3D printing and its technologies

2. INTRODUCTION
• Additive Manufacturing- takes digital
input in the form of Computer Aided
Design (CAD) model and creates solid,
three-dimensional parts through an
additive, layer by layer process.
Where a 3D object is created by
laying down successive layers of
material.
• Subtractive Manufacturing- removal
of material by cutting or drilling to get
desired object.

3. WHAT IS 3D
PRINTING
• 3D Printing is often referred as
Additive Manufacturing.
• Like an office printer that puts 2D
digital files on a paper, a 3D Printer
creates 3-dimensional object by
laying down successive layers of
materials.
• 3D Printer can use Metals, Polymers,
Composites and other powders to
print components.

4. STEPS IN 3D PRINTER
1. Draw The 3D Model In Any 3D Software
2. Save/Convert it to .stl file which is
supported by 3D printersOpen the file on
the slicing software which means the
software provided by manufacturer of
printer
3. Start Layer Slicing Which means printer
start to slice each layerPrinting3D Card

5. FUSED-
DEPOSITION
MODELING (FDM)
• Fused deposition modeling
(FDM) is an additive
manufacturing technology
commonly used for modeling,
prototyping, and production
applications.
• In this process, parts are
printed by extruding molten
strings of material that melt
together to create part layer by
layer.
• Cheapest method and easy to
use.

6. MATERIALS USED IN FDM

7. WORKING OF 3D PRINTER
• Selective laser sintering-Selective
laser sintering (SLS) is an additive
manufacturing technique that uses a
high-power laser (for example, a
carbon dioxide laser) to fuse small
particles of plastic, metal (direct metal
laser sintering),ceramic or glass
powders into a mass that has a desired
3-dimensional shape).

8. APPLICATIONS OF 3D
PRINTING
•Designers use 3D printers to quickly
create product models and prototypes

9. ADVANTAGES OF
3D PRINTER
Rapid Prototyping-Process-3D printing gives designers the ability
to quickly turn concepts into 3D models or prototypes.
Clean -Wastage of material is negligible.
Complex Shape-Complex shape can be produced
Easy To Use- No skilled person needed of 3D Printers
Reduce Design Complexity -We can Create 3D model easily and
more efficient than ordinary methods.
Portable- 3D Printers Is Very Portable as checked to ordinary
molding methods.

10. DISADVANTAGES
Slowness-Process is slow but comparatively faster
than ordinary methods.
Strength-Components do not have enough
strength.
Cost Expensive-Cost Of Input Is Higher
Misuse-Although 3-D printers have the potential of
creating many jobs and opportunities, they might
also put certain jobs at risk.

11. CONCLUSION
• It significant decrease in product development cycle and costs.
• 3D Printing is a new technology which has many opportunities in real
world in many fields.it is use full in many industries which reduce time
,wastage, cost during development
