3D printing is a process that creates three-dimensional objects from a digital file by depositing material layer by layer. It allows for quick production of customized objects without the constraints of traditional manufacturing. The most common type of 3D printer uses fused filament fabrication, which heats and extrudes plastic filament through a nozzle to build an object layer by layer. 3D printing offers advantages over conventional manufacturing like low-cost production of customized goods and on-demand creation without logistics.

2. What is 3D
3D stands for 3 Dimensions(X,Y and Z or we can say
Length, Width and Height).
Anything that we see using our naked eyes in real
world is in three dimensions or a 3D object.

3. What is Printing
Printing is the process of reproducing anything from
its digital file.

7. What is so special about 3D printing
With 3D printing you can print any digital file to a
real life object.
So you can design anything and get it built as a real
object quickly.

8. What all is needed for this
For 3D printing you need:
• 3D Digital version of the object
(in .stl format)
• 3D printer
• 3D printer filament

9. What is the need of 3D printing?
Though we have millions of things being made today
and you might feel it to be sufficient. But actually
there are too many constraints in these century old
manufacturing processes.
3D printing offers a solution to all those limitations

10. How are things made conventionally?
Before going into 3D printing we need to understand
how are things made. At large scale, manufacturing is
done by subtractive process where a block of material is
cut down to bring to required shape.
This is called as subtractive manufacturing, where we
reduce the size of initial product to achieve final
product.

11. 3D Printing vs Conventional Process
3D printing is also known as Additive Manufacturing,
where something is made by adding material layer by
layer.
A 3D printer deposits material layer by layer and hence
making the complete product. So it is just opposite to
the conventional process.

12. Advantage of 3D printing
• Low scale production is very costly by conventional manufacturing
practices, whereas with 3D printing it can be made inexpensively.
• Through 3D printing customized products, prosthesis can be made
very easily.
• Conventional processes have some designing constraints, which is
not there with 3D printing. If you can think something, 3D printing
can make it.
• No need of logistics- 3D printing will disrupt the centralized
manufacturing industry. Soon there will be no need of transporting
materials from place to place. You will be able to make it yourself.

13. FFF- Fused Filament Fabrication
3D printers are based on various technologies. The most widely
used being FFF. In FFF a filament is heated till it melts and it is
extruded through a nozzle to deposit material layer by layer.

14. FFF: How it works
Printing through FFF based 3D Printer happens in these
steps:
1. The 3D design is sliced in layers.
2. This sliced design is converted to G Codes using
slicing software.
3. This G Code is fed to the 3D printer which commands
the extruder’s movement and material deposition.

16. 3D printing uses
3D printing is being used extensively in Aerospace,
Architecture, Automobiles, Education, Jewellery,
Medical, Manufacturing, Rapid Prototyping, Textile and
many other fields.
3D Printing is a new technology. More and more
applications are being explored everyday.

17. Amazing 3D printing
• In Netherlands, a patient’s lower jaw was replaced with 3D printed
jaw.
• Doctors in Bangalore are using 3D printed body parts to pre plan
complicated surgery, hence reducing operation time.
• US FDA has approved 3D printed drugs. Soon you will be able to
download the composition and print medicines at home.
• Boeing made some parts of airplane using 3D printing hence
reducing the weight by as much as 30%.
• Fashion Designers have started printing clothes using 3D printers.

18. What are its limitations?
3D printing is its evolution process and till now only limited
number of material can be produced using it. But with the
development in technology, this barrier will easily be crossed.
The cost of 3D printing is high to replace entire conventional
large scale manufacturing.

19. AHA 3D & 3D printing
AHA 3D is among the pioneers in 3D printing and 3D printer
manufacturing in India.
AHA3D rolled out India’s first indigenous 3D printer in March 2012.
AHA 3D launched India’s first dual extruder 3D printer with soluble
support in Oct 2013.
AHA 3D’s ProtoCentre 1M alpha is India’s largest and most
sophisticated 3D printer in its category.
