Contour crafting is a 3D printing technique for constructing houses and structures layer by layer under computer control. It was developed by Professor Behrokh Khoshnevis at the University of Southern California to provide quick, affordable housing. The contour crafting machine can build a 2000 square foot house in 24 hours, including plumbing and electrical systems. NASA has proposed using this technique to construct habitats for astronauts on the Moon and Mars. Contour crafting produces houses and structures much faster and more affordably than traditional construction methods, with less waste, making it useful for low-income housing and emergency shelter as well as complex architectural designs.

1. CONTOUR CRAFTING A 3-D HOUSE PRINTER

2. AIM – To study about contour crafting.
OBJECTIVES –
-To know the working process of contour crafting.
-Application and advantages of using C.C.
-Utilization of C.C machine to provide houses to slum and homeless
people .
-Provide quick shelter in case of hazard.

3. The research was started on 2004 under the a
professor “Behrokh Khoshnevis” of Southern
California university but & the whole working
project is done in 2008 & it’s come in front of the
world in 2010 when NASA have accept this proposal
to build the houses on moon & still the work is
going on.

4. Contour crafting machine is the computer control machine
which is based on layer fabrication technology &
programming based software. It is have ability to build the
G+1, 2000 ft2 house within 24 hours with the proper facility
of plumbing, electricity, & with the proper fitting of farms of
doors & window. So this is very helpful in Natural Deserter
situation for setup again the city.
At a certain range & certain elevation to craft the house

NASA's plan to build homes on the Moon: Space agency backs
3D print technology which could build base.
Technology will see lunar soil layers built up in a pre-
determined design. System will work like a giant 3D printer
using a nozzle and moveable gantry
• Creating structures in space that astronauts can live in has
become a priority for Nasa.
• With a manned mission to Mars on the agenda, and plans for
lunar exploration underway, scientists are increasingly looking
towards unconventional construction methods.
• The most promising of these is 3D printing, which could make
building a lunar home in space a matter of pressing a button and
letting a robot do the work.

10. TRADITIONAL METHOD BY PRECAST ELEMENT BY CONTOUR CRAFTING
Construction takes time
more
Comparatively less time Very lass time
Over all cost is more , very
slow process
Comparatively less Very lass time
material required is more Comparatively less Very lass time
overall project cost is more Comparatively less Very lass time

11. Due to its speed and its ability potential for immediate application in low
income housing and emergency shelter construction.
Construction of luxury structures with exotic architectural designs
involving complex curves and other geometries
The environmental impact of CC is also noteworthy.
Contour Crafting could result in little or no material waste.

12. BY USING CONTOUR CRAFTING WE CAN GIVE THE BETTER
LIFE TO SLUM PEOPLE, FARMER & THE PEOPLE SUFFERING
FROM NATURAL DISASTER AS WELL AS WHO NOT ABLE
PHYSICALLY & ECONOMICALLY SO TO PROVODE THEM
SHELTER ALL OVER THE WORLD……..
BECAUSE A PERFCT NATION MADE BY THEIR PEOPLE SO
GIVE A PERFCT LIFE TO THEM …………
