of 3D
Printing
• Concept of 3D printing
• How does it work?

3. History of
3D Printing
• 1983- Chuck Hull
Invented
Stereolithography
• Early 1930s- Commercial
3D Printing
• 21 Century – Self
Replicating 3D
Printers.
• Expansion of 3D
Printing. ( materials
and uses )
• Exploring 3D Printing

4. Benefits of 3D Printing

5. • 3D printing isn’t standardized
• Additive manufacturing impact on environment
• Equipment and product costs are high
• Knowledge gap
• Complicates intellectual property
• Limited material
• Restricted build size
• Lack of regulation
• High risk
Challenges of 3D Printing

6. 3D Printing (Current Scenario)
• Global 3D Printing market
• Valued at $13.84 billion in 2021
• Predicted to grow rapidly at a CAGR rate of 20.8% from 2022
to 2030 to reach value of $76.17 billion

7. 3D Printing In Nepal
In 2015, Zener Technology was first company which
bring idea of Commercial 3D print in Nepal.
They Created Nepal Idol 2018's Golden Mic.
House model for real state requiring over 1000 hour
of printing.

8. 3D Printing In
Nepal
Nepal's leading Biotech
Company, Centre for
Molecular Dynamic Nepal
run By Dibesh karmacharya
Developed a 3D printed
EEG Cap that saves 1000
dollar without scarifying
performance.

9. 3D Printing In Nepal
Mahabir Pun's
National
Innovation Centre
is also creating
high tech 3D
printer.

10. Different Model of 3D printing:
• Fused Deposition Model (FDM)
• Stereolithography (SLA)
• Selective Laser Sintering
(SLS)
• Digital Light Processing
(DLP)
• Selective Laser Melting
(SLM)
• Multi Jet Fusion (MJF)
• PolyJet
• Direct Metal Laser Sintering
(DMLS):
• Electron Beam Melting (EBM)

11. Application of
3D Printing
Prototyping and
Product Development:
Allow manufacturer to
quickly iterate & test
design before
mass production.
Eg. Scale Model of New
Car & it's Aerodynamic.
UITAL, BMW NEXT GEN

12. Application
of 3D Printing
Customized
Manufacturing:
Product which tailored
to individual needs
incorporating
complex geometrics.
Eg. Jewelry Designers
uses 3D printing to
create unique, One-Of-
a-Kind.

13. Applications of
3D Printing
Aerospace and Defense:
Light weight & high
performance components
for aircraft and
spacecraft.
Eg. NASA has successfully
3D Print rocket engine
part to reduce weight.

14. Application of
3D Printing
Medical and Healthcare:
Enables the production of
patient-specific medical
devices, surgical models,
and implants.
Eg. production of customized
hearing aids, where 3D
printing allows the
creation of comfortable,
precise-fitting devices
that enhance the user&
hearing experience.

15. Application of
3D Printing
Education and Research: Utilized
in educational institutions and
research facilities to enhance
learning experiences and
facilitate scientific
exploration.
Students can use 3D printers to
bring their design concepts to
life and understand abstract
concepts in a tangible manner.

16. Application of 3D Printing
Architecture and Construction:
In the construction industry by enabling the creation of complex
architectural models and even large-scale structures.
For instance, a 3D-printed model of a building can help architects
visualize and refine their designs, allowing for more efficient
construction processes.

17. Application of
3D Printing
Art and Design:
3D printing is an innovative tool for artists
and designers to explore new possibilities and
create unique art forms.

18. Application of
3D Printing
Automotive Industry:
3D printing is used in the
automotive sector for prototyping,
customization, and the production of
specialized parts.

19. Where does it lead to the
future?
• It will decrease human creativity
• Offering greater design freedom
• Enable decentralized production
• Reduce material waste
• Reduce Transportation need
• Sustainable and localized manufacturing
• Innovation & Customization will be normal
• 3D will unlock new possibilities in the future

21. 3D printing will be bigger than what 3D printing
companies are saying.
