Print Your Own House
This is cool! You've seen those “prototype machines” that build
plastic prototypes by solidifying a liquid plastic by “printing” on the
surface with a special laser? Well here's a twist on that idea: A
robot that builds a house by squirting successive layers of concrete
based on architect's plans.
As the article describes: “It takes instructions directly from an
architect's computerized drawings and then squirts successive layers of
concrete on top of one other to build up vertical walls and domed
builds excellent basic housing at low prices for deserving families,
and much of the process is based on the concept of “sweat
equity”. The families who purchase houses through Habitat (yes,
they do buy them) also must
work on their own house as well as others in order to qualify.
Something about respecting the work that went into the home…
(My father in law does a lot of good work with Habitat for
Humanity. He and several others comprise the Gray Ghosts, a volunteer group that's essential to Cobb County Habitat for Humanity).
