called.
This is the realm of large format 3D printers.
3D printing architectural models is fine for visualization, but there needs to be more 3D printing in architecture and construction. Ultimately, the cost has to come down and the capabilities need to go up for the technology to become common place.
The objective is to present mechanisms and designs that have scalability as their primary goal. To take 3D printers from the cubic foot to the cubic meter and beyond!
