This document discusses 3D printing technology. It describes the different types of 3D printing including stereolithography, fused deposition modeling, electron beam melting, selective laser melting, and selective laser sintering. It explains the working principle of 3D printing which involves using CAD software to design an object, converting it to an SLF file, slicing the file, and printing the object layer by layer. The document outlines pros and cons of 3D printing such as complex shapes but limited materials. It also discusses future applications and improvements in sustainability.

3. Introduction
• 3D printing process builds a 3-dimensional
object.
• Object is made by using successive
adding the material layer by layer.
• This is also known as “Additive
Manufacturing.”
Modeling Printing Finishing

4. Types of 3D printing technology
• Stereo lithography (SLA)
• Fused deposition modeling (FDM)
• Electron beam melting (EBM)
• Selective laser melting (SLM)
• Selective laser sintering (SLS)

5. Working Principle
• For the printing, the object is created by
Computer Aided Design (CAD) or scanned the
actual object.
• After that it is converted in the form of (SLF)
Stereolithoghaphy File.
• Then this SLF file need to be processed by
“Slicer” which convert the material into a series
of layers.
• Printer resolution describe layer thickness in Dot
per inch (DPI) or µm.

6. Future scope
• The future of 3D printing is bright and became
an important pillar in various manufacturing
industries.
• e.g. (Medical, Aerospace, Automotive, Defense
Architecture etc.)
• 3D printing innovators are even exploring How
to make the process itself more sustainable.
• Researchers are focusing on how to print of
different material integration.

8. Pros and Cons
Pros :-
• Very complex shape can be produced.
• Less manufacturing time
• Flexibility & risk reduction
Cons :-
• Harmful emission
• Expensive & limited types of material can be
used.
• High energy consumption.

9. Conclusion
• 3D printing technology could revolutionize and
reshape the world.
• Advancement in this technology can significantly
change and improve the way of manufacturing
process.
• 3D printed product are of superior capabilities,
marketed quicker, design oriented
