Contour Crafting

Basic need of Human

Social Needs-

(Love,Friendship,Happiness)

Security Needs- (Protection From

Danger)

Ego Needs –(Self Respect ,Autonomy )

Physiological Needs –(food ,Shelter)

Some Realistic Fact

Slow speedAccident rate at construction

sites is highCostly and always over budgetCorruption prone Labour efficiency is alarmingly lowWork quality is low

Limitation Of Current Manual System Of Construction

What is Contour Crafting?

Material feed barrel

Nozzle

Side trowel

Side trowel control mechanism

CC is a layered fabrication method which combines ancient surface forming concepts with modern robotics technology

Construction of house by cc method

Plumbing and reinforcement

Cost Portion ofConventionalConstruction

Due to If Automated by CC

20%-25% Financing

Short project length and control of time to market

will eliminate or dramatically reduce

financing cost

25%-30% Materials No waste in construction

45%-55% Labour

Manual labour will be significantly reduced. Muscle power will be

replaced by brain power.Women and elderly

workers for the first time will find new job opportunities in

construction.

Benefits by Contour Crafting

Experimental construction of hollow wall

Fact: Construction contributes significantly to harmful emissions and construction of a typical single-family home generates a waste stream of about 3 to 7 tons.Globally, more than 40% of all raw materials areconsumed in construction.1o CC offers construction without waste, noise, dust, orharmful emission.

Fact: 400,000 workers are seriously injured or killed in construction annually in the US.o CC can deliver construction without accidents, injuries, or litigation.

Fact: Any departure from standard rectilinear design significantly increases the cost of conventional construction.o Consider the possibility of new architectural designs for homes, neighborhoods and cities without attendant increases in cost.

Advantages of Contour Crafting

Lunar Construction Project –Sponsored by NASA

unsuitability of the available automated fabrication technologies for large scale products,

conventional design approaches that are not suitable for automation,

significantly smaller ratio of production quantity/type of final products as compared with other industries,

economic unattractiveness of expensive automated equipment, and

managerial issues

Limitation of Contour Crafting

Conclusion

Having Potential to build house

immediately in emergency

Offering more luxurious houses in

small time

Reducing accident and materials

wastage
