This document contains information about 3D printing from two individuals - Anjali Deshmukh and R. Arun, both from the Civil Engineering department. It discusses the benefits of 3D printing such as reducing costs by finding design errors earlier. 3D printing allows functional product models to be created, helping identify issues like poor fit or ergonomics. The document also examines why 3D printing has not been applied to building construction yet and outlines some of the advantages it could provide such as reduced costs and timelines as well as increased design freedom and functional integration.

4. Objective:
3D Printing has revolutionised the way products are built. It is
used extensively for ideation, envisioning the product design with a model in
hand. It is possible to create functional models, which makes it easy for the
designers and engineers to validate the product designs and identify the errors
which otherwise would not have been noticed in virtual simulation and analysis,
especially the design fallacies related to fit, form and ergonomics. With a wide
range of materials available in different colours, the companies can now create
models that are astonishingly close to the real or final product.

5. What is 3D printing Technology:
3D Printing is a technique that deposits material layer by layer using a
head similar to that of an inkjet printer. The head tends to move along the X and
Y axes and the object being printed moves up and down on the Z axis. It is a
process whereby the information in a digital file describing an object virtually
(such as an STL or CAD file) is used to rapidly make a real object, usually by
one single machine and usually in limited production runs.

6. Need of study:
Reduce the cost of change and cost of error by identifying and rectifying design
errors earlier in the design cycle
Compress their design and development cycle time
Build robust products with superior functionality
Build jigs and fixtures to aid production line and quality control inspection
fixtures
Build products with great aesthetic appeal
Boost product design innovation
Development costs, and
And hit the market early.

“…the 3D printing technology has the potential to revolutionize the way we
make almost everything…”

8. WHY ARE WE NOT PRINTING BUILDINGS?

9. PROCESS IN 3D PRINTING:

10. BENEFITS FOR THE INDUSTRY =
MOTIVATION
• Introduction
• Courtesy of Foster + Partners
• Less human factor related problems due to automation
• Custom parts & just in time deliveries
• Greater design freedom at no or little extra cost
• Additional functionalities into structures
• System integration and reduction of material interfaces
• Better control over the deposition of build material
• Better internal and external finishes
• Structure as a homogeneous unit

11. 3D PRINTING IS COMPETITIVE WITH TRADITIONAL PROCESSES
AND PRODUCTS
Pilot studies show three key issues that affect how Freeform Construction
impacts traditional methods:
1) COST
2) TIME
3) VALUE ADDED

12. 2) TIME:
3) VALUE
ADDED:

13. ADVANTAGES:
 Rapid Prototyping
 Creation of Employment Opportunities
 Manufacture of Customized Products
Boon for Organ Donation

14. DEFECTS:
• Counterfeiting
• Manufacture of Dangerous Items
• Size Limitations
• Production of Unnecessary Stuff
