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
Top trowel
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
