3. Overview of 3DPrinting
“3D printing” or “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.

4. Types of Manufacturing
Additive Manufacturing
Subtractive Manufacturing
Additive Manufacturing could
reduce energy use by 50% and
reduces material costs by up to
96% compared to traditional
manufacturing.

5. General Principles
1.Modelling:It takes virtual blueprints from modeling
software and “slices” them into digital cross-sections for
the machine to successively use as a guideline for
printing.
2.Printing:To perform a print, the machine reads the
design from an .stl file and lays down successive layers
of liquid, powder, paper or sheet material to build the
model from a series of cross section.
3.Finishing

6. A person creates a
3D image of an item
using a CAD
software program.
The CAD
information
is sent to
the printer.
The printer forms the
item by depositing the
material in layers—
starting from the
bottom layer—onto a
platform. In some
cases light or lasers
are used to harden the
material.
How Does It Work?

7. Methods of 3DPrinting
1.Selective LaserSintering(SLS)
2.Stereolithography
3.Fused DepositionModeling(FDM)
Stereolithography
FDM

8. Selective Laser Sintering
It is an additive manufacturing technique that uses a high
power laser( for eg. CO2 laser) to fuse small particles of
plastic, metal, ceramic or glass powders into a mass that
has a desired 3D shape.

9. Stereolithography
It is an additive manufacturing process that works by
focusing an ultraviolet (UV) laser on to a vat
of photopolymer resin.

10. Fused deposition modeling
It build parts layer-by-layer from the bottom up by heating and
extruding thermoplastic filament. Used for modelling,
prototyping and production applications.

12. 3D Printing Materials
1.Plastic FilamentAcrylonitrile Butadiene
Styrene (ABS)
PLA Polylactic acid or
polylactide (PLA, Poly)
Flexible Plastic (TPE) Nylon

13. 2.Metals
Brass, Bronze, Platinum, Silver and Gold
Steel Aluminum

14. Applications
1.Concept Modeling :This lets
small design and engineering firms
extend their reach by testing out
more ideas .
2.Functional Prototyping: It helps
in creating amazingly realistic
prototypes with the look and feel of
a real product.
Example:
Lamborghini, while developing its
new flagship model Aventador has
made extensive use of 3D printing
technology to build a
functional prototype of the car.

15. 3.Manufacturing Tools:
Quick, low-volume tooling
and custom fixtures give
manufacturers the flexibility
to embrace more opportunities.
4.End-User Parts
5.Food
6.Fashion & Retail
