2. Introduction
• 3-D printing is the construction of a three-dimensional object
from a CAD model or a digital 3D model.
• The printing can be done in a variety of processes in which
material is deposited, joined, or solidified under computer
control, with the material being added together typically layer
by layer.
• It is combines digital technologies to allow free from
construction without the use of formwork
3. History
• The first printer was developed by charles hull in1984.
• One of the application using 3D printing in the construction
industry started in the early 1990s.
• The earliest 3D printing manufacturing equipment was
developed by Hideo Kodama of the Nagoya Municipal
Industrial Research Institute, when he invented two additive
methods for fabricating 3D models.

5. Materials can be used in 3D Printing
• There are a variety of 3D printing materials,
including thermoplastics , resins, ceramics, carbon fiber,
cementitious material, sand and other admixtures.
6. 3d printing Technology in india
India’s first 3d printing post office in Bengaluru was built by
Tvasta Construction (IIT Madras Start-up).
7. Environmental Impact.
1. Major environmentally friendly.
2. Waste reduction.
3. Plastics, resin, certain metals, ceramics
. are used
4. No environmental impact
5. No pollution.
6. No waste.
8. Time consumption
1. Low time consumption.
2. one day is enough.
3. Within 42 Hours, 3D printer build a big house.
9. Advantages of 3D printing
• This technology allows for the easy creation of cheaper than
subtractive production methods as no extra material is used.
• Since no moulds are required, the costs associated with this
manufacturing process are relatively low. The cost of a part is
directly related to the amount of material used, the time taken
to build the part and any post processing that may be required.
• Because the process is based upon computer aided designs
(CAD), any product alterations are easy to make without
impacting the manufacturing cost.
10. • Although plastics and metals are the most common materials
used in 3D printing, there is also scope for creating parts from
specially tailored materials with desired properties. So, for
example, parts can be created with high heat resistance, water
repellency or higher strengths for specific applications.
11. Low cost.
• Low cost on both a large structure scale and regard to parts.
• Have potential for far lower material cost and labor.
• The printer does most of the work.
• In India cost ranges fro 5 lakhs to 5.5 lakhs.
• It is also depends on area, design and requirements.
12. Conclusion
• 3D printing technology is a major on the original
manufacturing technology which is slowly changes our
production and life.
• 3D Printing technology will play an important role in the
future of the building industry.
• 3D printing technology ability to deliver projects with
increased speed sustainability and reduced waste.
