Imagine if you could build a house in as little as a day,
with almost no construction crew.
The 3D printer is poised to make that happen.
Architects, artists, designers and scientists are figuring
out ways to use the budding technology to make building homes faster, easier
and cheaper. While none of the prominent 3D projects are fully finished, some
are starting to rise off the ground, layer by layer.
The process works similar to any other 3D printer, only
instead of a printer roughly the size of a microwave, it's the size of a
building.
The homes are first designed using 3D modeling software,
which uses a code to tell the printer where to move when printing the object's
layers. It is capable of taking into account gaps for things such as windows,
plumbing, insulation and electrical wiring.
Then, a variety of materials -- from plastics to concrete to
recycled construction materials -- are heated until they become liquids, then
printed out layer after layer, to form the structure, as well as various other
parts. The parts are put together, along with more common construction elements
such as windows and doors, to make a completed building.
A few drawbacks exist, namely that these are new structures
and so they are untested as far as structural integrity goes. There are still
questions surrounding things such as material health, fireproofing, wind loads,
foundations, insulation and longevity.

projects that are piquing interest around the world.
